- 00:07Very welcome to visiting lecture
- 00:09series Grand Round series today
- 00:12we're thrilled to have Professor
- 00:14Cason from Stanford with US, and.
- 00:18Doctor teams will introduce her in
- 00:21just a minute. I just wanted to.
- 00:28Thank everybody for thoughtful feedback
- 00:31about our prior grand rounds presentation.
- 00:34An and kind of a lively and really
- 00:39important discussion about about the
- 00:42presentation from Doctor Sattel.
- 00:45And with feedback that we've received
- 00:48where taking a number of steps,
- 00:51including looking at the composition of
- 00:54the visiting Lecture Series Committee and
- 00:58some of the practices of that committee.
- 01:01I think these changes will be very
- 01:04helpful for our Department. In the.
- 01:08Hoping our grand rounds venue be
- 01:11even more reflective of the efforts
- 01:15of our Department to develop.
- 01:18Community. But that is both diverse,
- 01:23equitable and inclusive,
- 01:24so I just want to thank everybody for
- 01:28the feedback that we received and.
- 01:31And with that Jack, once you take it away.
- 01:37Thanks John.
- 01:39I'm very pleased today to welcome
- 01:41Doctor Deborah Case and to give the
- 01:43annual lecture for the Division of
- 01:45Prevention and Community Research
- 01:47in the Department of Psychiatry.
- 01:48Doctor Cason is professor of
- 01:50psychiatry and behavioral Sciences
- 01:52in the section on bubbled mental
- 01:54health and population Sciences at the
- 01:56Stanford University Medical Center.
- 01:58She's leading researcher on the
- 02:00Inter relationship of trauma,
- 02:01PTSD and alcohol use.
- 02:03Doctor Kayson received her PhD
- 02:05in clinical psychology from the
- 02:07University of Missouri and completed
- 02:09a clinical internship and postdoc
- 02:11at the University of Washington.
- 02:13She then joined the Washington faculty
- 02:15in the Department of Psychiatry and
- 02:17Behavioral Sciences and founded a
- 02:19program to develop and test more
- 02:22iaccessible interventions for
- 02:23individuals with mental health
- 02:25symptoms following trauma in 2019,
- 02:26Doctor Cason joined the Stanford faculty.
- 02:30Doctor Caseness conducted critical
- 02:31studies on the treatment of PTSD and
- 02:34or substance use across a variety
- 02:37of populations.
- 02:38Sexual minority women, Native Americans,
- 02:40sexual assault survivors,
- 02:41torture survivors, active duty military,
- 02:43and in a variety of settings,
- 02:45such as in primary care,
- 02:48rural communities, an internationally,
- 02:50her research on PTSD and substance
- 02:53use is also focused on understanding
- 02:55how PTSD and substance use may
- 02:57influence one another.
- 02:59Doctor Kacian is the author of over
- 03:01130 publications and her research has
- 03:03been funded by the National Institute
- 03:05of Alcohol Abuse and Alcoholism,
- 03:08National Institute on Drug Abuse,
- 03:10National Institute on Minority
- 03:11Health and Health Disparities,
- 03:13the Department of Defense, Aquarian USAID.
- 03:15She is also the immediate past
- 03:17president of the International
- 03:19Society for Traumatic Stress Studies
- 03:20and a Fellow of the Association for
- 03:23Behavioral in Cognitive Therapies.
- 03:25The title of her talk today
- 03:27is comfortably numb.
- 03:29Research on the etiology and treatment of
- 03:32comorbid PTSD and alcohol use disorders.
- 03:35Doctor kayson
- 03:37thank you so much for that lovely
- 03:40introduction and thank you all for
- 03:42inviting me and for giving me a little
- 03:44bit of your time for this conversation.
- 03:47So just to start us off,
- 03:49I want to contextualize PTSD an why
- 03:51my career is focused on this around 40
- 03:54to 90% of Americans have experienced
- 03:57dramatic stress things like car accidents,
- 03:59assault, child abuse and combat.
- 04:01At some point during their lives,
- 04:03about 20% have experienced a
- 04:05traumatic event within the past year.
- 04:08And about 25 million Americans have
- 04:10PTSD and that was pre pandemic.
- 04:12Left untreated,
- 04:13about half of those with PTSD don't recover.
- 04:17In 2000, PTSD was estimated to cost
- 04:20the US economy about $40 billion per
- 04:23year and increased healthcare costs,
- 04:25decreased worker productivity
- 04:26and prescription drug costs.
- 04:28So this is a very expensive
- 04:30illness for us as a society.
- 04:33When we look beyond the United States,
- 04:35traumatic events and associated mental
- 04:37health consequences are a major contributor
- 04:39to the global Burden of Disease.
- 04:44So, just briefly, in terms of disclosures,
- 04:46I do have a commercial disclosures.
- 04:48I have consulted as a Advisory Board
- 04:50member for Jazz Pharmaceuticals.
- 04:52I also have a book published on
- 04:55Cognitive Processing Therapy from
- 04:56Elsevier that in theory someday I
- 04:58will receive royalties from and I do
- 05:01occasionally receive honorarium for
- 05:02conducting workshops or trainings on
- 05:04fighting their processing therapy.
- 05:06When I remember to build people
- 05:08for having done the training.
- 05:11Mom, I also want to thank all
- 05:14of my collaborators.
- 05:15This body of work that I'm going to be
- 05:17talking about today really has taken a
- 05:20village of wonderful smart collaborators,
- 05:22many of whom are far smarter than I am,
- 05:25and I want to thank my Thunder.
- 05:27Is that the National Institutes of
- 05:29Alcohol Abuse and Alcoholism and the
- 05:32National Institutes of Drug Abuse?
- 05:36But when we talk about PTSD,
- 05:38PTSD is far more likely to present
- 05:41with comorbidity than by itself,
- 05:43so respondents with PTSD or substantially
- 05:46more likely to develop their anxiety,
- 05:48mood, and substance disorders
- 05:50than those without PTSD.
- 05:52And what's interesting is this
- 05:54is not a factor of trauma.
- 05:56Exposure really seems to
- 05:58be a factor of active PTSD,
- 06:00which is where you see the elevated
- 06:03risk of secondary disorders.
- 06:05Now I'm going to be focusing a
- 06:07bit on relationships between PTSD
- 06:09and substance use because they're
- 06:11commonly comorbid as we're going
- 06:13to discuss in just a second and
- 06:15their associated with a much more
- 06:17severe course for both disorders.
- 06:22So if we look at people with PTSD
- 06:25out of every hundred, about 52,
- 06:27so a little more than half of an alcohol use
- 06:30disorder and 35 have a drug use disorder.
- 06:33When we look at some more recent analysis,
- 06:37this is from recent epidemiological
- 06:40data from the new Spark data set that
- 06:43half of people with lifetime PTSD
- 06:46also have lifetime alcohol use to
- 06:49disorder when look among treatment
- 06:51seekers with substance use disorder,
- 06:53about 60% have comorbid PTSD.
- 06:56When we look within past year PTSD.
- 07:00What we find is about 1/3 of people have some
- 07:03type of comorbid substance use disorder,
- 07:06either an alcohol use disorder,
- 07:08a substance use disorder,
- 07:10severe drug use disorder, or both.
- 07:17Now, one of the challenges with this is
- 07:19that when these two disorders Co occur,
- 07:22patients struggle much more.
- 07:24So PTSD and substance use is associated
- 07:27with an earlier onset of the substance
- 07:30use disorder and more years of use.
- 07:32They also associated with more
- 07:34severe symptoms, fire, suicidality,
- 07:36more, psychiatric comorbidity,
- 07:37and worse treatment opens on
- 07:39that is both in terms of their
- 07:42reductions in substance use and their
- 07:44likelihood to drop out of treatment.
- 07:49So why do these two disorders
- 07:51tend to go together?
- 07:52Well, there are several different theories.
- 07:56The one theory is a high risk model.
- 07:59Which is that if you are using substances,
- 08:02it increases your risk of experience,
- 08:04a traumatic event,
- 08:05and that in turn influences
- 08:07your risk of developing PTSD.
- 08:09And there is data that supports this model.
- 08:12So for example, if you look at research
- 08:14around the relationship between
- 08:16alcohol use and sexual victimization,
- 08:19be if you look at some data that was
- 08:22collected at a daily level on days
- 08:24of why drinking so binge drinking,
- 08:27what we find is for women,
- 08:29their risk of being sexually assaulted
- 08:32on that day increases about 9.
- 08:34If all this compared to non drinking days
- 08:36when we look at these of lighter drinking,
- 08:39what we find is there's a fourfold increase.
- 08:42So the idea with this models
- 08:44you might be in situations or
- 08:46settings where you're more at risk
- 08:48for experiencing trauma that.
- 08:50Does it mean that the substance
- 08:52used caused the trauma,
- 08:53but it may have left you
- 08:55slightly more vulnerable.
- 08:59Now the model that has the most empirical
- 09:01support and also has been investigated the
- 09:03most often is the self medication model,
- 09:06which is that people use alcohol to cope
- 09:08with PTSD and this one is is a model that
- 09:11is frequently endorsed in popular culture.
- 09:14Many people have this belief.
- 09:15I had a flight that was cancelled
- 09:18once an everybody in the line,
- 09:20for example, was saying, you know,
- 09:22let's go get a drink, right?
- 09:24That's an example of the
- 09:25concept of self medication.
- 09:27This is distressing to me.
- 09:29And so I will call for alcohol use.
- 09:31The Despond slept with this model is that
- 09:34alcohol use is negatively reinforcing.
- 09:37What that means is so let's say this
- 09:40person has a memory of a tremendous event,
- 09:44right for distress goes up.
- 09:48She then thinks about drinking.
- 09:50Perhaps she has a drink.
- 09:54And their anxiety immediately decreases,
- 09:56so the negative reinforcement
- 09:58leads to reductions in anxiety.
- 10:00Now, unfortunately,
- 10:01what that does is it increases your
- 10:04likelihood of returning to drinking
- 10:06in the future with the same queues.
- 10:12So you can see then there's this
- 10:15reduction in drinking urges.
- 10:16Now there's another theory that has
- 10:19slightly less empirical support.
- 10:21It's also been looked at less
- 10:23frequently than self medication,
- 10:25which is the mutual maintenance model
- 10:27and the idea with this is that the
- 10:31two disorders maintain one another.
- 10:33So with PTSD that leads to both coping
- 10:36beliefs and also acute cravings, that
- 10:39increases the likelihood to use substance.
- 10:41Symptoms of substance use.
- 10:43Withdrawal can also
- 10:44resemble symptoms of PTSD.
- 10:46You could have increased anxiety.
- 10:48You can have an increased sleep
- 10:50disturbance and that can increase
- 10:52PTSD symptoms or can look like PTSD.
- 10:54You also get avoidance
- 10:55of trauma related cues.
- 10:57There is some data supporting this theory,
- 10:59but somewhat less,
- 11:00and the relationship seems to be less strong
- 11:03than what we see with self medication.
- 11:06Now.
- 11:06Why are these theories important?
- 11:08Well,
- 11:08they may drive approaches for treatment,
- 11:10and that's what we're going to be
- 11:13talking about in most of the top.
- 11:16Now I do want to acknowledge
- 11:18that it's also possible,
- 11:20and in fact likely that there are
- 11:22third variables that increase risk
- 11:24for both substance use and PTSD,
- 11:27so that might be helping.
- 11:28Skills deficits are coping skills,
- 11:30strategies.
- 11:31It might be a genetic or other
- 11:33committed biological vulnerability,
- 11:34and that might affect risk
- 11:36for both disorders.
- 11:40So let's move into talking
- 11:41about treatment and what do we
- 11:43know right now about treatment?
- 11:45So there are several ways that we can
- 11:48go forward with treating Co occurring
- 11:50PTSD and substance use disorders.
- 11:53The one option is to do an integrated
- 11:56treatment where you treat the substance
- 11:58used in the PTSD at the same time.
- 12:01These might be treatments,
- 12:02life seeking safety,
- 12:03which I'm going to talk about in just
- 12:07a second or two months like hope.
- 12:10Where the therapies are integrated,
- 12:11there are some advantages to
- 12:13these types of treatments.
- 12:14There is some data that patients prefer.
- 12:16The concept of integrated treatment
- 12:19where they're getting skills for both.
- 12:22I think there are a couple of challenges
- 12:24with these approaches as well,
- 12:26though often they are longer
- 12:28than the sole target treatments.
- 12:30They may be a little bit more
- 12:32complicated for providers to learn.
- 12:34They have to learn multiple behaviors.
- 12:36Farm and drop out his eye.
- 12:41So and what we find is,
- 12:43at least in some of the research studies,
- 12:46the integrated treatments do
- 12:47not always work better than the
- 12:49single treatments in PTSD.
- 12:51So this is a relatively recent paper,
- 12:54not super recent.
- 12:55This was looking at seeking safety
- 12:57as compared to treatment as usual
- 12:59as compared to relapse prevention,
- 13:01which is a substance use oriented treatment.
- 13:04And what we think of is actually
- 13:06relapse prevention work pretty
- 13:08well in addressing PTSD,
- 13:09slightly better than seeking safety.
- 13:15It did not significantly better.
- 13:17We also did not find that seeking safety
- 13:20worked better than relapse prevention.
- 13:22In addressing the substance
- 13:24use symptoms in this study.
- 13:27So it may not be always the best option.
- 13:32Now another option is to do
- 13:34two different treatments,
- 13:35so it used to be that back in the old
- 13:38days when I was in Graduate School,
- 13:41we were taught that what you
- 13:43need to do is have the person go
- 13:46have their substance use treated,
- 13:48stabilize them and then treat the PTSD.
- 13:50So the idea of sequential care,
- 13:52often therapists are quite concerned
- 13:54that patients are going to relapse
- 13:56or going to have difficulty
- 13:58tolerating a PTSD treatment,
- 13:59and so that's where some
- 14:01of this idea comes from.
- 14:03Now the challenge with this approach.
- 14:06Is that the data around it?
- 14:08This is what's often seen in practice.
- 14:11Is that?
- 14:14For some patients,
- 14:15with their saying is look,
- 14:17it's my PTSD that's triggering
- 14:19my desire to use,
- 14:21and so you're asking me to not use,
- 14:24but you're not giving me coping
- 14:27skills and so that can be a challenge.
- 14:30But data on whether substance
- 14:32use also reduces reduces.
- 14:34PTSD is a bit mixed at this
- 14:36point in the literature,
- 14:38and there is some data that unremitted
- 14:41PTSD is a predictor of later relapse.
- 14:44Following substance use treatment.
- 14:49Yeah, So what we know is that
- 14:52people with PTSD do appear to
- 14:54have some out worse outcomes.
- 14:56Generally in substance use treatment,
- 14:58although I do want to point out that
- 15:00substance use treatments defined
- 15:01fairly broadly in these studies,
- 15:04so it's not necessarily
- 15:05always manualized treatments,
- 15:06but we do see that people with
- 15:08PTSD and substance use treatment
- 15:10have higher rates of re admission.
- 15:13Lower adherence, mayor dropout.
- 15:14They have shorter periods of
- 15:17abstinence and higher use of services.
- 15:19For compassion, for patience as well,
- 15:21with this approach is that patients
- 15:23can get bounced around right?
- 15:24So they try to get treatment for PTSD.
- 15:27They are told they need to get
- 15:28the substance use treated first,
- 15:30but the substance use provider
- 15:32may not know what to do with the
- 15:34trauma and that can be a challenge.
- 15:38Now another option is to do
- 15:40two different treatments,
- 15:41so to treat the PTSD and then
- 15:43perhaps be the substance use.
- 15:45If it's still an area of concern.
- 15:50So there is data that treating
- 15:52the PTSD directly does appear to
- 15:55reduce substance use symptoms.
- 15:57And there hasn't been data supporting the
- 15:59idea that people have yatra genic effects.
- 16:02Now I do want to put in a caveat
- 16:04that these studies also still
- 16:06have high rates of dropout,
- 16:08which is problem one of the PTSD substance.
- 16:11Use treatment literature as you're going
- 16:13to see as I show you some later data.
- 16:17But what I want to do now
- 16:20is actually 50 years,
- 16:21just a little bit and talk about some
- 16:24research that crazy Simpson and I did.
- 16:26Basically was the Pi for this study,
- 16:29and this was actually not designed
- 16:31to be clinical trial per say.
- 16:33This was actually an experimental study
- 16:35to try to understand mechanisms of
- 16:37change in PTSD alcohol treatments to try
- 16:40to look at a very condensed treatment,
- 16:42and whether that could affect
- 16:44day-to-day symptoms as well as
- 16:46whether skill use made a difference.
- 16:48Now the concept.
- 16:49Find this study is when we talk
- 16:51about mechanisms of change.
- 16:53Often we will say here's the treatment
- 16:55and we may have theories about what's
- 16:57effective or not effective in the treatment,
- 17:00and then we do as we study the outcomes.
- 17:03But we don't tend to study the magic
- 17:05in the middle to really evaluate
- 17:08whether that is what is contributing
- 17:11to making the behavioral change.
- 17:13For this study,
- 17:14we recruited 78 people who had comorbid
- 17:16PTSD and alcohol use disorders.
- 17:18This was a fairly chronic and severe sample.
- 17:21Most people had tried other treatments.
- 17:23We also had a fair amount who tried
- 17:26residential treatment in the past.
- 17:28It was a mix of community members
- 17:31and veterans.
- 17:3230 two people got cognitive restructuring,
- 17:3426 data.
- 17:35Very brief,
- 17:36experiential acceptance intervention,
- 17:37and 20 had a nutrition control
- 17:39who's teaching people about bottom
- 17:41image portion portion sizes.
- 17:43For example,
- 17:44I'm going to mostly focus on the cognitive
- 17:47restructuring data for this talk now.
- 17:50The cognitive restructuring intervention.
- 17:52Actually all of the
- 17:53interventions were quite brief.
- 17:55It was a 90 minute scripted intervention fit
- 17:58off the basic skills of cognitive therapy.
- 18:02So how do you notice when something happens?
- 18:05What you tell yourself and how you feel and
- 18:08then some basic challenging of those beliefs.
- 18:11People also got for follow up 20
- 18:14minute booster sessions to just
- 18:16help them with skill maintenance.
- 18:18Light, brief.
- 18:19As an aside,
- 18:20we consulted a doctor.
- 18:22Reset was the developer of CPT,
- 18:24was a consultant on this study and
- 18:27she had quite a bit of skepticism
- 18:29that we would see any changes
- 18:32in behavior with this brief.
- 18:34In light attached with this kind
- 18:36of clinical population.
- 18:41So here is what we found,
- 18:44so this was a daily diary study so people
- 18:47used IVR to look at relationship between
- 18:51drinking PTSD and still use for about 30
- 18:55plus days following the intervention.
- 18:57We also collected baseline data which
- 19:00is controlled for in these analysis to
- 19:04get a sense of what they're drinking
- 19:07was like and what their level of PTSD
- 19:10was like before the intervention.
- 19:12So what you can see here?
- 19:15Yes that we had some some various effects.
- 19:17We've done that alcohol consumption just
- 19:19in terms of covariates was greater for men,
- 19:22which we would expect greater for
- 19:24those who are older and higher on
- 19:26weekends compared to weekdays.
- 19:27None of that. Is a particular surprise.
- 19:30We found that heavier basement drinking
- 19:32was associated with more drinking on a
- 19:35given day during the follow up period.
- 19:37And having completed more coaching calls
- 19:39was associated with less drinking on a
- 19:42given day during the follow up period,
- 19:44we had a main effect for the cognitive
- 19:47restructuring condition compared to
- 19:48control and had a significant interaction.
- 19:50So what we found was for the cognitive
- 19:53restructuring group they had about
- 19:55a 2% decrease in drinking per day
- 19:57as compared to control. That's 2%.
- 20:00Doesn't sound like very much.
- 20:02Although again with a very light touch
- 20:04intervention, it is quite pleasing.
- 20:06But what this means is that an
- 20:08individual who consumed 10 drinks
- 20:10the day after receiving the cognitive
- 20:12restructuring intervention would have
- 20:13been down to 5 drinks during the final
- 20:16day of the follow up period,
- 20:18and that is a notable decrease in drinking.
- 20:24What we thought was even more impressive.
- 20:27An interesting in terms
- 20:29of informing our thinking.
- 20:31Was that we could see a clear
- 20:34relationship between skill
- 20:36use and changes in drinking,
- 20:38so we were really interested
- 20:40in the Association requirement
- 20:42around mechanisms of change.
- 20:44What we found was that using more
- 20:48cognitive restructuring coping
- 20:49skills was associated with even
- 20:51greater reductions in drinking
- 20:53for the cognitive restructuring
- 20:56condition in particular.
- 20:58So these are some relationship
- 21:00between skill use in our controls,
- 21:02which is not entirely surprising,
- 21:04but really an Association between
- 21:06use of skills for those who
- 21:09are actually taught the skills.
- 21:11Now this is incredibly important
- 21:13because it identifies an active
- 21:15ingredient in treatments for
- 21:17PTSD and alcohol use disorders.
- 21:19And demonstrates that you can see
- 21:21an Association and the use of that
- 21:24skill and changes in alcohol use.
- 21:26This has led directly to a body
- 21:28of research trying to look at a
- 21:30higher dose of cognitive therapy
- 21:31for the treatment of PTSD and
- 21:33alcohol use disorders,
- 21:34which is what I'm going to focus on.
- 21:40So for those of you who are not familiar
- 21:42with cognitive processing therapy,
- 21:44CPT is an evidence based therapy for PTSD.
- 21:47It's been evaluated more than 20 randomized
- 21:50clinical trials and multiple other
- 21:52types of less rigorous trials as well.
- 21:54It is a 12 session therapy.
- 21:57It can be delivered in groups or individually
- 21:59and it is predominantly cognitive.
- 22:02It's focused on trauma processing mostly
- 22:04through the use of Socratic dialogue
- 22:06or asking really good questions.
- 22:09And I'm done helping the person evaluate and
- 22:12shift beliefs about why the trauma happened.
- 22:15As well as overgeneralized beliefs from the
- 22:18traumatic event to their present or future.
- 22:20We were particularly interested in
- 22:22looking at this therapy because it
- 22:24does not contain an exposure element.
- 22:29So the first today I'm going to
- 22:30talk about is in the talk about
- 22:33our longstanding collaboration and
- 22:34research trial with a rural Native
- 22:37American tribe in Washington state.
- 22:41So, just to contextualize this research,
- 22:43study as we move into this,
- 22:45I want to talk this briefly about
- 22:48the concept of syndemic theory.
- 22:50So within the context of historical
- 22:52trauma from high levels of
- 22:54poverty and discrimination,
- 22:55what you can see **** endemics of trauma,
- 22:59exposure, substance use in HIV risk
- 23:01behavior so it's endemic is the
- 23:03aggregation of concurrent or sequential
- 23:05epidemics or disease clusters,
- 23:07which exacerbate the prognosis
- 23:08and burden of disease.
- 23:10So when we talk about comorbidity research
- 23:13like the research I've been talking
- 23:15about with PTSD and substance use,
- 23:17we tend to focus on the boundaries
- 23:20and overlap of diagnosis.
- 23:22Syndemic theory focuses on communities
- 23:24that are experiencing Co occurring
- 23:26epidemics that additively increase
- 23:28negative health consequences.
- 23:30So for this community,
- 23:32what we see is PTSD concurrent with
- 23:35HIV that leads to more rapid HIV
- 23:38disease progression for survival,
- 23:40greater costs and services and
- 23:43lower adherence to medical.
- 23:45Very few HIV interventions address some
- 23:48of the risk factors such as trauma,
- 23:50exposure, mental health and substance use.
- 23:53An other researchers found that
- 23:55interventions that failed to do so have
- 23:58poor rates of condom use in health outcomes.
- 24:01Outcomes are worse for those with PTSD.
- 24:04This image is an odds the boarding schools
- 24:07which did affect this community as well,
- 24:10were Native American children
- 24:11were removed from their phones,
- 24:13isolated from their communities.
- 24:16And were rates of child abuse
- 24:18for actually extremely high.
- 24:22So this particular project was was
- 24:24a community based participatory
- 24:26research project address,
- 24:27comma related symptoms,
- 24:28and improve the health and well
- 24:30being of Native American women
- 24:32whose community initiative initiated
- 24:34so they approached University
- 24:35of Washington at the Indigenous
- 24:37Wellness Research Institute and
- 24:39asked for help with addressing
- 24:42trauma within their community.
- 24:44In partnership,
- 24:45we went through and talked about
- 24:47various treatment options and
- 24:49they felt that CPT would be a
- 24:51good option for them based on
- 24:53international work that I had done
- 24:56with evaluating adapted CPT in
- 24:58Northern and Southern Rock and in
- 25:01the Democratic Republic of Congo.
- 25:03So the idea behind this project
- 25:05is if we treat the PTSD,
- 25:07do we see reductions in alcohol
- 25:09and substance use,
- 25:10and can we also see reductions
- 25:11then in high risk sexual behavior?
- 25:16So for this particular study,
- 25:18in part because it was the first clinical
- 25:22trial to evaluate treatments for PTSD.
- 25:25Within the Native American community,
- 25:27to think about that for a minute
- 25:30with this community is the first
- 25:33novel file in a very high risk.
- 25:35Collation we had 70 three women from
- 25:38Pacific Northwest Travel Reservation.
- 25:40About 71% had a high school degree about
- 25:43Path had a primary partner baseline
- 25:45with high rates of palm exposure and
- 25:48substance use disorders which I'm
- 25:50going to show you in just a sack.
- 25:53About 35% of the individuals in
- 25:55this particular County or below
- 25:57the poverty line as compared to
- 25:5914% in the state of Washington.
- 26:03So in terms of comics Ledger we
- 26:05had was about three and four had
- 26:08experienced child sexual abuse,
- 26:10about three and four reported lifetime
- 26:12physical assault and two out of every
- 26:15three met full criteria for PTSD.
- 26:17We did take subthreshold PTSD
- 26:20in this particular trial.
- 26:2270% my criteria for substance abuse or
- 26:25dependence and 60 four reported binge
- 26:27drinking in terms of substance abuse.
- 26:30At 60% my criteria for dependence
- 26:32and 10% for abused.
- 26:34Predominantly alcohol with a smaller
- 26:36subset that were misusing cannabis.
- 26:42So couple things to point out.
- 26:44In this we had about a 43% dropout from CPT.
- 26:48That's fairly comparable with other PTSD
- 26:51substance use trials and we had about
- 26:53a 33% dropout for delayed treatment.
- 26:55We had much greater problems in
- 26:57this study with loss to follow
- 27:00up around assessment measures,
- 27:01even over a very brief follow-up period.
- 27:04I think in part because that that
- 27:06piece of it was less compelling.
- 27:13So the dig into some of the results.
- 27:15So this is the data on CPT
- 27:18as compared to the wait list.
- 27:20What we found out was that among the
- 27:22participants in the immediate intervention
- 27:23condition as compared to participants
- 27:25in the wait list control condition,
- 27:27we had an 8 point greater post baseline
- 27:30reduction in PTSD symptoms severity.
- 27:32This is miss somewhat lower drop in
- 27:34PTSD and then we see another CPT trials.
- 27:37I think reflecting the level of
- 27:38severity of distress in the population,
- 27:41we also found a dose effect where.
- 27:43Each additional CPT session
- 27:46attended was associated with 1.3.
- 27:50Greater reduction in PTSD symptoms and
- 27:52just to clarify everyone in the wait list.
- 27:54Then received the PT.
- 27:56We didn't leave people dressed in white.
- 28:00In terms of our hypotheses around
- 28:02substance use, what we saw was a
- 28:05significant decrease in alcohol use for
- 28:07the people received, CPT announced.
- 28:08There was a 1.4 greater reduction
- 28:10in the frequency of alcohol use
- 28:12and a .8 point greater reduction in
- 28:15the frequency of illicit drug use.
- 28:17A smaller effect.
- 28:18But we also have fewer people
- 28:20using illicit drugs.
- 28:21We felt we had no significant
- 28:24differences in alcohol problems,
- 28:25total sexual risk behaviors and
- 28:28rates of non condom protected sex
- 28:31and we saw fewer effects than
- 28:33we would have liked on HIV risk.
- 28:35We did see again a dose effect for
- 28:38each additional CPT session attended
- 28:41was associated with a .4 greater
- 28:43reduction in alcohol problems.
- 28:45Now just to follow up on this where we
- 28:48are now with this body of research,
- 28:51we found that on average the women
- 28:54attended about 6 missions and so based
- 28:56on this right now what we're looking
- 28:59at is the use of narrative exposure therapy,
- 29:02which does not involve
- 29:04practice between sessions.
- 29:05It has no writing component.
- 29:07It's been used extensively with refugees
- 29:09and was developed predominantly for
- 29:11use in low and middle income countries,
- 29:13and we're comparing that to motivational
- 29:16interviewing versus skills training.
- 29:17To try to dig in a little bit more about how,
- 29:21how can we help get some at HIV risk
- 29:23behaviors down as well with this community?
- 29:26And that trial is,
- 29:27I think about five artist.
- 29:28Spence,
- 29:29short of being completed,
- 29:30so I have answers for you about
- 29:32how that worked in a little bit.
- 29:36So I'm going to shift gears just yet
- 29:39again and talk about another child where
- 29:42we really did try to dig in on this
- 29:46question of which roots might help the
- 29:48most based on the body of literature
- 29:51around treatment of PTSD and substance.
- 29:53Use the based on this prior body of work.
- 29:57It's worth evaluating.
- 29:58At least we felt it was the
- 30:00alternative approach of predominantly
- 30:02targeting one or the other disorder.
- 30:05The field of PTSD,
- 30:07substance use, comorbidity,
- 30:08move very quickly to integrated treatments.
- 30:10Without many studies focused on
- 30:12PTSD treatments as a potential
- 30:15pathway to recovery,
- 30:16So what we were interested in is
- 30:19if you use a high quality PTSD
- 30:22therapy as compared to high quality
- 30:25alcohol use disorder therapy.
- 30:27What happens with both the primary
- 30:30target disorder and the secondary
- 30:33disorder during the course of treatment?
- 30:36And our idea with this is that
- 30:38this may help improve treatment.
- 30:41An informed standard practice.
- 30:42So we recruited from the VA and
- 30:44Community and randomize people to CPT,
- 30:46relapse prevention or daily assessments.
- 30:48Let me show you that.
- 30:53So individuals randomized now
- 30:54for this particular study,
- 30:55and there are some results that
- 30:57I'm not going to delve into
- 31:00just in the interests of time.
- 31:02During this phase of the trial here.
- 31:05People were conducting IVR assessments
- 31:08daily both through two week baseline and
- 31:11then over the 12 weeks of treatment.
- 31:15Six weeks for assessment only.
- 31:18So that we could actually study
- 31:20over the course of therapy.
- 31:22Some of those questions that we looked
- 31:24at in that smaller trial of are we
- 31:26seeing skills use make a difference and
- 31:28how can we understand the process of
- 31:31change during the course of therapy?
- 31:33I'm not going to go into those results today,
- 31:36but I do want you to be aware
- 31:39of that part of this study.
- 31:42So in terms of this child,
- 31:43what I'm going to be talking
- 31:45about is this initial comparison,
- 31:47and then also the results for the long term.
- 31:49Follow up for the group that
- 31:52were collapsed in.
- 31:53Randomized so with this particular project,
- 31:57randomization was stratified by gender.
- 31:59PTSD severity and alcohol use severity.
- 32:02People had to meet full criteria for PTSD.
- 32:06On an for an alcohol use disorder.
- 32:09And they needed to be willing to
- 32:11think about changing their drinking.
- 32:13The exclusion criteria were uncontrolled,
- 32:15psychotic manic symptoms,
- 32:17recent suicide outer homicide,
- 32:18ality if they were currently
- 32:20in a violent relationship,
- 32:22or if they were experiencing
- 32:24withdrawal symptoms,
- 32:25and if their medications have been changed.
- 32:28If they had taken an abuse in the past month,
- 32:32or if they were already in an evidence
- 32:35based PTSD or alcohol use treatment.
- 32:40With this therapy for this trial.
- 32:43What we did is we ask that each treatment
- 32:46be delivered in a non adapted way.
- 32:49So what that means for CPT is
- 32:51the drinking was addressed.
- 32:53It was addressed when it functioned
- 32:55as avoidance and it was addressed.
- 32:57If there were particular cognitive
- 32:59distortions about drinking that were
- 33:01getting in the way of recovery from
- 33:04PTSD and participants were encouraged
- 33:06to use the CPT skills to work on alcohol
- 33:08related thoughts when they came up.
- 33:11But it wasn't a major focus
- 33:13in the therapy sessions,
- 33:14except in these cases.
- 33:16In relapse prevention,
- 33:18PTSD was addressed as a trigger
- 33:20for craving or drinking.
- 33:22And was addressed when excuse me,
- 33:24but in explicit discussion of trauma,
- 33:27memories was prohibited.
- 33:32So in terms of what we controlled for and
- 33:35just the demographics about the sample,
- 33:38the sample on average was about 42.
- 33:43101 participants most of
- 33:45our participants were white,
- 33:47followed by African Americans.
- 33:50Individuals who were multiracial in
- 33:53a smaller subset were Asian Native
- 33:56American and about 21% were Hispanic or.
- 34:01Most the single and never married
- 34:0433% were college graduates and 38%
- 34:06were working full or part time,
- 34:08so it's a fairly impoverished sample.
- 34:12I did find that associate different
- 34:14demographic variables were nonsignificant,
- 34:16but a higher proportion of individuals
- 34:19in the relapse prevention condition
- 34:21were employed about 58% and had
- 34:24annual household incomes above 40%.
- 34:27All of our models that I'm going to be
- 34:30discussing controlled for differences
- 34:32in PTSD and drinking outcome.
- 34:35Or excuse me.
- 34:36All of the models controlled for
- 34:38sociodemographic variables of sex,
- 34:40age, race, and ethnicity,
- 34:41employment status, and treatment site.
- 34:45Treatment was conducted at a community
- 34:48trauma clinics as well as the Seattle VA.
- 34:52So let's look at how each active condition
- 34:55did as compared to daily monitoring.
- 34:57With weekly Checkins or
- 34:59the control condition.
- 35:00Now these are intent to treat analysis.
- 35:02The first set that I'm going to show you,
- 35:06it looks at the effects of CPT and relapse
- 35:09prevention as compared to assessment only.
- 35:11These are mixed effects models
- 35:13that include fixed effects for
- 35:14covariate condition and condition
- 35:16by time interaction terms.
- 35:20So what we saw in this initial this
- 35:22is just baseline to post treatment.
- 35:25Was that there was a significant
- 35:28improvement overtime across all conditions.
- 35:32We also did find an interaction
- 35:34with time by condition effects
- 35:36that were significant for CPT
- 35:38versus assessment only in the model
- 35:40predicting PTSD symptoms severity.
- 35:42Now it wasn't significant,
- 35:44but relapse prevention also was associated
- 35:46with decreases in PTSD symptoms
- 35:48severity as compared to assessment only.
- 35:50But as I say, it didn't actually
- 35:53hit the mark for statistics.
- 35:59We did find that both active treatment
- 36:02and dish conditions were associated
- 36:04with reductions in drinking and
- 36:06as compared with assessment only.
- 36:08But this interaction boots.
- 36:10Did not reach statistical significance.
- 36:15In terms of reductions
- 36:17in heavy drinking days,
- 36:19what we found was a statistically
- 36:22significant difference from baseline
- 36:24to post treatment for both their
- 36:26face as compared to assessment only.
- 36:29What we found was that those in CPT had
- 36:33about a 50% greater decrease in heavy
- 36:36drinking days as compared to assessment only.
- 36:39Relapse prevention participants had a 66%
- 36:41greater difference or greater decrease.
- 36:46So let's talk about change overtime.
- 36:48One of our primary questions was
- 36:51would these changes be maintained?
- 36:54And so for this second set of
- 36:56analysis with this includes the
- 36:58people who were re randomized,
- 37:00what initially got an assessment
- 37:02only were re randomized after
- 37:05their initial follow up.
- 37:06And so for those originally in
- 37:08the assessment on my condition,
- 37:10the first follow-up was treated
- 37:12as their pretreatment timepoint.
- 37:16The treatment and assessment completion
- 37:18rates were definitely not optimal,
- 37:21so about 52% as compared to 58% of CPT
- 37:26versus relapse spread to people attended
- 37:2975% or more of treatment sessions.
- 37:34On what you can see is really
- 37:36a substantive decrease,
- 37:37and people are making it to that one year.
- 37:41Follow up. Wait for that final follow up,
- 37:43but this is unfortunately pretty
- 37:45consistent with what we see in the
- 37:48PTSD stuff into the literature.
- 37:50Which is, it's really hard
- 37:51to hang on to these folks.
- 37:54Treatment completion rates.
- 37:55Actually, I think it's interesting
- 37:58that they are quite similar for
- 38:00CPT versus relapse prevention.
- 38:02And again,
- 38:03I think it argues that people can
- 38:05tolerate trauma focused therapies,
- 38:07or at least in anymore ************.
- 38:09Then another effective treatment.
- 38:15So what we found is that both
- 38:18treatments were associated with
- 38:20reductions in PTSD overtime.
- 38:22These were substantial reductions
- 38:24in PTSD symptoms severity,
- 38:26prevalence of meeting criteria
- 38:28for PTSD remission ranged from
- 38:30about 23 to 41% across the follow
- 38:33up time to meet some conditions.
- 38:37We also found that both treatments
- 38:39were associated reductions
- 38:40in days of drinking overtime.
- 38:45And that both treatments were
- 38:47associated with substantial reductions
- 38:49in days of heavy drinking overtime.
- 38:52We did see that those in relapse
- 38:55prevention showed statistically
- 38:56significant greater reductions in
- 38:58heavy days of drinking from pre to post
- 39:01treatment as compared to those in CPT.
- 39:04So it's about a 45% greater reduction
- 39:06in heavy drinking days and the ranges
- 39:09of those meeting criteria for low risk
- 39:13drinking range from about 42 to 52%.
- 39:18Now, with this particular study,
- 39:20what I would say in terms of take,
- 39:22some take home messages is that both
- 39:25treatments had significant significant
- 39:27effects on both primary and secondary tar.
- 39:29So more people assigned to CPT than
- 39:32relapse prevention experienced
- 39:33in early remission from PTSD,
- 39:35which may be helpful for some
- 39:37patients in reducing relapse risk.
- 39:39Don't treatments were associated with
- 39:41reductions in drinking relative to
- 39:43assessment, only at post treatment,
- 39:46and those early reductions in
- 39:48drinking or the sustained overtime.
- 39:51As you noted,
- 39:52I'm sure that there were challenges
- 39:53both with recruitment and drop out.
- 39:55We were able to recruit about
- 39:57half of the sample that we had
- 39:59hoped to get for this trial,
- 40:01so we were underpowered
- 40:03to detect differences.
- 40:04We had stricter entry criteria than
- 40:06many such studies which may have
- 40:07affected our ability to recruit people.
- 40:09Had to have an active alcohol use disorder.
- 40:11They had to have recent drinking and
- 40:13they had to have full criteria for PTSD.
- 40:16We should not take some threshold
- 40:18for this study.
- 40:19Then people had to be willing to treat
- 40:22either disorder or wait for care.
- 40:24We also found that some people had
- 40:26already reduced their drinking by baseline.
- 40:27They were primed and ready to
- 40:29make those changes,
- 40:30and those were folks that we
- 40:32had to take from the trial.
- 40:34And some people anecdotally needed seem
- 40:36to need one treatment or the other.
- 40:38It was very interesting in
- 40:41our consultation calls.
- 40:43Their therapist would sometimes
- 40:44say I wish this person have gotten
- 40:46randomized to the other condition,
- 40:48and I do think that that begs
- 40:50the question for future research.
- 40:52To really look that treatment matching.
- 40:55Ann about anecdotally,
- 40:55about a third of those assigned
- 40:57to relapse prevention,
- 40:58or disappointed because they wanted
- 41:01to work on the trunick of that.
- 41:04The bigger picture take home
- 41:06messages on PTSD and substance use.
- 41:07Go hand in hand so we gotta figure
- 41:10out how best to treat this.
- 41:12And there is a high burden of disease
- 41:15associated with these disorders.
- 41:16Patients often do have a preference
- 41:19for one treatment versus another.
- 41:22And cognitive trauma focused therapies
- 41:24may have some promise for addressing
- 41:26PTSD and substance use disorders,
- 41:29so they're worth pursuing as an
- 41:31additional option for treatment to
- 41:34increase our our range of interventions
- 41:36over and above some of the non trauma
- 41:39focused therapies and some of the
- 41:41more exposure focused therapies and
- 41:43overall drop that is a problem in this field.
- 41:47So we've gotta find some interventions
- 41:50that are a little more sticky.
- 41:53Or some strategies to help people stay in,
- 41:56especially given some of the findings
- 41:58that we had about dose effects.
- 42:00I would say overall,
- 42:01there's increasing evidence that
- 42:03there is no wrong door for treatment.
- 42:06An providers might be able to have
- 42:08good treatment outcomes on both
- 42:10disorders using high quality,
- 42:12evidence based interventions targeting
- 42:14either PTSD or substance use, or both.
- 42:18And with that.
- 42:20Any questions?
- 42:27Thank you, Deborah.
- 42:29Very, very interesting and
- 42:31important conclusions where you
- 42:34you for your talk and so want to
- 42:37open this up for questions to you.
- 42:40Maybe I can begin with
- 42:43with just the observation.
- 42:45So it suggests that you that that
- 42:48individuals be given a choice of evidence
- 42:52based treatments when they enter.
- 42:54When they have Co occurring PTSD in
- 42:58a substance use disorder and then.
- 43:01Clinicians,
- 43:01are you recommending Christians
- 43:03follow that choice as as long as
- 43:06the treatment is evidence based?
- 43:09I mean, I think that's an empirical question.
- 43:12Right, but I think it's one that we need
- 43:14to ask Lori Zoellner and Orfini have
- 43:17done some really wonderful research
- 43:19looking at the impact of choice on
- 43:21when we give people with PTSD a choice
- 43:23between medication versus psychotherapy.
- 43:25How many choose medication?
- 43:26How many choose psychotherapy and
- 43:28then what's the implication if people
- 43:30don't get what they what they chose?
- 43:32That kind of research has not happened to
- 43:34date as far as I know in the PTSD substance.
- 43:37Do you feel that patients often
- 43:38have an idea or have a preference,
- 43:40and I think that is the next natural step
- 43:42in the field is what would you pick?
- 43:45What do you want to do?
- 43:46And then does that make a difference
- 43:48in how likely you are to stick with it?
- 43:51Right and I can see arguments either way.
- 43:53It may be that the PTSD avoidance
- 43:55is compelling and people say, oh,
- 43:57I don't want to talk about that
- 43:59and maybe those the people actually
- 44:01need a trauma focused therapy.
- 44:03Or it may be that people actually
- 44:05have a good idea about what they're
- 44:07able to do or what pathway to recovery
- 44:10may be most approachable for them.
- 44:13Identification.
- 44:15Hi
- 44:15my name is Sophia and I'm a fourth
- 44:18year psychiatry resident who's really
- 44:19really interested in trauma and PTSD.
- 44:22And I also listen to hear
- 44:24this merican life quadcast,
- 44:25the one with twelve sessions on CPT,
- 44:27which was really,
- 44:28really insightful. Honestly,
- 44:29to hear from a patient's perspective,
- 44:31just going along with choice.
- 44:32I also just wanted to ask you about like
- 44:35group CPT versus 1 to one CPT as well,
- 44:38because you know in groups
- 44:39there's a group stare right?
- 44:41And a lot of group modalities for this,
- 44:43and I guess I'm in my research I I guess I
- 44:47don't have a great sense of like does group.
- 44:51If someone also prefers group like,
- 44:53is it as helpful as one to one?
- 44:56I've also heard that you know a
- 44:58lot of trouble like healing from
- 44:59trauma happens in groups too.
- 45:01When you feel really seen and heard
- 45:02and validated by other people.
- 45:04So I just want to ask your opinion on that.
- 45:07Yeah, I love it and I'm happy to
- 45:09take questions about anything I I am
- 45:12absolutely fearful to talk about any
- 45:14kinds of topics that you're curious about
- 45:17in terms of group versus individual.
- 45:19I have an empirical answer and
- 45:21then I have a broader answer,
- 45:23so there just was a trial.
- 45:25I think they just presented the outcome
- 45:28data relatively recently at IST SS,
- 45:30where they looked at individual
- 45:32versus group CBT.
- 45:33It's actually the first trial that's
- 45:35done that head to head comparison.
- 45:37To answer exactly the kind of questions
- 45:39Sofia that you're bringing on.
- 45:41And what they found was that individual
- 45:44was slightly more effective.
- 45:46And I think there are some reasons for that.
- 45:50With individual therapy,
- 45:51you're getting more airtime for
- 45:53working on your specific stuck points,
- 45:55and the therapist can help guide you.
- 45:58If you're getting a little bit
- 46:00more avoidant directly,
- 46:02easier to get missed in a group setting.
- 46:05Now.
- 46:05That being said,
- 46:06I think for some clients group is an
- 46:09incredibly powerful way of recovering.
- 46:14Asians? Sometimes listen to each other
- 46:16much more deeply than they listen to us.
- 46:19People have had the same to
- 46:21live the experiences of them,
- 46:23and it's also great for them to
- 46:25get to be in the healer mode.
- 46:28In Congo, CPT was delivered
- 46:30entirely by group and it was
- 46:33wonderful hearing our group members
- 46:36have to meet other staff points.
- 46:41And that's a way of learning and
- 46:43we learn through teaching, right?
- 46:44And so that's also a very
- 46:46powerful kind of learning.
- 46:47The other thing that's great about great,
- 46:49this is cost effective.
- 46:51Right, so you know if
- 46:53you have two therapists,
- 46:54an 8 people in a group as a whole
- 46:56lot more people in two hours
- 46:58than you would do with everybody
- 47:01seeing them individually.
- 47:05Thank you. Muscle. I
- 47:08wonder Doctor case and if the
- 47:10combination of both wouldn't
- 47:12be really effective, you know?
- 47:14I mean, for the person who
- 47:16wants the mutual support,
- 47:17maybe you start with group and
- 47:20you don't get into the intensive.
- 47:22Trauma is much,
- 47:24but you gain the coping skills.
- 47:26You know that can help you
- 47:29address it in a deeper way,
- 47:31or vice versa for someone who
- 47:33doesn't want to expose themselves
- 47:34to a group experience because
- 47:36of their shame and other issues
- 47:38around the trauma you know.
- 47:40And they do that.
- 47:41And then with some confidence can
- 47:43go into the group and gain that
- 47:45mutual support that will really
- 47:47reinforce 'cause as we know, PTSD.
- 47:49And you know the trauma.
- 47:51It takes a long time to heal.
- 47:53It's not going to be just one session of IOP,
- 47:55or you know.
- 47:57You know that's going to help them,
- 47:59and that's going to be a done deal.
- 48:01Damn you are so wise and I absolutely
- 48:04agree with what you're saying.
- 48:06And there is some great work
- 48:08that's being done.
- 48:09For example,
- 48:09it's rubbish.
- 48:10They have a two week that that like
- 48:13so when people talk about like
- 48:15what's an advance in the field,
- 48:17you're super excited about this program.
- 48:19I am over the moon with.
- 48:21I think it's so cool and Pam it
- 48:23comes in with some of the types of
- 48:25ideas that you're talking about.
- 48:27It's mask treatment,
- 48:28so it's intensive outpatient program.
- 48:30It's it is not for comorbid, it is for PTSD.
- 48:35People can have comorbidities,
- 48:36but it's not focused on PTSD alcohol use,
- 48:39but people get daily CPT for two weeks.
- 48:43And they get both group an individual.
- 48:47And the results they're getting.
- 48:49It's for active duty military or veterans.
- 48:52The results they're getting in an
- 48:55active duty and veteran population
- 48:57look like civilian samples.
- 48:59Typically we get smaller effect sizes,
- 49:02smaller benefits from treatment
- 49:05when we have military members.
- 49:08And So what they're getting with
- 49:10doing that kind of intensive
- 49:12treatment is very low dropout,
- 49:14less than 10%,
- 49:16and huge treatment gains in two weeks.
- 49:20I think that's just fabulous,
- 49:21but I also think that that combination
- 49:23of individual and group helps.
- 49:24I see that Deborah has a hand up number.
- 49:27You are much more polite than me.
- 49:29I'm a jumping in person,
- 49:30but I want to reinforce lovely day of yours.
- 49:34Oh, you're muted though.
- 49:38Forgive me if you addressed this,
- 49:40but how do you rate EMDR with
- 49:42CPT in the other interventions?
- 49:44'cause I know in this community
- 49:46I often I'm working with someone
- 49:48who's had trauma and I'm a dynamic,
- 49:51is psychiatrist, and I do can calm and
- 49:54send them to someone who does EMDR.
- 49:57But I don't know the outcome
- 49:59literature and comparatively with CPT,
- 50:01so that'd
- 50:02be great. Thanks.
- 50:03Yeah, I'm happy to talk to that.
- 50:06There are no EMDR to CPT
- 50:08head to head comparisons,
- 50:09so I can't directly speak to,
- 50:12you know, if there was a horse race,
- 50:15I would they do what I can say is ISTSS just
- 50:19did a comprehensive analysis of the data.
- 50:22It was beautifully done, project all
- 50:24of the questions were preregistered.
- 50:27We had people from all of the different
- 50:30therapies represented as people approached.
- 50:32Looking at the literature and the
- 50:34three therapies that got our sort of
- 50:36strongest recommendation in terms of
- 50:38the strength of the literature work,
- 50:40a long exposure.
- 50:42CPT and EMDR,
- 50:43and so it is a I don't do
- 50:45EMDR not trained in it,
- 50:48but it is a therapy that I feel very
- 50:51comfortable referring people to because
- 50:53it is an effective therapy as well.
- 50:59Did that answer your question, Deborah?
- 51:02Yes, now if we're going back to the
- 51:04issue about comorbidity though,
- 51:06I don't know of any child's that
- 51:08have looked at EMDR for PTSD,
- 51:11substance use comorbidity,
- 51:12so I think that's an open question.
- 51:14We know PE works right,
- 51:16and we know that cope,
- 51:18which is PE overlaid with
- 51:20substance use treatment works.
- 51:22And we know that CPT works,
- 51:23but I don't know about EMDR because
- 51:25the studies haven't been done.
- 51:29Doctor Kayson yeah can I ask you another
- 51:32question about like Centers of excellence? I
- 51:34am all yours, I'm all yours.
- 51:36Thank you. Appreciate it.
- 51:39So you know I've been trying to find
- 51:42like centers of excellence for PTSD care
- 51:44that they are outside of the VA and
- 51:46like it for civilians instead of vets.
- 51:48'cause you mentioned it like an
- 51:50example of our really awesome,
- 51:51more intensive like IOP sort of program
- 51:54for that are that is still for vets
- 51:56like I know about like you know the
- 51:58Trauma Recovery Center at UCSF but
- 52:00like are there that many programs out
- 52:02there that provide different types of
- 52:04like choice in PTSD care and multiple
- 52:06types of treatments for civilians.
- 52:08Yeah, so so here this is actually
- 52:11in many ways mild life mission,
- 52:14which is that we've done an outstanding
- 52:17job disseminating therapies for
- 52:19PTSD for our service members.
- 52:21And there are so many people have
- 52:24experienced these types of events.
- 52:27Who are not service members and for them
- 52:30getting good care is really murdered.
- 52:34What I can tell you is,
- 52:35so there are definitely some places
- 52:37Emory's got a wonderful clinic.
- 52:38Um, so I would put Emory on that list.
- 52:42You're exactly right.
- 52:43UCSF does a beautiful job and then
- 52:46you can find individual places,
- 52:48but it's there isn't like a network.
- 52:50So for example, and I know a lot
- 52:53of Washington state resources,
- 52:55'cause that's where I was for 17 years case.
- 52:59ARC is the King County sexual assault,
- 53:01something something?
- 53:02There are wonderful program.
- 53:04They provide either sliding fee or free QR
- 53:07for sexual assault survivors in King County.
- 53:10Whole age range from 6 to whatever
- 53:12and they provide various treatments.
- 53:14The Harborview Center for Sexual
- 53:16Assault and Traumatic Stress,
- 53:17so you'll find these places.
- 53:19Stanford now has started up
- 53:21a PTSD clinic where we have a
- 53:23whole variety of interventions,
- 53:25but the problem is,
- 53:26is that enough time?
- 53:27There isn't a great network.
- 53:30Around centers of excellence
- 53:31as you're talking about,
- 53:32so I hope you maybe pick that
- 53:34up as your mission in life.
- 53:37Thanks, Patrick. Listen I'm
- 53:38going to send you an email if you
- 53:40don't mind about this. 'cause
- 53:41I got really obsessed but I don't mind
- 53:43at all and and you can feel free to
- 53:44nag me 'cause periodically my inbox
- 53:46becomes something that is aversive.
- 53:48And so if I don't respond right away.
- 53:51Von, it looks like you've got
- 53:53a question. I think that's great talk.
- 53:56I think understanding the
- 53:58overlap with comorbidities,
- 53:59especially in substance use
- 54:00disorders not well understood.
- 54:02So it's really good to see the overlap
- 54:05and trying to tease them apart,
- 54:07and that more treatment in
- 54:09general is effective.
- 54:10I'm I'm curious if you have
- 54:12thoughts on on two topics.
- 54:14One, what brain functions do you think
- 54:17are changing with your interventions
- 54:19and are they similar and different
- 54:21that are driving PTSD and Sud?
- 54:24Improvement and then with the
- 54:25comorbidities of PTSD and STD and the
- 54:28use of transcranial magnetic stimulation
- 54:30to treat either of those diseases.
- 54:32What are your thoughts on maybe
- 54:34adding TMS as an add event to
- 54:36your ongoing interview base or
- 54:38or group based interventions?
- 54:40And you think that might so
- 54:42for your first question,
- 54:44what
- 54:44I will say is I am far more
- 54:46of a public health community.
- 54:49Health services kind of researcher,
- 54:51so I leave the neurobiology to
- 54:54people who are smarter than me.
- 54:56So I have no idea I'd have to go
- 54:58and delve and really think about
- 55:00what we think are mechanisms.
- 55:02I'm a mentor right now on a K,
- 55:04where I'm hoping that that person
- 55:06will be the person to help me figure
- 55:08that out during these treatments.
- 55:09Brilliant scientist is a mechanical engineer
- 55:11who is now interested in our science.
- 55:13I hope the grant funds.
- 55:15Um, in terms of the transcranial
- 55:17magnetic stimulation,
- 55:18that is a really exciting direction.
- 55:20I think in the field there is a study
- 55:22that is going on right now that's looking
- 55:25at that combined with CPT just for PTSD,
- 55:28so we'll find out soon whether we
- 55:30get additive effects with that.
- 55:32So I can say that you're thinking
- 55:34right in the same lines as some
- 55:37of the other people in this field
- 55:39when we add in the substance use,
- 55:42I think that's a really interesting question,
- 55:44especially with.
- 55:45High rates of drop out of can we
- 55:47get people better a little faster?
- 55:49Maybe that'll make it easier for people
- 55:51to stick with the therapies as well.
- 55:53Good question thanks.
- 55:54I look
- 55:54forward to seeing the
- 55:56results of that. Yeah, yeah,
- 55:57keep an eye out.
- 56:00Labria I gotta question in the chat.
- 56:04That was sent to me.
- 56:06Person was intrigued by the use
- 56:07of CPR in the development of the
- 56:09trial for American Indian for
- 56:11the American Indian community.
- 56:13You described.
- 56:14What do you think would was the
- 56:16impact of allowing the community
- 56:18to choose the intervention?
- 56:19And how do you think CPR can
- 56:21continue to inform work with
- 56:23this population and with others?
- 56:26Yeah, absolutely.
- 56:26It's a wonderful question,
- 56:28so let me talk a little bit about that
- 56:30relationship with this particular tribe,
- 56:32'cause they think it's really
- 56:34important to talk about. So.
- 56:36The tribe had actually approached
- 56:39University of Washington long
- 56:41before this trial was begun.
- 56:44An I think it's important that this
- 56:46trial was not investigator initiated.
- 56:48It wasn't us with our idea
- 56:50about how to help people.
- 56:52Coming to a community,
- 56:54but it was actually the community asked,
- 56:57asking to partner with us and then us
- 57:00together coming up with a solution.
- 57:02But that man is we actually had
- 57:05quite a bit of Community client.
- 57:09And they felt like they had a
- 57:11voice in the whole process.
- 57:12This the data belongs to the tribe.
- 57:15The data for this project isn't ours.
- 57:17It's not the investigators.
- 57:20That helped quite a bit with recruitment,
- 57:22but it also helped with
- 57:24the adaptation process,
- 57:25so we had tribal elders.
- 57:26We had Native American clinicians
- 57:28who all helped with the development
- 57:30of the adapted materials.
- 57:31An example I wish I had a slide to show you.
- 57:35So for those of you who are familiar
- 57:37with the worksheets in CBT or other
- 57:40cognitive behavioral therapy is right.
- 57:42So we've got this worksheet that's got
- 57:44these columns on it an A lot of text,
- 57:47right?
- 57:49When the community reworked the worksheet
- 57:52an away where it was overlaid over
- 57:55a picture of a mountain and rather
- 57:58than a left to right processing,
- 58:00it actually was going from bottom
- 58:02to top 'cause you're climbing the
- 58:05mountain to get to the adapted thought.
- 58:08I hate that worksheet it makes my brain
- 58:11hurts however it was so fascinating
- 58:13presenting that worksheet to our therapist,
- 58:16some of whom were Native American
- 58:18and some of whom were not.
- 58:21And our clinicians,
- 58:23who are Native American more like.
- 58:26Yeah, that finally makes sense for me.
- 58:29And so I do think we can get things that
- 58:33resonate better for a community when
- 58:35we listen because we are academics.
- 58:38We know lots of things,
- 58:40but we don't know all the things.
- 58:44And so that part is important.
- 58:47If we have time,
- 58:48I can talk to you about a project
- 58:50that Lori's owners doing,
- 58:52partnering with a samale community,
- 58:54which I think is one of the most
- 58:56elegant examples of a culturally
- 58:58adapted PTSD therapy I've ever seen,
- 59:00and it really came out of that
- 59:02CPR concept and listening to the
- 59:04Community and then bringing our
- 59:06knowledge to the table.
- 59:08But welding it with what the community knows.
- 59:13Thank you Deborah.
- 59:14I just wanna follow up.
- 59:16There was another question
- 59:18that was sent to me separately
- 59:20which was give a sense of the
- 59:23differential influence of CBT
- 59:25CPT on PTSD symptom clusters
- 59:27and ultimately substance use.
- 59:30That's a fantastic question.
- 59:31We have not analyzed that data yet,
- 59:34but we definitely will.
- 59:35I am also very curious of where is
- 59:39it that we're seeing the changes?
- 59:41Is it? Is it that we're pushing
- 59:44down on avoidance, right?
- 59:45That's a possibility.
- 59:46Is it that we're shifting hyperarousal?
- 59:49Are there particular clusters that are more
- 59:52predictive of changes in substance use on?
- 59:54There are studies that are more launch
- 59:57tunele studies looking at which PTSD
- 60:00symptom clusters seem to be most associated.
- 01:00:02With substance use,
- 01:00:03but the data is all over the place.
- 01:00:06Some studies find that it's
- 01:00:08driven by true symptoms.
- 01:00:09Some studies sign that
- 01:00:10is driven by avoidance.
- 01:00:12The findings are super inconclusive,
- 01:00:13and so I think looking at a cognitive
- 01:00:16intervention and what do we see
- 01:00:18changes and predicts change in
- 01:00:19substance use would be fascinating,
- 01:00:21and we have that data daily level.
- 01:00:24Right,
- 01:00:25so we'll actually be able to look at it.
- 01:00:28Overtime over the course of therapy.
- 01:00:31Deborah,
- 01:00:31this is Tami sold and that was
- 01:00:34actually my question and I'm curious
- 01:00:36to know what your thoughts are about
- 01:00:38symptom clusters in the relationships
- 01:00:40of from PTSD to substance use
- 01:00:42being different by population,
- 01:00:43and I referenced traumatic events so
- 01:00:45those who have experienced sexual
- 01:00:47assault versus partner violence.
- 01:00:49And of course people who experience
- 01:00:51one type of trauma tend to
- 01:00:53experience many types of trauma,
- 01:00:55but I wonder if you have
- 01:00:57any thoughts about that.
- 01:00:59Yeah, well, we didn't see that.
- 01:01:02You know,
- 01:01:03I know the daily data pretty well
- 01:01:05because one of my studies was any.
- 01:01:07I'm a study with college women had
- 01:01:09experienced sexual assault and it
- 01:01:11was one of the first studies that
- 01:01:13actually tried to breakdown at a daily level.
- 01:01:15What do we see with specific
- 01:01:17symptoms of PTSD?
- 01:01:18So we did a factor analysis and then
- 01:01:21we looked at what predicted drinking.
- 01:01:23And you know what we found was
- 01:01:26not entirely what we expected.
- 01:01:28Tammy was.
- 01:01:28So what we found was that there were
- 01:01:31very specific symptoms of PTSD.
- 01:01:33There were,
- 01:01:34so she would hide higher drinking
- 01:01:36in that population.
- 01:01:37So we found that it was more the
- 01:01:40like Hyperarousal and a little bit of
- 01:01:43the intrusive symptoms that predicted it.
- 01:01:45But we found that other symptoms of PTSD
- 01:01:48were associated with lower drinking,
- 01:01:50so the more dysphoric symptoms of PTSD.
- 01:01:53Predicted lower drinking on a given day.
- 01:01:56What was also interesting in that
- 01:01:58study that I think the field
- 01:02:00hasn't played with enough,
- 01:02:02is that we didn't find it at a
- 01:02:05between persons level of analysis.
- 01:02:07We found it on a within person's
- 01:02:10level of analysis.
- 01:02:11So what I mean by that is it wasn't
- 01:02:13so important whether my hyperarousal
- 01:02:16intrusive symptoms were higher than yours.
- 01:02:19It was if my intrusive symptoms
- 01:02:21are higher for me than my average.
- 01:02:24I am more likely to drink on that day.
- 01:02:28Write an I am likely to drink more.
- 01:02:31For last, if it was a dysphoric symptom,
- 01:02:35and so I do think that question
- 01:02:37of the person's
- 01:02:38own individual mean their own individual
- 01:02:42baseline is an interesting one.
- 01:02:44Now when we look across populations,
- 01:02:47you know so much of this work
- 01:02:50has been done in veterans.
- 01:02:53But I do think that we likely have
- 01:02:56slightly different presentations
- 01:02:57and a veteran sample, for example,
- 01:03:01than sexual assaults in full.
- 01:03:04In terms of both,
- 01:03:05what PTSD symptoms may be most
- 01:03:07prevalent and which ones may be
- 01:03:10more associated with drinking?
- 01:03:11If I can rip off of that
- 01:03:14actually as well family,
- 01:03:15the other thing that the field
- 01:03:18doesn't talk about very much is where
- 01:03:21is the person in terms of force.
- 01:03:23How long have these
- 01:03:26behaviors been associated?
- 01:03:27Right, so the college women have
- 01:03:31had those associations in theory
- 01:03:33for a shorter period of time.
- 01:03:36In that that data that I presented
- 01:03:39the R 21 that Tracy and I worked on.
- 01:03:43You know we looked at different
- 01:03:45motives for drinking and that was one.
- 01:03:48For example,
- 01:03:49we saw real relationships for
- 01:03:51enhancement motives, right?
- 01:03:52I drink because I'm trying to
- 01:03:55feel something which we don't
- 01:03:57talk about very much.
- 01:03:58We talk about coping motives.
- 01:04:01And I think that's something
- 01:04:04we're going to be more likely
- 01:04:07to see in a Masonic stamp.
- 01:04:10With the college women we saw lots
- 01:04:13of celebratory social drinking.
- 01:04:14As well as coping drinking.
- 01:04:16So for them we saw both and
- 01:04:18we've seen that pattern as well
- 01:04:19to longitudinal study of young
- 01:04:21lesbian and BI women where we
- 01:04:23see that pattern sometimes.
- 01:04:24I'm just drinking to have fun with
- 01:04:26friends and then sometimes I'm
- 01:04:28drinking to manage my symptoms.
- 01:04:30That was a really long answer.
- 01:04:32I'm
- 01:04:32sorry Tammy. No no,
- 01:04:34that was a great answer. And
- 01:04:36Interestingly, we actually just looked
- 01:04:38at the Association of PTSD and smoking
- 01:04:40among women who are experiencing
- 01:04:42partner violence and found the same.
- 01:04:44It was stimulation and state
- 01:04:45enhancement is associated with smoking.
- 01:04:47No, that wasn't. If you do,
- 01:04:49you want me to send you that paper
- 01:04:51where Tracy and I looked at the
- 01:04:54enhancement motives and drinking?
- 01:04:59Sounds like she said
- 01:05:00yes sorry. Sure yes, yes, yes they do.
- 01:05:03You have to say yes, you
- 01:05:05won't hurt my feelings.
- 01:05:06I'm always pleasantly
- 01:05:07surprised when someone read
- 01:05:08something I wrote. I was on
- 01:05:10mute. Yes, Please remember.
- 01:05:12There's a ton of go ahead.
- 01:05:14There's a general question in the
- 01:05:16chat that I wanted to ask you,
- 01:05:18someone, someone asked,
- 01:05:19did you look at patients with
- 01:05:21service connection pending?
- 01:05:22And whether that was correlated
- 01:05:24to drop out or outcome?
- 01:05:27Yeah, no, that's an incredible question.
- 01:05:29So because the study was not
- 01:05:32at VA per Southeast study,
- 01:05:34we did not collect data in this
- 01:05:36study on service connection.
- 01:05:38So we ask people if they
- 01:05:40were of actions or not,
- 01:05:42but it wasn't sort of an official VA study.
- 01:05:46So the way the veteran piece went is
- 01:05:50patients could choose if they wanted
- 01:05:52to be seen at the VA or at the clinic.
- 01:05:56That was up to them.
- 01:05:58If somebody identified as a veteran,
- 01:06:00they automatically went to the
- 01:06:02VA to get their their sessions,
- 01:06:04but everyone else could just kind of
- 01:06:06pick what was more convenient for them.
- 01:06:09Um, and so the focus of this was,
- 01:06:11I think, less veteran oriented than
- 01:06:14if it had been more of a VA study,
- 01:06:17so I don't have that data for you.
- 01:06:19It's a great question.
- 01:06:26Other questions for Deborah.
- 01:06:33Doctor case and I just wanted to
- 01:06:34know is it and I don't even know
- 01:06:37if this is inappropriate to ask,
- 01:06:38but is it possible for
- 01:06:40us to have a copy of your
- 01:06:43of your presentation?
- 01:06:44I just want notes fast enough an
- 01:06:46you know, so that's my thing.
- 01:06:50Yeah no, no worries Pam, no worries.
- 01:06:52Usually we have the talk has been
- 01:06:55recorded and so it'll be available.
- 01:06:57Trisha and should be the following
- 01:06:59week, right? Is that the
- 01:07:01case? Yes, it should be available
- 01:07:03early next week on the Department
- 01:07:05of Psychiatry Grand Rounds website.
- 01:07:09Great project. No problem.
- 01:07:14Other questions or comments?
- 01:07:17Mary
- 01:07:19environment. I was quite taken
- 01:07:23by the story of the mountain and
- 01:07:26going from the bottom to the top,
- 01:07:29that East communication with
- 01:07:31the native Indians and it kind
- 01:07:34of brought into my memory at.
- 01:07:38An moment when I was considering
- 01:07:42to go to work in Africa with
- 01:07:44dramatized situation estimate,
- 01:07:46traumatized population,
- 01:07:47and at that time I had a friend who was.
- 01:07:52She's a black lady and
- 01:07:55she was here Adele studying
- 01:07:58African American arts.
- 01:08:00And I was talking to her about art therapy.
- 01:08:05I'm quite naive in it and her
- 01:08:09immediate reaction was up struct
- 01:08:11art. And kind of surprised, maybe because.
- 01:08:17Yeah, it just didn't expect it.
- 01:08:19You know that her immediate very
- 01:08:21quick reaction was that this is
- 01:08:24much more close to
- 01:08:26the heart of black people, and
- 01:08:28I was wondering, you know whether?
- 01:08:32Different art techniques
- 01:08:34are used in communications
- 01:08:36with different populations.
- 01:08:38Here in States and may
- 01:08:41do in treatment in PTSD.
- 01:08:46Yeah, so that's out that would be
- 01:08:48outside of my area of expertise and
- 01:08:50what I can tell you is the data around
- 01:08:54art therapy for PTSD has generally
- 01:08:56not found that it is effective,
- 01:08:58at least in reducing PTSD symptoms.
- 01:09:00Now that's not to say it can't work
- 01:09:03for somebody, or that it might not be
- 01:09:06a good adjunct to treatment, right?
- 01:09:08So you could think about that
- 01:09:10as a way of engaging someone,
- 01:09:12but then coupling it with one
- 01:09:14of these therapies for people.
- 01:09:16Focus on the trauma itself,
- 01:09:18but at least now most of that
- 01:09:20research has been done with children,
- 01:09:23not with adults.
- 01:09:25But in that review of the literature
- 01:09:27that IST SS, did they?
- 01:09:29Did not find that generally art therapy
- 01:09:32was effective for kids in reducing PTSD.
- 01:09:36So I think it's an interesting question.
- 01:09:39I don't know
- 01:09:40that, because yeah, I
- 01:09:42probably didn't didn't even think
- 01:09:44about the treatment of PTSD,
- 01:09:47but more like easing the communication
- 01:09:49as you described, so nicely. Yeah,
- 01:09:53absolutely. I mean,
- 01:09:54I think that's a great question of
- 01:09:57how do we engage people in K, right?
- 01:10:00How do we get people interested
- 01:10:03in the conversation?
- 01:10:04There is an investigator,
- 01:10:06for example, who's working with
- 01:10:08I believe Syrian refugees.
- 01:10:11And he is in Milwaukee if I'm correct
- 01:10:13and he's using yoga and dance as a
- 01:10:16way of engaging the community because
- 01:10:18what he found is they weren't willing
- 01:10:21to come in for these psychotherapies.
- 01:10:23But then once they're coming
- 01:10:25in for yoga and dance,
- 01:10:27then they're getting them
- 01:10:28engaged in the trauma therapies.
- 01:10:32Thank you. Yeah, no
- 01:10:35problem we have. We have time for
- 01:10:38probably one more question or comment.
- 01:10:42Another, any other questions or comments?
- 01:10:52Well, maybe that's a good place to stop.
- 01:10:56Thank you so much Deborah.
- 01:10:58This has been just a terrific
- 01:11:00presentation that you gave and
- 01:11:02also discussion afterwards.
- 01:11:04Really appreciate you doing this.
- 01:11:07Well, I really appreciate the
- 01:11:08invitation and the chance to have
- 01:11:10a conversation with all of you.
- 01:11:11I always leave these kinds of
- 01:11:13talks inspired and with new ideas.
- 01:11:15So for those of you in the audience,
- 01:11:17if you do have questions or
- 01:11:19want articles, let me know.
