Research Summary

The goal of my program of research is to refine etiological models of substance use disorders by integrating genetically-informative designs with a developmental psychopathology approach to the study of drug and alcohol use in adolescents and young adults. Much of my research focuses on the progression through stages of substance use (e.g., initiation, onset of symptoms) and the timing of transitions in relation to the onset of psychiatric disorders and trauma exposure. I have a particular interest in the influence of traumatic life events such as childhood sexual abuse on the course of alcohol use in women and have recently expanded my program of research to include the examination of racial/ethnic differences in patterns of substance use in adolescent girls and young women.

Extensive Research Description

My program of research is aimed at characterizing the contribution of various risk and protective factors, including genetic factors, to pathways of substance use and misuse from adolescence to young adulthood, with a particular focus on alcohol use in young women. Taking a developmental psychopathology approach to the study of substance use disorders is key to capturing the dynamic processes that influence their course. I have applied this perspective by studying alcohol and other substance use disorder development with respect to stages of use (e.g., initiation, onset of substance related problems). Much of my work has focused on a rarely studied characteristic of the course of substance use, the rate of progression between stages of use. This phenotype captures an aspect of alcohol and drug use that cannot be gleaned from simply studying influences on whether a given stage of use is reached. For example, early age at first drink is a strong predictor of alcohol use disorder, but early drinkers take longer to transition from first drink to problem drinking than later initiators. <_o3a_p>

A critical component of this line of research that has been largely overlooked is the identification of distinctions by race/ethnicity in both the course of substance use and the risk and protective factors that influence it. Lower rates of use, lower prevalence of problem or habitual use, and later age at initiation of the use of alcohol and cigarettes in African Americans compared to Whites - in spite of the higher rates of exposure to risk factors such as trauma - suggests that etiological models of alcohol and cigarette smoking do not fit as well for African Americans as Whites. The absence of such differences with respect to marijuana use further highlights the need for a more nuanced approach to understanding the development of substance use across racial/ethnic groups, which is essential to developing culturally tailored interventions. Genetics Much of my work on the development of substance use and related problems has made use of twin samples. Studies I have conducted with my colleagues have revealed distinctions in the contribution of heritable influences at various stages of substance use. Initiation of substance use is attributable to a significant degree to environmental influences common to family members (e.g., shared peers, parenting practices). Progression to problem use, by contrast, is influenced in about equal parts by genetics and environmental factors specific to an individual (e.g., traumatic events), with little to no shared environmental contributions. These findings indicate that the course of substance use is more malleable in its early stages and that interventions aimed at disrupting the progression from initiation to pathological alcohol or drug use need to be more tailored to the individual than do early prevention efforts. <_o3a_p>

Trauma My research interests include the association between trauma exposure and substance use disorders, and in particular, the role of childhood sexual abuse in the manifestation of familial risk for alcohol related problems in women. Rates of childhood sexual abuse are elevated in offspring of alcoholic parents, likely due to characteristics of the alcoholic family environment such as poor parental supervision. Adolescent girls and young women with a history of sexual abuse have often been exposed to a constellation of risk factors, such as parental separation and trauma-related psychopathology (e.g., PTSD, depression) in addition to genetic risk for alcohol use disorders. Disentangling this complex pathway is an important step toward reducing risk for substance use disorders in this high-risk population.
