Overview
"Risk and Resilience Factors in Iraq Combat Veterans" - This study aims to improve understanding of the needs, symptoms, and strengths of Connecticut OIF/OEF Veterans.
"Mental Health, Resilience, and Soldier's Perceptions about Psychotherapy, Medication, and Barriers to Care in the U.S. Military" - This study aims to determine characteristics that differentiate symptomatic soldiers who seek mental health treatment and symptomatic soldiers who do not seek professional mental health treatment.
"National Health and Resilience in Veterans Study" - The purpose of this NCPTSD-funded study is to characterize genetic, environmental, and gene x environmental determinants of longitudinal trajectories of posttraumatic stress disorder and related mental health outcomes in a nationally representative sample of U.S. veterans.
"Trajectories of Psychological Risk and Resilience in World Trade Center Responders" - This CDC/NIOSH-funded study aims to characterize the nature and correlates of trajectories of posttraumatic stress symptoms of a large cohort of World Trade Center responders.
"Biomarkers of Psychological Risk and Resilience in World Trade Center Responders" - This CDC/NIOSH-funded study aims to examine genetic, epigenetic, and neuroendocrine factors associated with posttraumatic stress disorder in World Trade Center responders.
