Clinical Trial Summary

This project is the first to use a clinical laboratory method in emerging adults to test the hypothesis that a trauma history with or without concommitant posttraumatic stress disorder (PTSD) alters response to a stressor and promotes drinking compared to normal controls. The study will be the first to explore whether trauma-exposed (TE) and PTSD groups differ on these outcomes. It will also examine the relationship between stress reactivity and subsequent stress-induced drinking in these samples. The goal of this program is to better understand the relationship between stress and factors related to the development and maintenance of alcohol problems in early adults, so that ultimately, better treatments may be developed that reduce the incidence and severity of alcohol related problems.

Description:

This study will be conducted with a 3 x 2 between subjects design. The between groups factors are (1) trauma group (3 levels: Control, Trauma Exposed with, and without PTSD) and (2) exposure to stress (2 levels: yes and no). To decrease intra-group variability, trauma type will be limited to interpersonal trauma. Potential participants will be screened over the phone. Those meeting basic eligibility criteria will complete an assessment at the MUSC Institute of Psychiatry, and those meeting final eligibility criteria will be scheduled for the laboratory session to be completed at the Clinical and Translational Research Center (CTRC).

Half of each trauma history group will receive the Trier Social Stress Test (TSST); the other half will receive a no-stress control condition. Baseline and post-stress objective and subjective measures of stress reactivity will be collected. Following the stress task, all participants will be given a priming dose and subsequently presented with an alcohol taste test. The primary analyses will examine the effect of trauma group membership on response to stress and subsequent voluntary drinking. Based on power analyses using preliminary data from similar samples, a sample size of 240 participants (40 per cell) is required.

Intervention

Behavioral:
• Trier Social Stress Test (TSST)
The TSST is a standardized psychological stress challenge where a participant performs a speech and mental math task in front of 3 unfamiliar individuals, in order to evoke an HPA axis stress response in a laboratory setting.

Other:
• No stress condition
