A Randomized Trial of Concurrent Treatment for PTSD and Substance Dependence

This treatment intervention trial is designed for men and women with substance dependence
and comorbid Post-Traumatic Stress Disorder (PTSD). Participants will be randomly assigned
to one of three conditions (two behavioral treatments [Concurrent Treatment of PTSD and
Substance Dependence and Relapse Prevention Therapy] and a delayed treatment control group)
and will be evaluated at baseline and four follow-up points (post-treatment, 1-month, 2-
month and 3-month post-treatment).

This study will enhance the knowledge and understanding of concurrently treating individuals
with substance use disorders and PTSD in hopes of facilitating treatment retention and
increasing the likelihood for more positive treatment outcomes. Following NIDA's stage model
for behavior therapies development, this study will take the next step building upon
promising findings from Stage IA work with an exposure-based therapy modified to use safely
with substance dependent individuals.

This study is a randomized clinical trial to assess the relative efficacy of two active
treatment conditions versus a delayed treatment control group for substance dependent
individuals who also meet criteria for current PTSD according to the diagnostic standards
set by the DSM-IV. Eligible participants will be randomly assigned to either: (1) Concurrent
Treatment of PTSD and Substance Dependence (CTPSD); (2) Relapse Prevention Treatment (RPT)
or a (3) Delayed Treatment Control Group (DTCG). The study is a three armed randomized
controlled trial with repeated outcome measures at post treatment and 1-,2-, and 3-months
post-treatment follow-up points.
