Funded Activity Summary

The high prevalence of PTSD among people with illicit drug use disorders (IDUD) has been clearly recognised in both the Australian and international literature. In Australia, 33% of those with opioid use disorders and 24% of those with amphetamine use disorders have comorbid PTSD. The prevalence among people with alcohol use disorders on the other hand, is comparably low (5%). Despite the high prevalence of PTSD among people with IDUD, research on treatment responses to this significant problem is sparse. Individuals with this comorbidity present a significant challenge to substance abuse treatment providers as they present with a poorer clinical profile, and have poorer treatment outcomes, including higher readmission rates. Consequently, they are a costly burden to the health care system. The costs of this comorbidity to individual sufferers and society may be reduced substantially by the implementation of an integrated treatment that addresses both disorders concurrently. There is however, little research to guide how best to treat comorbid IDUD and PTSD. Although a small number of interventions have been developed and trialled, none have been evaluated in an Australian setting. One intervention which has shown promise in the United States is Concurrent Treatment of PTSD and Substance Use Disorder (CTPSD). Preliminary research has shown that CTPSD can be used safely and is effective in the treatment of PTSD among individuals with cocaine dependence. Completers of the program have demonstrated significant reductions in all PTSD symptom clusters and cocaine use from baseline to end of treatment which were maintained at 6 month follow-up. Significant reductions in depressive symptoms were also observed. Despite these promising results, CTPSD is yet to undergo a randomised controlled trial. The proposed study is a randomised controlled trial of the efficacy of CTPSD in the Australian setting.
