Abstract

Background: Individuals with comorbid substance use and posttraumatic stress disorder may differentially benefit from integrated trauma-focused interventions based on specific presenting characteristics such as substance use type and PTSD severity. The current study is a secondary analysis of a NIDA Clinical Trials Network study exploring the effectiveness of two interventions for women with comorbid PTSD and substance use disorders. Method: Generalized estimating equations were used to examine the association of baseline alcohol misuse with PTSD outcome measures over time for all randomized participants. Results: Women entering treatment with baseline alcohol misuse had higher Post Traumatic Stress Disorder Symptom Scale (PSS-SR) total scores (t=2.43, p<.05), cluster C (avoidance/numbing) scores (t=2.63, p<.01), and cluster D (hyper-arousal) scores (t=2.31, p<.05). For women with alcohol misuse, after treatment week 1, PSS-SR scores were significantly lower in the Seeking Safety intervention during treatment (χ2(1)=4.00, p<.05) and follow-up (χ2(1)=4.87, p<.05) compared to those in the health education intervention. Alcohol misusers in the Seeking Safety group who had higher baseline hyper-arousal severity improved more quickly than those with lower baseline hyper-arousal severity during treatment (χ2(1)=4.06, p<.05). Conclusions: These findings suggest that the type of substance abuse at treatment entry may inform treatment selection, predict treatment response among those with co-occurring PTSD and substance use disorders, and indicate a more severe clinical picture.
