Kline AC, Straus E, Lyons RC, et al. - Researchers randomized a total of 119 veterans to receive integrated exposure therapy (Concurrent Treatment of post-traumatic stress disorder [PTSD] and Substance Use Disorders Using Prolonged Exposure; Back et al., 2015) or integrated coping skills therapy (Seeking Safety; Najavits, 2002) in a clinical trial for comorbid PTSD+alcohol use disorder (AUD) (Norman et al., 2019) to evaluate substance use–related predictors of session attendance. The data exhibited that, at the start of therapy, the percentage of abstinence days, AUD duration, and living in a controlled environment (e.g., recovery home) were not correlated with attendance in either treatment condition. As per the findings, only a subset of substance use characteristics predicted attendance. There was no evidence to support the notion that alcohol use leads to lower attendance in exposure therapy in comparison with nonexposure therapy.
