Treatment Goals and Alcohol Use Outcomes in Veterans With Comorbid Alcohol Dependence and Posttraumatic Stress Disorder

Background and Objectives Previous research demonstrates the utility of goals in attaining improved drinking outcomes. Considerably less is known about the association between substance use goals and outcomes among persons with comorbid substance use disorder (SUD) and posttraumatic stress disorder (PTSD). This secondary analysis examined the association between alcohol use outcomes and participants' treatment entry substance use goals to either abstain or reduce substance use in the context of treatment for comorbid SUD/PTSD. Methods Participants (N = 39) were treatment-seeking veterans with current alcohol dependence and PTSD. Participants completed self-report and clinician-rated measures of substance use and PTSD as part of a larger randomized controlled trial. Results Participants in both goal groups (abstain; reduce) achieved significant reductions in the likelihood of drinking and the likelihood of exceeding low-risk drinking levels. The primary analysis did not identify significant differences in outcome between goal groups; however, the exploratory analysis revealed that participants with reduced use goals were more likely to drink and more likely to exceed low-risk drinking levels. Conclusion and Scientific Significance The findings suggest a moderately strong association between substance use goal and drinking outcome in the current study. Although the findings did not unequivocally support abstinence as a superior treatment goal, they offer a preliminary indication that abstinence may be an overall lower-risk option. These findings expand consideration of the utility of substance use goals and suggest that clinicians should invite consideration of abstinence but may need not limit integrated treatment for SUD/PTSD based on strict adherence to abstinence, particularly if low-risk use goals are targeted.
