Resumen

Objective: A common concern is whether individuals with posttraumatic stress disorder (PTSD) and hazardous drinking will respond to PTSD treatment or need a higher dose. In a sample of active-duty military, we examined the impact of hazardous drinking on cognitive processing therapy (CPT) outcomes and whether number of sessions to reach good end-state or dropout differed by drinking status.Method: Participants included 127 service members participating in a clinical trial of variable-length CPT. The Quick Drinking Screen was used to characterize drinking. Participants were categorized as treatment responders when they reached good end-state (,20 on the PTSD Checklist for DSM–5) or nonresponders if they completed 24 sessions or 18 weeks of treatment without good end-state. Survival analyses were used to compare time to dropout or good end-state between those with and without hazardous drinking. Results: Those with hazardous drinking were as likely as those without to reach good end-state and no more likely to drop out. There were no differences in number of sessions to reach good end-state or dropout. On a gold-standard assessment, those with hazardous drinking evidenced more PTSD symptom reduction than those without. The overall proportion of participants with hazardous drinking decreased (30.7% to 18.6%), as did mean number of drinks per drinking day and drinks on the heaviest drinking day among those initially drinking hazardously.
