Randomized Trial of Computerized Cognitive Behavioral Therapy for Alcohol Use Disorders: Efficacy as a Virtual Stand-Alone and Treatment Add-On Compared with Standard Outpatient Treatment.

Background Cognitive behavioral therapy ( CBT) is an evidence-based treatment for alcohol use disorders ( AUDs), yet is rarely implemented with high fidelity in clinical practice. Computer-based delivery of CBT offers the potential to address dissemination challenges, but to date there have been no evaluations of a web-based CBT program for alcohol use within a clinical sample. Methods This study randomized treatment-seeking individuals with a current AUD to 1 of 3 treatments at a community outpatient facility: (i) standard treatment as usual ( TAU); (ii) TAU plus on-site access to a computerized CBT targeting alcohol use ( TAU + CBT4 CBT); or (iii) CBT4 CBT plus brief weekly clinical monitoring ( CBT4 CBT + monitoring). Participant alcohol use was assessed weekly during an 8-week treatment period, as well as 1, 3, and 6 months after treatment. Results Sixty-eight individuals (65% male; 54% African American) were randomized ( TAU = 22; TAU + CBT4 CBT = 22; CBT4 CBT + monitoring = 24). There were significantly higher rates of treatment completion among participants assigned to 1 of the CBT4 CBT conditions compared to TAU (Wald = 6.86, p < 0.01). Significant reductions in alcohol use were found across all conditions within treatment, with participants assigned to TAU + CBT4 CBT demonstrating greater increases in percentage of days abstinent ( PDA) compared to TAU, t(536.4) = 2.68, p < 0.01, d = 0.71, 95% CI (0.60, 3.91), for the full sample. Preliminary findings suggest the estimated costs of all self-reported AUD-related services utilized by participants were considerably lower for those assigned to CBT4 CBT conditions compared to TAU, both within treatment and during follow-up. Conclusions This trial demonstrated the safety, feasibility, and preliminary efficacy of web-based CBT4 CBT targeting alcohol use. CBT4 CBT was superior to TAU at increasing PDA when delivered as an add-on, and it was not significantly different from TAU or TAU + CBT4 CBT when delivered with clinical monitoring only.
