Abstract
The aim of this study was to test whether the efficacy of in-person and computer delivered brief alcohol intervention (BAI) is moderated by mental health status. General hospital inpatients with at-risk alcohol use aged 18 to 64 years (N = 961, 75% men) were allocated to in-person BAI, computer-based BAI, and assessment only. In-person BAI contained counseling by research staff. Computer-based BAI contained computer-generated individualized feedback letters. BAIs were designed to be delivered at baseline and 1 and 3 months later. Outcome was reduction in alcohol use per day after 6, 12, 18, and 24 months. Latent growth curve models were estimated. Two mental health indicators, the 5-item mental health inventory and routine care diagnosis of mental and behavioral disorders assessed by general hospital physicians, were tested as moderators of BAI efficacy. In all groups, inpatients with better mental health reduced alcohol use after hospitalization (ps < 0.01). While inpatients with impaired mental health did not reduce their drinking significantly following assessment only, those who received any of the 2 BAIs did (ps < 0.05). BAI was particularly efficacious in reducing alcohol use among general hospital inpatients with at-risk alcohol use and impaired mental health, with computer-based delivery being at least as efficacious as in-person delivery.
