Objective-Evaluate moderators and mediators of brief alcohol interventions conducted in the Emergency Department. (18-24 years; N = 172) in an Emergency Department received a motivational interview with personalized feedback (MI) or feedback only (FO), with 1-and 3-month booster sessions and 6-and 12-month follow ups. Gender, alcohol status/severity group (ALC+ Only, AUDIT+ Only, ALC+/AUDIT+), attribution of alcohol in the medical event, aversiveness of the event, perceived seriousness of the event, and baseline readiness to change alcohol use were evaluated as moderators of intervention efficacy. Readiness to change also was evaluated as a mediator of intervention efficacy, as were perceived risks/benefits of alcohol use, self-efficacy, and alcohol treatment seeking.
Methods-PatientsResults-Alcohol status, attribution, and readiness moderated intervention effects such that patients who had not been drinking prior to their medical event, those who had low or medium attribution for alcohol in the event, and those who had low or medium readiness to change showed lower alcohol use 12 months after receiving MI compared to FO. In the AUDIT+ Only group those who received MI showed lower rates of alcohol-related injury at follow up than those who received FO. Patients who had been drinking prior to their precipitating event did not show different outcomes in the two interventions, regardless of AUDIT status. Gender did not moderate intervention efficacy and no significant mediation was found.Conclusions-Findings may help practitioners target patients for whom brief interventions will be most effective. More research is needed to understand how brief interventions transmit their effects.

NIH-PA Author ManuscriptMales and younger patients are more likely to have been drinking prior to treatment in an ED (3), and patients who are admitted to a trauma center with positive toxicology findings have twice the subsequent injury mortality rates than other patients (4).Use of early, brief interventions may prevent the development of more severe cases of alcohol problems (5), and may reduce the risk of future health problems or injury (6-8). The importance of treating alcohol problems among ED and trauma center patients is reflected in national recommendations (9), and a recent mandate that requires all trauma centers to provide screening and brief intervention services for alcohol problems (10). Motivational Interviewing (MI) (11) reduces drinking and/or associated problems with patients in EDs or trauma ce...
