• This study evaluated automated techniques including personalized normative feedback and protective behavioral strategies, for brief interventions intended to reduce peak alcohol concentrations in university students. After completing baseline assessment, a total of 1,678 hazardous-drinking consumers were randomized to a single or a repeated Internet (WEB) or Interactive Voice Response (IVR) intervention, or to a control group (Single WEB: 323; Single IVR: 329; Repeated WEB: 318; Repeated IVR: 334; Control group: 374). At follow-up, six weeks after baseline, questionnaires were returned by 1,422 participants (Single WEB: 277; Single IVR: 286; Repeated WEB: 259; Repeated IVR: 279; Control group: 321). It was found that peak estimated BAC was reduced in the total group (b –0.14, 95% confidence interval (CI) –0.023; –0.005), in the total (b –0.17, 95% CI –0.027; –0.007) and single (b –0.021, 95% CI –0.032; –0.011) WEB group, and in the total (b –0.011, 95% CI –0.021; –0.015) and repeated (b –0.012, 95% CI –0.023; –0.000) IVR groups, compared to controls. The reduction in peak estimated BAC was greater in the single WEB group compared to the single IVR group (b –0.011, 95% CI –0.022; –0.000). This study concluded that both WEB and IVR interventions have a small but significant effect in reducing heavy episodic drinking, which may be due to the relatively large sample size. Repeated intervention may be needed if delivered by IVR.
