Comparison of WEB and Interactive Voice Response (IVR) Methods for Delivering Brief Alcohol Interventions to Hazardous-Drinking University Students: A Randomized Controlled Trial.

Andersson, Claes LU (2015) In European Addiction Research 21(5). p.240-252
Abstract
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... (More)
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. © 2015 S. Karger AG, Basel. (Less)
