Home-based alcohol prevention program for parents and children: A randomized controlled trial

Objective To evaluate the effectiveness of a home-based alcohol prevention program to delay initiation of alcohol use in children. Methods In 2011, a total of 1349 sixth-grade children (M = 12.15, SD = 0.47) and their mothers who could read and write Dutch were recruited from primary schools in the northern part of the Netherlands. They participated in a cluster randomized controlled trial with two conditions; (1) intervention group (5 modules which families received by mail every 4 weeks over 5 months), (2) control group (a factsheet information brochure). An independent statistician allocated the schools to the conditions (allocation ratio (1:1)). Participants and data-analyst were blind to randomization. The primary outcome was alcohol initiation. Results Of the participants, 680 were randomized to the intervention and 669 to the control condition. In the intervention condition (N = 540) 5.4% of the children drank alcohol compared to 7.1% in the control condition (N = 601). The difference was not significant (OR = .99, 95% CI = .96-1.02, p = 52). Conclusion The present study showed no effects of 'In control: No alcohol!' on alcohol initiation. A critical evaluation of program design and content, and future studies in different target groups, are suggested. (C) 2016 Elsevier Inc. All rights reserved.
