Brief Internet interventions have been shown to reduce alcohol consumption. This trial intended to compare the effects of one such brief intervention to an extended Internet intervention for problem drinkers.
Using online advertising, 490 participants, 18 years or older, were recruited and randomized to receive a brief ( CheckYourDrinking.net ) versus an extended ( AlcoholHelpCentre.net ) Internet intervention and were followed up at 6, 12, and 24 months. The per protocol primary analysis assessed difference between condition at the 12-month follow-up.
The follow-up rate at 12 months was 83.3 %. ANCOVAs of the primary (Alcohol Use Disorder Identification Test (AUDIT)-C) and secondary outcome variables (drinks in a typical week, highest number of drinks on one occasion-baseline drinking as covariate) revealed no significant (p > 0.05) differences between the interventions. Similarly, combined analyses of the 6-, 12-, and 24-month follow-up revealed no significant differences between interventions at all time points.
The present study does not provide support for the added benefit of an extended Internet intervention for problem drinkers over a brief Internet intervention.
简短的网络干预已被证明可减少酒精摄入量。本试验旨在比较一种此类简短干预与针对问题饮酒者的扩展网络干预的效果。
通过在线广告招募了490名18岁及以上的参与者，并将其随机分组，分别接受简短的（CheckYourDrinking.net）和扩展的（AlcoholHelpCentre.net）网络干预，并在6个月、12个月和24个月时进行随访。按方案进行的主要分析评估了12个月随访时不同干预组之间的差异。
12个月时的随访率为83.3%。对主要结局变量（酒精使用障碍识别测试（AUDIT-C））和次要结局变量（典型一周内的饮酒量、单次饮酒的最高量 - 以基线饮酒量作为协变量）进行的协方差分析显示，干预组之间无显著差异（p>0.05）。同样，对6个月、12个月和24个月随访的综合分析表明，在所有时间点，干预组之间均无显著差异。
本研究不支持针对问题饮酒者的扩展网络干预比简短网络干预具有更多益处这一观点。
