Computer-based interventions aimed at reducing college student drinking have shown positive effects. The authors compare differences in effects of computer-based personalized normative feedback (PNF) interventions based on delivery modality (in-person vs. remotely) across six previously evaluated studies with similar content.
Three studies included evaluations of a computer-based PNF intervention in which baseline and intervention procedures took place inside a laboratory setting; three separate studies included evaluations of the same intervention in which participants completed the procedures remotely over the Web. Thus, we tested for differences in intervention efficacy by delivery modality. Outcomes included drinks per week, drinking-related consequences, and the putative intervention mechanism, perceived drinking norms.
Evidence from hierarchical linear models indicated that computer-based interventions are less effective at reducing drinking and related consequences when delivered remotely than when delivered in person.
The advantages of interventions delivered remotely are not without cost. Suggestions for why remote computer-based interventions may be less effective are discussed.
旨在减少大学生饮酒行为的计算机辅助干预已显示出积极效果。作者通过六项内容相似的先前评估研究，比较了基于交付方式（面对面与远程）的计算机辅助个性化规范反馈（PNF）干预效果的差异。
三项研究对基于计算机的PNF干预进行了评估，其中基线和干预程序在实验室环境中进行；另外三项独立研究对相同干预进行了评估，参与者通过网络远程完成程序。因此，我们测试了交付方式在干预效果上的差异。结果包括每周饮酒量、与饮酒相关的后果以及假定的干预机制，即感知饮酒规范。
分层线性模型的证据表明，基于计算机的干预在远程交付时比面对面交付时在减少饮酒及相关后果方面效果更差。
远程交付干预的优势并非没有代价。文中讨论了基于计算机的远程干预效果可能较差的原因。
