OBJECTIVE The purpose of this randomized controlled study was to examine sex as a moderator of the efficacy of a brief, web-based personalized feedback intervention (eCHECKUP TO GO) on decreasing cognitive risk factors for alcohol use, increasing protective behavioral strategies, and reducing alcohol use among high school seniors. METHOD Participants (n = 311) were high school seniors randomized by class period to the eCHECKUP TO GO intervention or assessment-only control group. Participants completed online surveys at baseline and 30-day follow-up (91.0%; n = 283). RESULTS Students in the intervention group reported a significant reduction in normative perceptions of peer drinking, positive alcohol expectancies, and alcohol use relative to those in the control group. Intervention effects for perceptions of frequency of peer drunkenness and frequency of alcohol use were moderated by sex, with results favoring females. In contrast, we did not find evidence for sex as a moderator of intervention effects for normative perceptions of peer drinking frequency, sex-specific perceptions of peer heavy episodic drinking, positive alcohol expectancies, or peak drinking quantity. Further, we did not find significant intervention or moderator effects for protective behavioral strategies. CONCLUSIONS Results of this study extend the literature by demonstrating the efficacy of the eCHECKUP TO GO for both males and females on reducing cognitive risk factors and alcohol use, although results were significant for a broader range of variables for females. Results also indicate that program content regarding normative feedback and protective behavioral strategies may need modification to be more effective for this age group.

高中生参加eCHECKUP的功效：危险因素，防护行为策略和饮酒的性别差异

目的这项随机对照研究的目的是检查性别，作为基于网络的简短个性化反馈干预措施（eCHECKUP TO GO）的有效性的调节者，该干预措施可降低饮酒的认知危险因素，增加保护性行为策略并减少饮酒在高中生中使用。方法参与者（n = 311）是高中生，按班级划分为eCHECKUP TO GO干预或仅评估对照组。参与者在基线和30天的随访中完成了在线调查（91.0％； n = 283）。结果干预组的学生报告说，与对照组相比，同伴饮酒，积极的酒精期望和饮酒的规范性看法明显减少。性别减轻了对同龄人醉酒频率和饮酒频率的感知的干预作用，其结果偏向女性。相比之下，我们没有发现证据表明性别可以作为对同龄人饮酒频率的规范性看法，同龄人重度发作性饮酒的性别特定看法，酒精期望值或饮酒高峰的干预效果的调节剂。此外，我们没有发现保护行为策略的显着干预或调节作用。结论这项研究的结果通过证明eCHECKUP TO GO对男性和女性的降低认知危险因素和饮酒的功效，扩大了文献范围，尽管对于更大范围的女性变量而言，结果是有意义的。
