基于网络的简短酒精干预措施有可能以低成本接触到大量个人;然而，迄今为止几乎没有进行过受控评估。本研究旨在评估性别特异性与性别非特异性个性化规范性反馈（PNF）的有效性，单次与半年一次的管理，在一项为期2年的随机对照试验，针对大量饮酒的大学生样本。参与者包括818名新生（57.6%为女性; 42%为非白人），他们在基线前一个月报告了1次或多次重度饮酒事件。参与者被随机分配到2（性别特异性PNF vs.性别非特异性PNF）× 2（PNF单次vs.一年两次给药）+ 1（注意力控制）设计中。每6个月进行一次评估，为期2年。分层广义线性模型的结果提供了适度的影响，每周饮酒和酒精相关的问题，但不重情节饮酒。相对于对照组，性别特异性一年两次的PNF与每周饮酒量随时间的减少相关（d =-0.16，95%CI [-0.02，-0.31]），这种影响部分由感知规范的变化介导。对于女性，而不是男性，与对照组相比，性别特异性半年一次的PNF与酒精相关问题随时间的减少有关（d =-0.29，95%CI [-0.15，-0.58]）。几乎没有其他明显的影响。目前的研究提供了适度的支持，使用半年一次管理的基于网络的性别特异性PNF作为替代更昂贵的指示性预防策略。
Web-based brief alcohol interventions have the potential to reach a large number of individuals at low cost; however, few controlled evaluations have been conducted to date. The present study was designed to evaluate the efficacy of gender-specific versus gender-nonspecific personalized normative feedback (PNF) with single versus biannual administration in a 2-year randomized controlled trial targeting a large sample of heavy-drinking college students. Participants included 818 freshmen (57.6% women; 42% non-Caucasian) who reported 1 or more heavy-drinking episodes in the previous month at baseline. Participants were randomly assigned in a 2 (gender-specific vs. gender-nonspecific PNF) × 2 (single vs. biannual administration of PNF) + 1 (attention control) design. Assessments occurred every 6 months for a 2-year period. Results from hierarchical generalized linear models provided modest effects on weekly drinking and alcohol-related problems but not on heavy episodic drinking. Relative to control, gender-specific biannual PNF was associated with reductions over time in weekly drinking (d = −0.16, 95% CI [−0.02, −0.31]), and this effect was partially mediated by changes in perceived norms. For women, but not men, gender-specific biannual PNF was associated with reductions over time in alcohol-related problems relative to control (d =−0.29, 95% CI [−0.15,−0.58]). Few other effects were evident. The present research provides modest support for the use of biannually administered web-based gender-specific PNF as an alternative to more costly indicated prevention strategies.
