Personalized feedback interventions (PFIs) are associated with small but reliable decreases in alcohol consumption among college students. While they often include information regarding protective behavioral strategies (PBS), PFIs do not typically include feedback aimed to modify normative perceptions of PBS. This study aimed to enhance the efficacy of existing PFIs among college students by incorporating normative feedback on participants' use of PBS.
Students enrolled in undergraduate courses (N = 268) completed baseline and 1-month follow-up assessments of past-month use of PBS, normative perceptions of PBS use, alcohol consumption, and alcohol-related consequences. Participants were randomized to one of three conditions: typical feedback on PBS (typical strategies PFI), descriptive normative feedback on PBS (strategy norms PFI), or assessment-only control (AOC). Participants in the typical strategies PFI and strategy norms PFI conditions received web-based personalized feedback profiles.
Compared to AOC, both the strategy norms PFI and typical strategies PFI were effective in correcting participants' perceptions of other students' engagement in PBS (p = .01) but did not differ significantly from one another. No statistically significant differences were observed between conditions in terms of actual PBS use, alcohol consumption, or alcohol-related consequences at 1-month follow-up (p > .05).
The strategy norms and typical strategies PFIs were both successful in increasing normative perceptions of PBS use, indicating that general (rather than normative) feedback regarding PBS use may be sufficient for changing perceptions of PBS use.
个性化反馈干预(PFIs)与大学生饮酒量的少量但可靠的减少有关。虽然它们通常包括有关保护性行为策略(PBS)的信息,但 PFIs 通常不包括旨在改变 PBS 的规范感知的反馈。本研究旨在通过纳入关于参与者使用 PBS 的规范反馈来增强现有大学生 PFIs 的效果。
参加本科课程的学生(N=268)完成了过去一个月使用 PBS、PBS 使用的规范感知、饮酒量和与饮酒相关的后果的基线和 1 个月随访评估。参与者被随机分配到以下三个条件之一:PBS 的典型反馈(典型策略 PFI)、PBS 使用的描述性规范反馈(策略规范 PFI)或仅评估对照(AOC)。典型策略 PFI 和策略规范 PFI 条件的参与者收到了基于网络的个性化反馈档案。
与 AOC 相比,策略规范 PFI 和典型策略 PFI 都有效地纠正了参与者对其他学生参与 PBS 的感知(p=0.01),但彼此之间没有显著差异。在 1 个月的随访中,在实际 PBS 使用、饮酒量或与饮酒相关的后果方面,条件之间没有观察到统计学上的显著差异(p>.05)。
策略规范和典型策略 PFI 都成功地增加了对 PBS 使用的规范感知,表明关于 PBS 使用的一般(而不是规范)反馈可能足以改变对 PBS 使用的感知。
