The purpose of this study was to evaluate the efficacy of personalized normative feedback (PNF) on college student alcohol-related risky sexual behavior (RSB).
In a randomized controlled trial, 480 (57.6% female) sexually active college students were stratified by gender and level of drinking and randomly assigned to an alcohol-only intervention, an alcohol-related RSB-only intervention, a combined alcohol and alcohol-related RSB intervention, or control. All assessment and intervention procedures were Web-based.
Results indicated a significant reduction in drinking outcomes for the alcohol only and the combined alcohol and alcohol-related RSB interventions relative to control. Findings further demonstrated a significant reduction in alcohol-related RSB outcomes for the alcohol-related RSB only and the combined alcohol and alcohol-related RSB interventions relative to control. There were no significant intervention effects on alcohol-related negative consequences. These findings demonstrate that the combined alcohol and alcohol-related RSB intervention was the only intervention successful at reducing both drinking and alcohol-related RSB outcomes relative to control. There were no significant differences when comparing the combined alcohol and alcohol-related RSB intervention to the alcohol-only intervention or the alcohol-related RSB-only intervention. Finally, results suggested that the intervention effects on high-risk behaviors were mediated by reductions in descriptive normative perceptions.
These findings demonstrate that PNF specific to drinking in sexual situations was needed to reduce alcohol-related RSB. Furthermore, this study highlights the potential utility of a brief intervention that can be delivered via the Internet to reduce high-risk drinking and alcohol-related RSB among college students.
本研究旨在评估个性化规范反馈(PNF)对大学生酒精相关危险性行为(RSB)的疗效。
在一项随机对照试验中,480名(57.6%为女性)有性行为的大学生按性别和饮酒水平分层,并随机分配至仅酒精干预组、仅酒精相关危险性行为干预组、酒精与酒精相关危险性行为联合干预组或对照组。所有评估和干预程序均通过网络进行。
结果表明,仅酒精干预组以及酒精与酒精相关危险性行为联合干预组相对于对照组,饮酒结果有显著降低。研究结果进一步表明,仅酒精相关危险性行为干预组以及酒精与酒精相关危险性行为联合干预组相对于对照组,酒精相关危险性行为结果有显著降低。对酒精相关负面后果没有显著的干预效果。这些发现表明,相对于对照组,酒精与酒精相关危险性行为联合干预是唯一成功降低饮酒和酒精相关危险性行为结果的干预措施。将酒精与酒精相关危险性行为联合干预组与仅酒精干预组或仅酒精相关危险性行为干预组进行比较时,没有显著差异。最后,结果表明对高风险行为的干预效果是通过描述性规范认知的降低来介导的。
这些发现表明,需要针对性行为情境中的饮酒进行个性化规范反馈,以减少酒精相关危险性行为。此外,本研究强调了一种可通过互联网提供的简短干预措施在减少大学生高风险饮酒和酒精相关危险性行为方面的潜在效用。
