This study examined the extent to which protective behavioral strategies (PBS) mediated the influence of drinking motives on alcohol consumption, and if these hypothesized relationships were corroborated across subsamples of gender and race.
Online surveys were completed by 1592 heavy drinking college undergraduates from two universities (49.9% male and 50.1% female; 76.9% Caucasian and 23.1% Asian). Independent samples t-tests compared males and females as well as Caucasians and Asians on measures of drinking motives, PBS use, and alcohol consumption, and structural equation models examined the mediating role of PBS.
Consistent with predictions, t-tests revealed that males reported greater levels of consumption than females, but females reported greater use of PBS than males. Caucasians reported greater consumption levels, endorsed higher enhancement motives, and higher PBS related to serious harm reduction, but Asians endorsed higher coping and conformity motives, and PBS focused on stopping/limiting drinking. In multiple-sample SEM analyses, PBS were shown to largely mediate the relationship between motives and consumption in all demographic subsamples.
Findings indicate that PBS use leads to reductions in drinking despite pre-established drinking motives, hence pointing to the potential value of standalone PBS skills training interventions in lowering alcohol use among diverse groups of heavy drinking college students.
本研究考察了保护性行为策略(PBS)在多大程度上调节了饮酒动机对饮酒的影响,以及这些假设的关系是否在性别和种族的亚组中得到证实。
两所大学的 1592 名重度饮酒大学生完成了在线调查(49.9%为男性,50.1%为女性;76.9%为白种人,23.1%为亚洲人)。独立样本 t 检验比较了男性和女性以及白种人和亚洲人在饮酒动机、PBS 使用和饮酒量方面的差异,结构方程模型检验了 PBS 的中介作用。
与预测一致,t 检验显示男性的饮酒量高于女性,但女性的 PBS 使用量高于男性。白种人报告的饮酒量更高,增强动机更高,与严重伤害减少相关的 PBS 更高,但亚洲人报告的应对和从众动机更高,以及专注于停止/限制饮酒的 PBS。在多样本 SEM 分析中,PBS 在所有人口统计学亚组中都显示出在动机和饮酒之间的关系中起主要中介作用。
研究结果表明,尽管存在既定的饮酒动机,但 PBS 的使用会导致饮酒量减少,这表明独立的 PBS 技能培训干预措施在降低不同群体重度饮酒大学生的饮酒量方面具有潜在价值。
