Alcohol protective behavioral strategies (PBS) have been proposed as mechanisms of change underlying interventions for reducing alcohol use and alcohol-related problems. Few studies have examined PBS use among non-college student populations and no study has examined PBS use among adult injured patients. The current study tested types of PBS as mediators of the effects of a brief motivational intervention (BMI) delivered in the trauma care setting on alcohol-related problems.
Secondary data analyses were conducted using data from a multisite randomized controlled trial of brief intervention in the trauma care setting. The current study used data from a subset of participants who reported having consumed alcohol at least once at 3-month follow-up (N = 324). Following a baseline assessment, participants were assigned to either brief advice (BA; n = 107), BMI (n = 119), or BMI with a telephone booster (BMI + B; n = 98). Participants completed measures of PBS at 3-month follow-up and of alcohol-related problems at baseline and 6-month follow-up. A multiple mediation model was conducted to simultaneously test the mediation effects of types of PBS.
BMI and BMI + B relative to BA did not increase PBS use. However, more frequent use of certain types of PBS at 3-month follow-up were predictors of greater reductions in alcohol-related problems from baseline to 6-month follow-up. There were no statistically significant mediation effects.
The present study suggests that PBS use reduces alcohol-related problems among trauma patients and implications for future studies are discussed.
酒精保护性行为策略 (PBS) 被提出作为减少饮酒和与酒精相关问题的干预措施的变化机制。很少有研究调查非大学生群体中的 PBS 使用情况，也没有研究调查成年受伤患者中的 PBS 使用情况。本研究测试了在创伤护理环境中提供的简短动机干预 (BMI) 对酒精相关问题的影响的 PBS 类型作为中介的作用。
使用多地点随机对照试验中简短干预的创伤护理环境中的数据进行二次数据分析。本研究使用了在 3 个月随访时至少有一次饮酒报告的参与者的子集数据（N=324）。在基线评估后，参与者被分配到简短建议 (BA；n=107)、BMI (n=119) 或 BMI 加电话增强剂 (BMI+B；n=98)。参与者在 3 个月随访时完成了 PBS 测量，并在基线和 6 个月随访时完成了酒精相关问题的测量。进行了多重中介模型分析，以同时测试 PBS 类型的中介作用。
与 BA 相比，BMI 和 BMI+B 并没有增加 PBS 的使用。然而，在 3 个月随访时更频繁地使用某些类型的 PBS 是从基线到 6 个月随访时酒精相关问题减少的预测因素。没有统计学上显著的中介作用。
本研究表明，PBS 的使用减少了创伤患者的酒精相关问题，并讨论了对未来研究的影响。
