OBJECTIVE Test whether frequent protective behavioral strategies (PBS) users report (a) fewer alcohol-related consequences and (b) less risky alcohol intoxication dynamics (measured via transdermal alcohol concentration [TAC] sensor "features") in daily life. METHOD Two hundred twenty-two frequently heavy-drinking young adults (Mage = 22.3 years) wore TAC sensors for 6 consecutive days. TAC features peak (maximum TAC), rise rate (speed of TAC increase), and area under the curve (AUC) were derived for each day. Negative alcohol-related consequences were measured in the morning after each self-reported drinking day. Past-year PBS use was measured at baseline. RESULTS Young adults reporting more frequent baseline PBS use showed (a) fewer alcohol-related consequences and (b) lower intoxication dynamics on average (less AUC, lower peaks, and slower rise rates). Limiting/stopping and manner of drinking PBS showed the same pattern of findings as the total score. Serious harm reduction PBS predicted fewer negative alcohol-related consequences, but not TAC features. Multilevel path models showed that TAC features peak and rise rate partially explained associations between PBS (total, limiting/stopping, and manner of drinking) and consequences. Independent contributions of PBS subscales were small and nonsignificant, suggesting that total PBS use was a more important predictor of risk/protection than the specific types of PBS used. CONCLUSIONS Young adults using more total PBS may experience fewer alcohol-related consequences during real-world drinking episodes in part through less risky intoxication dynamics (TAC features). Future research measuring PBS at the daily level is needed to formally test TAC features as day-level mechanisms of protection from acute alcohol-related consequences.

基线保护性行为策略的使用预测了更温和的经皮酒精浓度动态以及在年轻人自然环境中饮酒的更少负面后果。

目的 测试频繁的保护行为策略 (PBS) 用户在日常生活中是否报告 (a) 较少的酒精相关后果和 (b) 风险较低的酒精中毒动态（通过透皮酒精浓度 [TAC] 传感器“功能”测量）。方法 222 名经常酗酒的年轻人（Mage = 22.3 岁）连续 6 天佩戴 TAC 传感器。每天导出 TAC 特征峰值（最大 TAC）、上升率（TAC 增加速度）和曲线下面积 (AUC)。在每个自我报告的饮酒日后的早晨测量与酒精相关的负面后果。去年 PBS 的使用情况是在基线时进行测量的。结果 报告基线 PBS 使用频率较高的年轻人显示 (a) 酒精相关后果较少，(b) 平均中毒动态较低（AUC 较低、峰值较低、上升速度较慢）。限制/停止和饮用 PBS 的方式显示出与总分相同的结果模式。严重减少伤害 PBS 预测与酒精相关的负面后果会减少，但 TAC 特征却没有预测。多级路径模型表明，TAC 的峰值和上升率部分解释了 PBS（总量、限制/停止和饮酒方式）与后果之间的关联。PBS 子量表的独立贡献很小且不显着，这表明 PBS 的总使用量是比使用的特定类型 PBS 更重要的风险/保护预测因子。结论 使用更多 PBS 的年轻人在现实世界的饮酒事件中可能会经历更少的与酒精相关的后果，部分原因是风险较小的中毒动态（TAC 特征）。未来的研究需要在日常水平上测量 PBS，以正式测试 TAC 功能作为防止急性酒精相关后果的日常机制。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
