Abstract
Objective: Subjective intoxication (SI) when drinking may serve as an internal barometer of whether to continue drinking or engage in potentially unsafe behavior. Mobile assessments offer the potential to use SI as a prospective risk indicator during drinking episodes; little evidence exists for the validity of real-time SI measures. We test the correspondence of SI with estimated blood alcohol concentration and transdermal alcohol concentration (TAC) in young adults' natural settings. We provide a novel test of whether SI features (peak and mean SI) uniquely predict consequences adjusting for alcohol concentration.
Method: Two hundred twenty-two heavy-drinking young adults (Mage = 22.3, 64% female, 79% non-Hispanic White, 84% undergraduates) participated in a 6-day study that used ecological momentary assessment of drinking and TAC sensors. SI was assessed every 30 min during drinking episodes. Multilevel modeling was used to test hypotheses.
Results: Momentary SI and estimated blood alcohol concentration had moderate associations at the moment and day levels (standardized βs = 0.5-0.6); SI was moderately associated with TAC at the day level (βs = 0.5). Associations between SI and alcohol concentration varied widely between persons and across days. Day-level SI features predicted consequences when adjusting for alcohol concentration (incidence rate ratios, IRRs = 1.29-1.70).
Conclusions: Our two-item SI measure shows evidence of validity in real-world settings with heavy-drinking young adults. SI was significantly correlated with alcohol concentration and was a unique predictor of consequences. The strength of these associations varied greatly across persons and days. Real-time SI measurement may be useful in preventive interventions, but continued research is needed into when and for whom momentary SI is most predictive of risk.

目的：饮酒时的主观醉意（SI）可作为是否继续饮酒或从事潜在不安全行为的内在晴雨表。移动评估为将 SI 用作饮酒过程中的前瞻性风险指标提供了可能；但关于实时 SI 测量的有效性却鲜有证据。我们在年轻人的自然环境中测试了 SI 与估计血液酒精浓度和透皮酒精浓度（TAC）的对应关系。我们对 SI 特征（SI 峰值和平均值）是否能独特预测调整酒精浓度后的后果进行了新颖的测试：222 名酗酒的年轻人（年龄 = 22.3，64% 为女性，79% 为非西班牙裔白人，84% 为本科生）参加了一项为期 6 天的研究，该研究采用了饮酒生态瞬间评估和 TAC 传感器。在饮酒过程中，每隔 30 分钟对 SI 进行一次评估。研究采用多层次模型对假设进行检验：结果：瞬时SI与估计血液酒精浓度在时刻和日水平上有中等程度的相关性（标准化βs = 0.5-0.6）；在日水平上，SI与TAC有中等程度的相关性（βs = 0.5）。SI 与酒精浓度之间的关系因人和因天而异。当调整酒精浓度时，日水平 SI 特征可预测后果（发生率比，IRRs = 1.29-1.70）：结论：我们的两项目SI测量结果表明，在现实世界中对酗酒的年轻人进行测量是有效的。SI与酒精浓度有明显的相关性，是预测后果的独特指标。这些关联的强度在不同的人和不同的天之间存在很大差异。实时 SI 测量可能对预防性干预有用，但还需要继续研究何时以及对哪些人来说瞬间 SI 最能预测风险。(PsycInfo Database Record (c) 2024 APA，保留所有权利）。
