OBJECTIVE
Extant survey measures of subjective response to alcohol, an important risk factor for alcohol problems, query the number of drinks to experience alcohol effects but do not consider how individuals experience them. We tested whether new measures of the intensity of alcohol effects, alongside the "number of drinks," contributed uniquely or interactively in predicting alcohol problems. We examined associations among these subjective response variables with racial identity and sex assigned at birth.
METHOD
Participants ( = 246; 18-50 years; 44.3% Black; 55.7% White; 58.4% assigned female; 41.6% assigned male) were oversampled for alcohol-related risk and completed an online survey. Participants reported the number of drinks to experience alcohol effects (Fleming et al., 2016), the intensity of these alcohol effects, alcohol-related problems, and covariates (heavy drinking frequency, tolerance, demographics).
RESULTS
According to confirmatory factor analyses, two factors underlay the number of drinks items ("stimulation number of drinks," "sedation number of drinks") and the same for alcohol effect intensity items ("stimulation intensity," "sedation intensity"). Stimulation intensity and sedation number of drinks were significantly associated with, and interacted to predict, alcohol problems; individuals reporting both greater stimulation intensity and needing more drinks to experience sedation showed the greatest risk. Black relative to White individuals reported greater intensity of, and needing more drinks to feel, stimulation. Male relative to female individuals reported needing more drinks to feel sedation.
CONCLUSIONS
Participants' self-reports of the intensity of alcohol effects may capture an important aspect of subjective response that could improve existing survey-based measures of this important alcohol-related risk factor. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
目的
对酒精主观反应的现有调查测量方法是酒精问题的一个重要风险因素，它询问达到酒精效应的饮酒量，但未考虑个体对这些效应的体验方式。我们测试了酒精效应强度的新测量方法与“饮酒量”一起，在预测酒精问题时是单独起作用还是相互作用。我们研究了这些主观反应变量与种族身份和出生时指定性别的关联。
方法
参与者（n = 246；18 - 50岁；44.3%为黑人；55.7%为白人；58.4%被指定为女性；41.6%被指定为男性）因与酒精相关的风险被过度抽样，并完成了一项在线调查。参与者报告达到酒精效应的饮酒量（Fleming等人，2016年）、这些酒精效应的强度、与酒精相关的问题以及协变量（重度饮酒频率、耐受性、人口统计学特征）。
结果
根据验证性因素分析，饮酒量项目（“刺激饮酒量”、“镇静饮酒量”）有两个因素，酒精效应强度项目（“刺激强度”、“镇静强度”）也是如此。刺激强度和镇静饮酒量与酒精问题显著相关，并相互作用以预测酒精问题；报告刺激强度更高且需要更多饮酒量才能达到镇静的个体风险最大。与白人个体相比，黑人个体报告的刺激强度更高，且需要更多饮酒量才能感受到刺激。与女性个体相比，男性个体报告需要更多饮酒量才能感受到镇静。
结论
参与者对酒精效应强度的自我报告可能捕捉到主观反应的一个重要方面，这可能会改进现有的基于调查的这一重要酒精相关风险因素的测量方法。（PsycInfo数据库记录（c）2025美国心理学会，保留所有权利）
