Heavy alcohol use in college is associated with a risk of developing alcohol use disorder. Characterizing variability in individual risk factors for alcohol use could help mitigate risk by informing personalized approaches to prevention. This study examined the validity of a brief measure for identifying reward/relief drinking phenotypes in non-treatment-seeking young adults.
College students (n = 454) who reported binge drinking completed the Drinking Motives Questionnaire-Revised-Short Form (DMQ-R-SF). Confirmatory factor and latent profile analyses (CFA; LPA) of the DMQ-R-SF were performed to assess structural validity and identify reward/relief drinking subgroups. We compared models measuring reward drinking with the DMQ-R-SF enhancement motives (reward-enhancement) subscale to models measuring reward drinking with enhancement and social motives (reward-enhancement/social). Across models, relief drinking was measured with coping motives. We examined associations between reward/relief drinking subgroups and alcohol and personality variables concurrently and prospectively at a 6-week follow-up.
A two-factor reward and relief structure of the DMQ-R-SF was supported. Three latent profiles were identified (low reward/low relief: n = 133, high reward/low relief: n = 249; high reward/high relief: n = 72). Both CFA and LPA models that utilized reward-enhancement/social items indicated a better fit than reward-enhancement items alone. At baseline, individuals in the high-reward/high-relief profile demonstrated the poorest alcohol use outcomes and higher negative affect. Those in the high-reward/low-relief profile demonstrated greater alcohol use severity than those in the low-reward/low-relief profile. Prospectively, individuals classified in the high-reward/low-relief subgroup reported greater binge drinking frequency and those in the high-reward/high-relief profile reported greater alcohol consequences.
The DMQ-R-SF is a valid measure for identifying reward and relief drinking subgroups in college students with binge drinking and could have utility for precision prevention efforts that target individuals in the high-reward/low-relief and high-reward/high-relief subgroups.
在大学中大量饮酒与酒精使用障碍的发生风险相关。明确酒精使用个体风险因素的变异性，有助于通过提供个性化预防方法来降低风险。本研究检验了一种简短测量方法在识别未寻求治疗的年轻成年人中奖励/缓解性饮酒表型方面的有效性。
报告有暴饮行为的大学生（n = 454）完成了《饮酒动机问卷修订简版》（DMQ-R-SF）。对DMQ-R-SF进行验证性因子分析和潜在类别分析（CFA；LPA），以评估结构效度并识别奖励/缓解性饮酒亚组。我们将用DMQ-R-SF增强动机（奖励增强）分量表测量奖励性饮酒的模型，与用增强和社交动机（奖励增强/社交）测量奖励性饮酒的模型进行比较。在所有模型中，用应对动机来测量缓解性饮酒。我们在6周随访时同时及前瞻性地研究了奖励/缓解性饮酒亚组与酒精及人格变量之间的关联。
支持了DMQ-R-SF的双因素奖励和缓解结构。识别出三个潜在类别（低奖励/低缓解：n = 133；高奖励/低缓解：n = 249；高奖励/高缓解：n = 72）。使用奖励增强/社交项目的CFA和LPA模型均显示比仅使用奖励增强项目的模型拟合度更好。在基线时，高奖励/高缓解类别中的个体酒精使用结果最差且负性情绪更高。高奖励/低缓解类别中的个体酒精使用严重程度高于低奖励/低缓解类别中的个体。前瞻性来看，分类为高奖励/低缓解亚组的个体报告的暴饮频率更高，而高奖励/高缓解类别中的个体报告的酒精相关后果更多。
DMQ-R-SF是一种识别有暴饮行为的大学生中奖励和缓解性饮酒亚组的有效测量方法，对于针对高奖励/低缓解和高奖励/高缓解亚组个体的精准预防工作可能有用。
