大学生经历了各种各样的影响，酒精使用和评估他们的经验上的连续从消极到积极的。使用通过手机收集的日常报告，我们研究了饮酒后果的心理测量特性和这些后果的评价。参与者为349名本科生（平均年龄19.7 [SD = 1.26]，53.4%为女性）。数据进行了分析，采用多层次因素分析框架，将二进制项目（后果）和正态分布的项目（评价）。我们的模型收敛于2个因素-积极和消极-与类似的负载之间和内部的人。组内相关系数为积极的后果和他们的评价范围从0.30至0.40，而值为消极的后果是更多的变量。组内相关系数的负面评价较高，这表明评价更像是特质相比，经验的后果，这可能是依赖于上下文。总体上的概化系数是好到优秀的，这表明在个人平均值和每日平均值水平高度可靠的尺度。然而，可能是由于二进制规模和不频繁，在日常水平的负面后果的概化系数有点低。收敛有效性证明了（a）基线罗格斯酒精问题指数和酒精使用障碍识别测试得分与日常积极和消极后果的潜在因素之间的正相关性，和（B）日常饮酒和日常后果之间的正相关性和后果的评价。总体而言，这项措施表现出良好的心理测量特性，用于研究日常和滞后的关系，酒精使用和相关的后果。
College students experience a variety of effects resulting from alcohol use and evaluate their experiences on a continuum from negative to positive. Using daily reports collected via cell phone, we examined the psychometric properties of alcohol use consequences and evaluations of those consequences. Participants were 349 undergraduate students (mean age 19.7 [SD = 1.26], 53.4% female). Data were analyzed using a multilevel factor analysis framework, incorporating binary items (consequences) and normally distributed items (evaluations). Our model converged on 2 factors-positive and negative-with similar loadings between-and within-persons. Intraclass correlation coefficients for positive consequences and their evaluations ranged from .30 to.40, whereas values for negative consequences were more variable. Intraclass correlation coefficients for negative evaluations were higher, suggesting evaluations were more trait-like compared to experience of consequences which may be context dependent. Generalizability coefficients on the whole were good to excellent, suggesting highly reliable scales at both person-mean and daily-mean levels. However, likely due to binary scale and infrequency, the generalizability coefficients for negative consequences at the daily level was somewhat low. Convergent validity was demonstrated by (a) positive associations between baseline Rutgers Alcohol Problem Index and Alcohol Use Disorders Identification Test scores with latent factors for daily positive and negative consequences, and (b) positive associations between daily drinking and daily consequences and evaluations of consequences. Overall, this measure demonstrated good psychometric properties for use in studies examining daily and lagged relationships between alcohol use and related consequences.
