Alcohol use above hazardous limits is common among persons with psychiatric disorders, and there is limited knowledge about motives for drinking. The objective of this study was to explore the adequacy of the four-factor structure of drinking motives in an adult psychiatric outpatient population in Sweden by confirming the factor structure in the Drinking Motives Questionnaire (DMQ-R) and in alternative models.
In total, 371 patients responded to the DMQ-R along with the Alcohol Use Disorders Identification Test (AUDIT). AUDIT was used to assess frequency of alcohol consumption, number of drinks consumed on a typical occasion and binge drinking frequency. Confirmatory factor analysis was used to examine the construct validity of the DMQ-R and alternative models, including the short form, DMQ-R SF.
Fit statistics suggested that the original four-factor model had questionable fit (root mean square error of approximation [RMSEA] = 0.10, comparative fit index [CFI] = 0.89, standardised root mean square residual [SRMR] = 0.08). The model with the best fit indices was the DMQ-R SF (RMSEA = 0.07, CFI = 0.97, SRMR = 0.04). When using DMQ-R SF in further analyses enhancement, the most strongly endorsed motives were related to quantity and AUDIT sum score. Coping motives were most strongly related to AUDIT sum score, frequency and binge drinking. Social motives were only related to binge drinking, whereas conformity motives were not statistically associated with any motives.
The study implies that the 12-item short form, DMQ-R SF, could be more appropriate than the original DMQ-R in this group. [Öster C, Arinell H, Nehlin C.

在患有精神疾病的人群中，饮酒量超过危险限度的情况很常见，而关于饮酒动机的了解有限。本研究的目的是通过在饮酒动机问卷（DMQ-R）和替代模型中确认因素结构，探讨瑞典成年精神科门诊患者饮酒动机四因素结构的适宜性。
共有371名患者对DMQ-R以及酒精使用障碍识别测试（AUDIT）进行了回应。AUDIT用于评估饮酒频率、典型场合饮酒量以及暴饮频率。验证性因素分析用于检验DMQ-R和替代模型（包括简版DMQ-R SF）的结构效度。
拟合统计表明，原始的四因素模型拟合度存疑（近似均方根误差[RMSEA]=0.10，比较拟合指数[CFI]=0.89，标准化均方根残差[SRMR]=0.08）。拟合指数最佳的模型是DMQ-R SF（RMSEA=0.07，CFI=0.97，SRMR=0.04）。在进一步分析增强中使用DMQ-R SF时，最常被认可的动机与饮酒量和AUDIT总分相关。应对动机与AUDIT总分、频率和暴饮最为相关。社交动机仅与暴饮相关，而从众动机与任何动机均无统计学关联。
该研究表明，在这一群体中，12项简版DMQ-R SF可能比原始的DMQ-R更合适。[Öster C, Arinell H, Nehlin C. 瑞典精神科患者的饮酒动机问卷：四因素结构的探索。药物与酒精评论2017；36：400-407]
