Drinking motives are vital in identifying risk factors and better understanding alcohol-related outcomes. However, context-specific motivations could provide greater motivational perspective on high-risk context-specific alcohol use behaviors such as prepartying (consuming alcohol prior to attending one's intended destination) than general alcohol motivations. In the current study, students' open-ended responses to reasons for prepartying were collected from a large diverse sample (n=2497), and the most commonly offered reasons were used to create a prepartying motivations inventory (PMI) that was then administered to a different sample (n=1085). A split-half validation procedure was used for the purpose of evaluating the PMI's factor structure. Exploratory and confirmatory factor analyses yielded a final 16-item measure consisting of four distinct, but inter-related, factors: Interpersonal Enhancement, Situational Control, Intimate Pursuit, and Barriers to Consumption. Internal consistency reliability, discriminant validity, and criterion-related validity were empirically demonstrated. Results support the notion that individuals preparty for a variety of reasons that are distinct from general motives. Researchers are encouraged to use the PMI in future research with young adults to provide further understanding of prepartying behavior and its psychosocial correlates.
饮酒动机对于识别风险因素和更好地理解与酒精相关的结果至关重要。然而，特定情境下的动机可能比一般的饮酒动机更能从动机角度理解高风险特定情境下的饮酒行为，如预饮（在前往预期目的地之前饮酒）。在本研究中，从一个大型多样化的样本（n=2497）中收集了学生对预饮原因的开放式回答，并使用最常提到的原因创建了预饮动机量表（PMI），然后对另一个样本（n=1085）进行了测试。采用半分割验证程序来评估 PMI 的因素结构。探索性和验证性因素分析得出了最终的 16 项量表，包括四个不同但相互关联的因素：人际增强、情境控制、亲密追求和消费障碍。内部一致性信度、判别效度和效标关联效度在实证研究中得到了验证。结果支持这样一种观点，即个体有多种不同于一般动机的预饮原因。鼓励研究人员在未来对年轻人的研究中使用 PMI，以进一步了解预饮行为及其心理社会相关性。
