获得性准备模型（APM）将人格特质和心理社会学习整合到个体启动和持续饮酒的机制中。本研究探讨了冲动性，酒精预期，酒精使用和酒精问题之间的人内关联，以告知饮酒的日常过程模型和测试APM。参与者是89名大学生饮酒者，他们完成了14天的瞬时报告（三个随机报告和两个用户发起的报告）。多层次的中介分析研究冲动和酒精使用和问题之间的日常关联是否是由积极和消极的预期介导的。饮酒前，日常冲动与日常积极期望呈正相关。更大的每日积极期望与当天更多的酒精消耗和酒精问题有关。间接影响是显着的，表明比平时更大的冲动与更大的酒精使用和酒精问题，通过更大的积极预期。冲动与负预期在主题内和主题之间的水平呈正相关，但负预期并没有作为冲动和酒精的结果之间的中介。这是第一次在日间水平上测试APM的研究。研究结果支持日常波动的信念，酒精的积极影响作为一个显着的机制，解释日常冲动和酒精使用水平之间的联系。由于冲动性与当天接近饮酒的预期状态的变化有关，因此这些信息可用于制定预防和干预计划，以减少酒精危害。
The acquired preparedness model (APM) integrates personality traits and psychosocial learning to posit amechanism whereby individuals initiate and continue alcohol use. The present study examined within-person associations between impulsivity, alcohol expectancies, alcohol use, and alcohol problems to inform daily process models of drinking and test the APM. Participants were 89 college student drinkers who completed momentary reports (three random and two user-initiated reports) for 14 days. Multilevel mediation analyses examined whether daily associations between impulsivity and alcohol use and problems were mediated by positive and negative expectancies. Daily impulsivity was positively associated with daily positive expectancies, prior to drinking. Greater daily positive expectancies were associated with more alcohol consumed and alcohol problems that day. The indirect effects were significant, indicating greater than usual impulsivity was associated with greater alcohol use and alcohol problems through greater positive expectancies. Impulsivity was positively associated with negative expectancies at the within-subject and between-subject levels, but negative expectancies did not serve as a mediator between impulsivity and either alcohol outcome. This is the first study to test the APM at the day level. Findings supported daily fluctuations in beliefs regarding the positive effects of alcohol as a salient mechanism explaining the link between daily impulsivity and level of alcohol use. Because impulsivity was linked to changes in expectancy states that were proximal to drinking that day, this information may be used to develop prevention and intervention programs to reduce alcohol harms.
