To examine the Acquired Preparedness Model using a behavioral impulsivity facet and positive marijuana expectancies to examine direct and indirect effects on marijuana use and related problems. : 250 college students (61.7% female, 54% white) recruited from a southeastern university. : Participants completed an online survey of delay reward discounting, marijuana expectancies, consideration of future consequences, and marijuana-related outcomes. : Delay reward discounting and consideration of future consequences related to marijuana-related problems, but not marijuana use. However, positive marijuana expectancies did not mediate the relation between impulsivity and marijuana outcomes. : These results emphasize delay reward discounting and consideration of future consequences as important factors associated with marijuana-related problems. Interventions aimed at decreasing delay reward discounting and augmenting future orientation may be effective in college students who report light to moderate marijuana use. Future studies would benefit from longitudinal study designs using multiple impulsivity measures among light and heavy users.
采用行为冲动性特征和积极的大麻预期来检验获得性准备模型，以检验对大麻使用和相关问题的直接和间接影响。研究对象为来自东南大学的 250 名大学生（61.7%为女性，54%为白人）。参与者完成了一项关于延迟奖励折扣、大麻预期、未来后果考虑和大麻相关结果的在线调查。延迟奖励折扣和对未来后果的考虑与大麻相关问题有关，但与大麻使用无关。然而，积极的大麻预期并不能调节冲动与大麻结果之间的关系。这些结果强调了延迟奖励折扣和对未来方向的考虑是与大麻相关问题相关的重要因素。针对报告轻度至中度大麻使用者的延迟奖励折扣和增强未来取向的干预措施可能是有效的。未来的研究将受益于使用轻度和重度使用者的多种冲动性测量进行的纵向研究设计。
