后天准备模型表明，人格和物质使用之间的联系是由预期介导的。相比之下，人格和物质使用之间的预期调节联系也得到了先前研究的支持。这项研究试图将获得的准备模型扩展到频繁使用大麻的不同样本。从大麻政策列表中招募的5996名参与者对减少紧张的预期、冲动性和每月使用大麻的盎司数进行了评估。紧张减少预期部分介导的冲动和大麻使用之间的关系。此外，预期和冲动相互作用，以预测大麻的使用，与冲动表现出更强的联系时，预期增加使用。这些研究结果支持了物质使用的后天准备模型，以及以前的工作预期调节人格和物质使用之间的联系。冲动的人特别可能使用物质时，他们有积极的期望。消除这些大麻的期望可能有助于防止有问题的使用。
The acquired preparedness model suggests that links between personality and substance use are mediated by expectancies. In contrast, expectancy-moderated links between personality and substance use also have support in previous research. This study sought to extend the acquired preparedness model to a diverse sample of frequent marijuana users. Tension-reduction expectancies, impulsivity, and ounces of marijuana used per month were assessed in 5996 participants recruited from a marijuana policy listserv. Tension-reduction expectancies partially mediated the relation between impulsivity and marijuana use. Additionally, expectancies and impulsivity interacted to predict marijuana use, with impulsivity showing a stronger link to use when expectancies increased. These findings support the acquired preparedness model of substance use as well as previous work on expectancy-moderated links between personality and substance use. Impulsive individuals are particularly likely to use substances when they have positive expectancies about them. Challenging these marijuana expectancies might prove useful in preventing problematic use.
