毒品预防运动通常寻求改变与药物使用相关的预期结果，但很少考虑违反这种预期的影响。本研究通过调查大麻期望的变化是否与随后的未来大麻意图相关，详细介绍了预期违反框架在真实的世界背景下的应用。通过二次分析对来自全国父母和青少年调查的青少年队列（N = 1，344;年龄范围= 12-18岁）进行分析。基线时的非使用者在1年后进行评估。预期的变化与意图的变化显著相关（p <0.001）。此外，在大多数情况下，预期和意图的变化与成为用户的人之间的关系最密切。最终模型解释了31%的方差（p <0.001）。与实验室研究一致，大麻期望的变化预测了大麻意图的变化。这些结果建议在描述大麻开始的负面结果时要谨慎。如果青少年得出结论，使用大麻的危害并不像他们所预期的那样严重，那么使用大麻的意图可能会加剧。
Drug prevention campaigns commonly seek to change outcome expectancies associated with substance use, but the effects of violating such expectancies are rarely considered. This study details an application of the expectancy violation framework in a real world context by investigating whether changes in marijuana expectations are associated with subsequent future marijuana intentions. A cohort of adolescents (N = 1,344; age range = 12-18 years) from the National Survey of Parents and Youth was analyzed via secondary analysis. Nonusers at baseline were assessed 1 year later. Changes in expectancies were significantly associated with changes in intentions (p < .001). Moreover, in most cases, changes in expectancies and intentions had the strongest relationship among those who became users. The final model accounted for 31% of the variance (p < .001). Consistent with laboratory studies, changes in marijuana expectancies were predictive of changes in marijuana intentions. These results counsel caution when describing negative outcomes of marijuana initiation. If adolescents conclude that the harms of marijuana use are not as grave as they had been led to expect, intentions to use might intensify.
