Previous research has reported that sleep problems longitudinally predict both onset of cannabis use and cannabis-related problems. However, the mediators of this relationship remain unclear. The present study examined (a) the concurrent relationship between insomnia symptoms and hazardous cannabis use and (b) examined whether use of protective behavioral strategies (PBS) for cannabis mediated this relationship among college student cannabis users. Participants were 984 (69.9% female) college students who reported consuming cannabis at least once in the past month and completed measures of insomnia, cannabis PBS, and cannabis misuse. Data were analyzed by structural equation modeling for binary and count outcomes. The significance of the mediator was evaluated using bias-corrected bootstrap confidence intervals. Insomnia symptoms were associated with an increase in the odds of hazardous cannabis use and possible cannabis use disorder. Cannabis PBS significantly mediated the relationship between insomnia symptoms and hazardous cannabis use, cannabis use disorder symptoms, and cannabis-related problems. Specifically, higher reports of insomnia symptoms were associated with lower use of cannabis PBS; which in turn was associated with an increase in the odds of hazardous cannabis use and possible cannabis use disorder, as well as a higher report of cannabis-related problems. Implications of these findings on the prevention of cannabis use problems among college students in the United States were discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
先前的研究报告称，睡眠问题会在纵向预测大麻使用和大麻相关问题的出现。然而，这种关系的中介因素仍不清楚。本研究考察了（a）失眠症状与危险大麻使用之间的并发关系，以及（b）考察了在大学生大麻使用者中，大麻保护性行为策略（PBS）的使用是否会调节这种关系。参与者是 984 名（69.9%为女性）报告过去一个月至少吸食过一次大麻的大学生，他们完成了失眠、大麻 PBS 和大麻滥用的测量。通过结构方程模型对二项式和计数结果进行分析。使用偏置校正的自举置信区间评估中介的显著性。失眠症状与危险大麻使用和可能的大麻使用障碍的几率增加有关。大麻 PBS 显著调节了失眠症状与危险大麻使用、大麻使用障碍症状和大麻相关问题之间的关系。具体来说，更高的失眠症状报告与更低的大麻 PBS 使用相关；而这又与危险大麻使用和可能的大麻使用障碍几率增加以及大麻相关问题的更高报告有关。讨论了这些发现对预防美国大学生大麻使用问题的意义。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
