失眠在退伍军人中非常普遍，失眠率几乎是平民的两倍。失眠通常与其他心理问题并存，包括药物使用(例如大麻)和感觉到的压力。大部分研究集中在失眠、压力和大麻的使用上，探索大麻作为一种助眠和缓解压力的机制。然而，最近的理论和经验证据表明，失眠、大麻使用和感知的压力之间存在动态相互作用，但很少有纵向研究。通过对1105名9/11事件后退伍军人在12个 月的4个时间点上的评估，我们使用潜在差异得分模型来检验失眠、感知压力和大麻使用之间的比例变化。结果显示，这三种结构之间存在复杂的相互作用。特别是，我们发现，先前的失眠水平越高，感知到的压力就越大，先前的压力水平越大，大麻的使用就越多。也许更重要的是，我们的结果还表明，大麻的使用是压力和失眠严重程度更大增加的催化剂。我们的结果表明，在退伍军人中使用大麻可能既有好处，也有代价。具体地说，对于经历慢性睡眠问题的退伍军人来说，感知到的压力可能会变得不堪重负，而增加大麻使用减少压力的好处可能是以增加失眠症状为代价的。
Insomnia is highly prevalent among military veterans, with rates nearly double that of civilian populations. Insomnia typically co‐occurs with other psychological problems, including substance use (e.g. cannabis) and perceived stress. Much of the research focused on insomnia, stress and cannabis use explores cannabis as a sleep aid and a mechanism for stress relief. However, recent theoretical and empirical evidence suggests a dynamic interplay between insomnia, cannabis use and perceived stress, yet few longitudinal studies exist. Using a sample of 1105 post‐9/11 veterans assessed over four time points across 12 months, we used latent difference score modelling to examine proportional change between insomnia, perceived stress and cannabis use. Results revealed a complex interplay between all three constructs. In particular, we show that higher prior levels of insomnia are associated with greater increases in perceived stress, and greater prior levels of stress are associated with greater increases in cannabis use. Perhaps more importantly, our results also point to cannabis use as a catalyst for greater increases in both stress and insomnia severity. Our results suggest there may be both benefits and costs of cannabis use among veterans. Specifically, for veterans who experience chronic sleep problems, perceived stress may become overwhelming, and the benefit of stress reduction from increased cannabis use may come at the cost of increasing insomnia symptomology.
