本研究前瞻性地评估了在住院PTSD治疗的退伍军人中，PTSD症状严重程度的治疗变化是否与出院后4个月使用大麻有关。样本由432名男性退伍军人患者组成（M年龄= 51.06岁，SD = 4.17），他们有PTSD的初步诊断，并被纳入VA住院康复计划。结果表明，治疗开始和出院之间的PCL-M评分变化水平较低，可显著预测4个月随访时大麻使用频率较高（p <0.05），即使考虑了治疗开始前2个月内治疗停留时间和大麻使用频率的影响。此外，事后分析显示，在控制相关协变量后，治疗期间PTSD回避/麻木和过度觉醒症状严重程度的变化较小，可显著预测4个月随访时大麻使用频率较高。值得注意的是，这些影响是大麻特有的，而在这一样本中检查的其他物质，包括酒精和阿片类药物中没有发现。研究结果的影响进行了讨论，关于现存的文献和未来的发展方向。
The present investigation prospectively evaluated whether treatment changes in PTSD symptom severity, among military Veterans in residential PTSD treatment, were related to cannabis use 4 months after discharge from residential rehabilitation. The sample was comprised of 432 male military Veteran patients (M-age = 51.06 years, SD = 4.17), who had a primary diagnosis of PTSD and were admitted to a VA residential rehabilitation program for PTSD. Results demonstrated that lower levels of change in PCL-M scores between treatment intake and discharge were significantly predictive of greater frequency of cannabis use at 4-month follow-up (p < .05), even after accounting for the effects of length of treatment stay and frequency of cannabis use during the 2 months before treatment intake. Furthermore, post hoc analyses revealed that less change in PTSD avoidance/numbing and hyperarousal symptom severity during treatment was significantly predictive of a greater frequency of cannabis use at 4-month follow-up, after controlling for relevant covariates. Notably, these effects were specific to cannabis and were not found for the other substances examined among this sample, including alcohol and opiates. Implications of the findings are discussed with regard to the extant literature and future directions.
