While military service members are at risk forpain conditions, receipt of prescribed opioids is associated with a range of serious adverse outcomes. The goal of this study is to examine the association between pre-deployment personality traits and receipt of prescription opioids after return from deployment.
Data were drawn from the Readiness and Resilience in National Guard Soldiers (RINGS) cohort study, an ongoing study of post-deployment health. Participants (N = 522) completed baseline assessments one month prior to deploying to Iraq (2006-2007). At baseline, we assessed personality traits using abbreviated versions of the Personality Psychopathology Five scales from the Minnesota Multiphasic Personality Inventory-2. Follow-up assessments were conducted three months, one year, and two years post-deployment. The primary outcome was total amount of prescribed opioids dispensed from Department of Veterans Affairs outpatient pharmacies in the two-year period following soldiers' return from deployment. Unadjusted and adjusted negative binomial regression models examined the relationships of pre-deployment personality traits, demographics (age, gender, and rank), baseline trauma symptoms, deployment related risk factors (difficult living/working environment, deployment injury, combat exposure), and post-deployment trauma symptoms with post-deployment opioid prescribing.
Disconstraint, negative emotionality, and introversion/low positive emotionality were associated with receipt of more prescribed opioids over the two years after return from deployment. Personality traits measured at baseline remained statistically significantly after adjusting for all eight baseline and deployment risk factors of interest.
Understanding how pre-deployment personality traits contribute to post-deployment prescription opioid use could inform efforts to improve veterans' health.
虽然军人面临着疼痛状况的风险，但接受处方类阿片与一系列严重不良后果有关。本研究的目的是检验部署前人格特质与部署后接受处方类阿片之间的关系。
数据来自国民警卫队士兵准备和恢复力（RINGS）队列研究，这是一项对部署后健康的持续研究。参与者（N=522）在部署到伊拉克（2006-2007 年）前一个月完成基线评估。在基线时，我们使用明尼苏达多相人格测验-2 的人格心理病理学五量表的缩写版本评估人格特质。后续评估在部署后三个月、一年和两年进行。主要结局是退伍军人从部署返回后的两年内从退伍军人事务部门诊药房开出的规定类阿片的总剂量。未调整和调整后的负二项式回归模型检验了部署前人格特质、人口统计学特征（年龄、性别和职级）、基线创伤症状、与部署相关的风险因素（困难的生活/工作环境、部署伤害、战斗暴露）和部署后创伤症状与部署后阿片类药物处方之间的关系。
失调、负性情绪和内向/低正性情绪与从部署返回后的两年内接受更多规定类阿片有关。在调整了所有八项基线和感兴趣的部署风险因素后，基线测量的人格特质仍然具有统计学意义。
了解部署前人格特质如何导致部署后处方类阿片的使用，可以为改善退伍军人的健康状况提供信息。
