Post-traumatic stress (PTS) is prevalent among military personnel. Knowledge of the risk and protective factors associated with PTS in this population may assist with identifying personnel who would benefit from increased or targeted support.
To examine factors associated with PTS among New Zealand military personnel.
For this cross-sectional study, currently serving and retired military personnel were invited to complete a questionnaire. The questionnaire included a measure of PTS (the Military Post-traumatic Stress Disorder Checklist; PCL-M), where scores ≥30 indicate the experience of significant PTS symptoms and scores ≥45 indicate a presumptive clinical diagnosis of post-traumatic stress. Potential risk and protective factors associated with PTS were examined using logistic regression modelling.
1817 military personnel completed the questionnaire. PCL-M scores were ≥30 for 549 (30%) participants and ≥45 for 179 (10%) participants. Factors associated with higher PCL-M scores were trauma exposure, older age, male sex, and Māori ethnicity. Factors associated with lower PCL-M scores were greater length of service, psychological flexibility, and better quality sleep.
PTS was found to be prevalent among New Zealand military personnel. The experience of trauma was strongly associated with PTS. However, factors such as psychological flexibility (the ability to adapt to changes in circumstances) and good sleep were protective, suggesting that these factors could be key targets for interventions designed to reduce PTS among military personnel in New Zealand.
创伤后应激（PTS）在军人中很常见。了解该人群中与 PTS 相关的风险和保护因素，可能有助于确定需要增加或有针对性支持的人员。
检查新西兰军人中与 PTS 相关的因素。
在这项横断面研究中，现役和退伍军人被邀请填写一份问卷。问卷包括 PTS 测量（军人创伤后应激障碍检查表；PCL-M），得分≥30 表示经历了明显的 PTS 症状，得分≥45 表示疑似创伤后应激诊断。使用逻辑回归模型检查与 PTS 相关的潜在风险和保护因素。
1817 名军人完成了问卷。549 名（30%）参与者的 PCL-M 得分≥30，179 名（10%）参与者的 PCL-M 得分≥45。与较高 PCL-M 得分相关的因素是创伤暴露、年龄较大、男性和毛利人种族。与较低 PCL-M 得分相关的因素是服役时间更长、心理灵活性更高和睡眠质量更好。
新西兰军人中 PTS 很常见。创伤经历与 PTS 密切相关。然而，心理灵活性（适应环境变化的能力）和良好睡眠等因素具有保护作用，这表明这些因素可能是针对新西兰军人 PTS 干预的关键目标。
