Abstract

Background: Trauma and posttraumatic stress disorder (PTSD) are common among individuals with serious mental illness (SMI; e.g., schizophrenia, schizoaffective disorder, bipolar disorder, treatment refractory major depressive disorder), with resultant functional impairment. Previous studies have not evaluated the factor structure of the PTSD Checklist (PCL) among persons with SMI.

Aims: This study evaluated the factor structure of the PCL in two large SMI samples from public mental health treatment sectors screened for PTSD using the PCL.

Methods: Four different models of PTSD were tested using confirmatory factor analyses.

Results: Results indicated that the DSM-5 4-factor model (intrusion, avoidance, numbing, and hyperarousal) had the best fit. Further, the DSM-5 4-factor model demonstrated measurement invariance.

Conclusions: Results supported the suitability of the DSM-5 4-factor model of PTSD among people with SMI.

重性精神病患者创伤后应激障碍（PTSD）的因子结构。

背景：创伤和创伤后应激障碍（PTSD）在严重精神疾病（SMI，如精神分裂症、分裂情感障碍、双相情感障碍、难治性重度抑郁症）患者中很常见，并因此导致功能障碍。目的：本研究评估了使用创伤后应激障碍核对表（PCL）筛查创伤后应激障碍的两个来自公共精神健康治疗部门的大型 SMI 样本的 PCL 因子结构：方法：使用确证因子分析对四种不同的创伤后应激障碍模型进行了测试：结果表明，DSM-5 的 4 因子模型（内隐、回避、麻木和过度焦虑）拟合度最高。此外，DSM-5 4因素模型还表现出了测量不变性：结论：研究结果表明，DSM-5创伤后应激障碍四因素模型适用于SMI患者。
