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.
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.
Four different models of PTSD were tested using confirmatory factor analyses.
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.
Results supported the suitability of the DSM-5 4-factor model of PTSD among people with SMI.
创伤和创伤后应激障碍（PTSD）在患有严重精神疾病（SMI；例如精神分裂症、分裂情感障碍、双相情感障碍、难治性重度抑郁症）的个体中很常见，会导致功能障碍。先前的研究尚未评估 PTSD 检查表（PCL）在 SMI 人群中的因子结构。
本研究使用 PCL 对公共心理健康治疗部门筛查出的两个大型 SMI 样本进行 PTSD 评估，以检验 PCL 的因子结构。
采用验证性因子分析检验 PTSD 的四种不同模型。
结果表明，DSM-5 四因子模型（闯入、回避、麻木和过度警觉）具有最佳拟合度。此外，DSM-5 四因子模型显示出测量不变性。
结果支持 DSM-5 PTSD 四因子模型在 SMI 人群中的适用性。
