The Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (PID-5) was developed for the assessment of pathological traits in clinical settings. However, most research on the PID-5 is derived from nonclinical samples. To date, the comparability and generalizability of PID-5 constructs across nonclinical and clinical samples have not been adequately investigated. Therefore, we investigated the measurement invariance, five-factor structure, and factor correlations across clinical and nonclinical samples. The clinical sample ( n = 598) comprised patients with nonpsychotic disorders (81% women; mean age = 28.95), whereas a matched nonclinical sample ( n = 598) comprised community-dwelling individuals (81% women; mean age = 29.59). Measurement invariance was analyzed using a 13-step, two-group exploratory structural equation modeling approach. The results demonstrated acceptable psychometric properties for both samples and supported strong measurement invariance across the groups at the domain level.
人格障碍诊断与统计手册第五版量表（PID-5）是为临床环境下病理性特质的评估而开发的。然而，PID-5 的大多数研究都来自非临床样本。迄今为止，PID-5 结构在非临床和临床样本中的可比性和可推广性尚未得到充分研究。因此，我们研究了临床和非临床样本之间的测量不变性、五因素结构和因素相关性。临床样本（n=598）包括非精神病障碍患者（81%为女性；平均年龄=28.95），而匹配的非临床样本（n=598）包括社区居住者（81%为女性；平均年龄=29.59）。使用 13 步、两组探索性结构方程建模方法分析测量不变性。结果表明，两个样本都具有良好的心理计量学特性，并支持组间在域水平上具有很强的测量不变性。
