Abstract

Objective: Individuals with posttraumatic stress disorder (PTSD) and comorbid severe mental illness (SMI) are often underserved and undertreated. Empirical validation of commonly used measures of psychiatric symptoms in clinical practice, such as the Brief Psychiatric Rating Scale-Expanded (BPRS-E), is warranted in this vulnerable population. As such, this study sought to validate the factor structure and examine the psychometric properties of the BPRS-E among Veterans with comorbid PTSD and SMI.

Methods: The study sample included 126 Veterans with comorbid PTSD and SMI recruited for a larger randomized controlled trial. Confirmatory factor analysis was conducted to compare the fit of five potential factor structures. Construct validity was evaluated using Pearson correlation coefficients.

Results: Confirmatory factor analysis revealed that the four-factor model with 12 core items and the five-factor model with 15 items demonstrated a satisfactory fit. Construct validity evidence was provided for the BPRS-E total score via a moderate correlation with the Hamilton Depression Rating Scale, as well as weak but significant correlations with the Beck Depression Inventory and Clinician-Administered PTSD Scale.

Conclusions and implications for practice: This study is the first to examine the factor structure of the BPRS-E for individuals with PTSD and SMI. Our results support the BPRS-E as a reliable and valid assessment of psychiatric symptoms in this population. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

退伍军人创伤后应激障碍合并严重精神疾病简易评定量表的验证性因素分析。

目的：患有创伤后应激障碍（PTSD）和共病严重精神疾病（SMI）的个体往往得不到充分的服务和治疗。临床实践中常用的精神症状测量方法的经验验证，如简短精神病学评定量表-扩展（BPRS-E），在这一弱势群体中是有必要的。因此，本研究旨在验证创伤后应激障碍和重度精神分裂症合并的退伍军人BPRS-E的因素结构，并检验其心理测量特性。方法：研究样本包括126名合并创伤后应激障碍和重度精神障碍的退伍军人，进行更大规模的随机对照试验。采用验证性因子分析比较5个潜在因子结构的拟合性。采用Pearson相关系数评价结构效度。结果：验证性因子分析显示，包含12个核心条目的四因素模型与包含15个核心条目的五因素模型拟合良好。bpr - e总分与汉密尔顿抑郁评定量表存在中度相关性，与贝克抑郁量表和临床PTSD量表存在弱但显著的相关性，为其提供了结构效度证据。结论和实践意义：本研究首次探讨了PTSD和重度精神分裂症患者的BPRS-E的因素结构。我们的结果支持BPRS-E作为一个可靠和有效的评估精神症状的人群。（PsycInfo Database Record (c) 2025 APA，版权所有）。
