BACKGROUND/OBJECTIVES: Several studies have indicated that stress is associated with common mental disorders, and work stress trebles the risk of developing them. However, a validated assessment tool for measuring and establishing psychological stress correlates in this group of clients remains unavailable. The objectives of the present study were to examine the psychometric properties of the Chinese version of the Perceived Stress Scale-10 (CPSS-10) on people with common mental disorders with different employment statuses and explore its correlates.
Two hundred and fifty-two participants with common mental disorders were recruited. The data were analysed through exploratory factor and confirmatory analyses to investigate construct validity. The convergent and discriminant validities were examined based on their correlation with other measures, while the internal consistency was estimated using Cronbach's α coefficient. A t-test was used to detect differences between groups. The CPSS-10 correlates were explored using multiple linear regression analysis.
Principal component analysis with varimax rotation yielded two factors, which accounted for 63.82% of the total variance, while confirmatory factor analysis confirmed its factor structure. The CPSS-10 had a positively moderate to strong correlation with other measures, thereby indicating its acceptable convergent and discriminant validities. The internal consistency ranged from acceptable to good for the two subscales and ten overall items, while the item-total correlation was adequate except for the seventh item. There were no group differences in gender nor employment status. Finally, the CPSS-10 predictors were studied.
The CPSS-10 is a reliable and valid instrument for people with common mental disorders with different employment statuses.
背景/目的：多项研究表明，压力与常见精神障碍有关，工作压力会使患常见精神障碍的风险增加两倍。然而，在这类患者群体中，仍没有经过验证的用于测量和确定心理压力相关因素的评估工具。本研究的目的是检验中文版感知压力量表10（CPSS - 10）在不同就业状况的常见精神障碍患者中的心理测量特性，并探索其相关因素。
招募了252名患有常见精神障碍的参与者。通过探索性因素分析和验证性分析对数据进行分析，以研究结构效度。基于其与其他测量指标的相关性检验收敛效度和区分效度，同时使用克朗巴哈α系数估计内部一致性。使用t检验检测组间差异。采用多元线性回归分析探索CPSS - 10的相关因素。
采用方差最大化旋转的主成分分析产生了两个因素，占总方差的63.82%，而验证性因素分析证实了其因素结构。CPSS - 10与其他测量指标具有正性的中度至强相关性，从而表明其具有可接受的收敛效度和区分效度。两个分量表和十个总体项目的内部一致性从可接受到良好不等，除第七项外，项目 - 总分相关性足够。在性别和就业状况方面没有组间差异。最后，对CPSS - 10的预测因素进行了研究。
CPSS - 10对于不同就业状况的常见精神障碍患者是一种可靠且有效的工具。
