新兴研究为发展中国家使用凯斯勒心理困扰量表提供了支持；然而，这项研究尚未扩展到南部非洲。本研究旨在评估凯斯勒量表在南非人群抑郁症和焦虑症筛查中的表现。该量表与综合国际诊断访谈（CIDI）一起被纳入南非压力与健康研究，这是一项具有全国代表性的家庭调查。 K10/K6 在检测普通人群的抑郁症和焦虑症方面表现出中等的辨别能力；接收者操作曲线下面积分别为 0.73 和 0.72。然而，这两种量表均未能满足我们高灵敏度和高阳性预测值的可接受标准。对种族/族裔反应差异的检查显示，K10/K6 [凯斯勒心理困扰量表 10 项 (K10) 和缩写的 6 项 (K6)] 在黑人群体中对抑郁和焦虑症的辨别能力 (0.71) 显着低于白人、有色人种和印度/亚洲人等少数种族/族裔群体 (0.78；p = 0.016）。 K10/K6（过去 30 天）与 CIDI（过去 12 个月）评估时间段的差异是本研究的一个显着局限性。建议使用临床诊断仪器进行额外的验证研究。版权所有 (C) 2011 John Wiley & Sons, Ltd.
Emerging research has provided support for the use of the Kessler Psychological Distress Scales in developing countries; however, this research has yet to be extended to southern Africa. This study sought to evaluate the performance of the Kessler scales in screening for depression and anxiety disorders in the South African population. The scales along with the Composite International Diagnostic Interview (CIDI) were included in the South African Stress and Health study, a nationally representative household survey. The K10/K6 demonstrated moderate discriminating ability in detecting depression and anxiety disorders in the general population; evidenced by area under the receiver operating curves of 0.73 and 0.72 respectively. However, both scales failed to meet our acceptability criteria of high sensitivity and high positive predictive value. Examinations of differences in responding by race/ethnicity revealed that the K10/K6 [Kessler Psychological Distress Scale 10-item (K10) and the abbreviated six-item (K6)] had significantly lower discriminating ability with respect to depression and anxiety disorders among the Black group (0.71) than among the combined minority race/ethnic groups of White, Colored, and Indian/Asian (0.78; p = 0.016). The difference in time period assessed on the K10/K6 (past 30 days) versus the CIDI (past 12 months) was a notable limitation of this study. Additional validation studies using clinician diagnostic instruments are recommended. Copyright (C) 2011 John Wiley & Sons, Ltd.
