Abstract

Objectives

The Kessler Psychological Distress Scale (K10) is a 10-item questionnaire designed to measure psychological distress. The present study aimed to validate the factor structure of the K10 and its reliability and validity using a large sample from healthcare professionals in China mainland.

Methods

K10 data were collected in September 19 to October 20, 2023 via anonymous online survey (total sample, N = 8602).

The internal consistency reliability of the K10 was examined. Exploratory factor analysis (N = 4301) and confirmatory factor analysis(N = 4301) were conducted to validate the structural validity.

Results

Exploratory factor analysis revealed two factors, depression (DEP) and anxiety (ANX), which together accounted for 75.91 % of the total variance. Confirmatory factor analysis further supported the two-factor oblique model as the best fit, outperforming the one-factor model. The internal consistency of the K10 was α = 0.952, while the internal consistency coefficients for ANX and DEP were 0.883 and 0.940, respectively.

Conclusions

K10 is a validated and concise tool that serves a dual purpose of screening psychological distress and assessing depressive and anxiety symptoms among healthcare professionals in China.

凯斯勒-10量表在中国医疗保健专业人员中的心理测量特性的大规模验证

目的《凯斯勒心理困扰量表》（K10）是一份包含10个项目的心理困扰量表。本研究旨在通过对中国大陆医疗卫生专业人员进行大样本调查，验证K10量表的因子结构及其信度和效度。方法20123年9月19日至2023年10月20日，采用匿名在线调查方式收集数据10份（总样本，N = 8602）。对K10的内部一致性信度进行了检验。采用探索性因子分析（N = 4301）和验证性因子分析（N = 4301）验证结构效度。结果探索性因素分析显示，抑郁（DEP）和焦虑（ANX）两个因素共占总方差的75.91%。验证性因子分析进一步支持双因素倾斜模型为最佳拟合，优于单因素模型。K10的内部一致性系数为α = 0.952， ANX和DEP的内部一致性系数分别为0.883和0.940。结论sk10是一种经过验证且简洁的工具，可用于筛查中国卫生保健专业人员的心理困扰和评估抑郁和焦虑症状。
