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.
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.
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.
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.
凯斯勒心理困扰量表（K10）是一个由10个项目组成的问卷，旨在测量心理困扰。本研究旨在使用来自中国大陆医疗保健专业人员的大样本，验证K10的因子结构及其信效度。
于2023年9月19日至10月20日通过匿名在线调查收集K10数据（总样本，N = 8602）。检验K10的内部一致性信度。进行探索性因子分析（N = 4301）和验证性因子分析（N = 4301）以验证结构效度。
探索性因子分析揭示了两个因子，即抑郁（DEP）和焦虑（ANX），它们共同解释了总方差的75.91%。验证性因子分析进一步支持两因子斜交模型为最佳拟合模型，优于单因子模型。K10的内部一致性为α = 0.952，而ANX和DEP的内部一致性系数分别为0.883和0.940。
K10是一个经过验证的简洁工具，在中国医疗保健专业人员中具有筛查心理困扰以及评估抑郁和焦虑症状的双重作用。
