The Kessler-10 (K10) questionnaire was developed as a screening instrument for nonspecific psychological distress. Although it was validated using epidemiological samples, it is increasingly being used in clinical settings. We sought to determine whether the factor structure of the K10 as established in epidemiological samples, could be replicated in a sample of treatment seeking adults. We used confirmatory factor analysis to investigate two established models of the factor structure of the K10 in a sample of clinic attendees. Neither the single factor model of Kessler et al., Psychol Med. 2002;32:959-976, nor the multifactorial model of Brooks et al., Psychol Assess. 2006;18:62-70 fitted the data. Respecification of the Kessler et al. model to reduce item redundancy did not result in adequate fit. These findings call into question the construct validity of the K10 in treatment seeking samples, and the suitability of the scale for clinical settings may need to be reconsidered.
凯斯勒10项量表（K10）是作为一种非特异性心理困扰的筛查工具而开发的。尽管它已在流行病学样本中得到验证，但越来越多地被用于临床环境。我们试图确定在流行病学样本中建立的K10的因子结构是否能在寻求治疗的成年人样本中得到复制。我们使用验证性因子分析在一组门诊患者样本中研究K10因子结构的两种既定模型。凯斯勒等人（《心理医学》。2002年；32：959 - 976）的单因素模型和布鲁克斯等人（《心理评估》。2006年；18：62 - 70）的多因素模型均不适合该数据。对凯斯勒等人的模型进行重新设定以减少项目冗余，也未产生足够的拟合度。这些发现对K10在寻求治疗样本中的结构效度提出了质疑，可能需要重新考虑该量表在临床环境中的适用性。
