本研究旨在评估Kessler 6和K10（K-K6/K10）的韩语版本的心理测量学特性，以验证这两个量表与韩语版本的老年抑郁量表-简表（K-GDS-SF）和流行病学研究中心抑郁量表（K-CES-D）的关系，并提出适合韩国老年人群（n=331）的最佳临界分数。通过敏感性、特异性、受试者工作特征曲线和受试者工作特征曲线下面积评估心理测量学表现。根据Youden指数、最接近（0，1）和平衡评分估计截止评分。本研究发现，K-K6和K-K10似乎是稳健的筛选工具，K-CES-D和K-GDS-SF作为参考指标。韩国老年人口的截止分数建议为K-K6的12/13和K-K10的20/21。这项研究表明，K6和K10可以有效和可靠的筛选工具的心理困扰的韩国老年人，也可以用于在美国的韩裔美国老年人的临床和研究目的。
This study aims to assess the psychometric properties of the Korean versions of the Kessler 6 and 10 (K-K6/K10) to validate the two scales in relation to the Korean versions of the Geriatric Depression Scale-Short Form (K-GDS-SF) and the Center for Epidemiological Studies Depression Scale (K-CES-D) and to propose optimal cutoff scores appropriate for the elderly Korean population (n=331). Psychometric performance was assessed with sensitivity, specificity, receiver operating characteristic curves, and area under the receiver operating characteristic curve. Cutoff scores were estimated from the Youden index, the closest-to-(0,1), and the balanced score. This study found that the K-K6 and K-K10 appeared to be robust screening tools, with the K-CES-D and K-GDS-SF as reference measures. The cutoff scores for the Korean senior population are proposed to be 12/13 for the K-K6 and 20/21 for the K-K10. This study indicates that the K6 and K10 can be valid and reliable screening tools of psychological distress for Korean seniors and may also be used among the Korean American elderly in the United States for both clinical and research purposes.
