Abstract

Purpose: The 20-item Center for Epidemiological Studies Depression Scale for Children and Adolescents (CES-DC) is an instrument for screening of depression with good psychometric properties. This study aimed to examine the construct validity in terms of structural and convergent validity, the internal consistency, and the concurrent validity of a shorter 10-item version of this scale.

Methods: This was a cross-sectional validation study including 671 schoolchildren aged 9–11, from Cuenca, Spain. Depression was assessed using the 20-item CES-DC scale. We selected the 10 items with the highest factorial loading for a shorter version. Sociodemographic, anthropometric, fitness, and quality of life variables were considered to analyse convergent and discriminant validity.

Results: For the structural validity, confirmatory factor analyses revealed a three-factor latent structure for the 20-item CES-DC and a single factor in the 10-item version. Internal consistency measured by Cronbach’s α and ω statistic were 0.85 for 20-item CES-DC and 0.84 for 10-item CES-DC. Intraclass correlation coefficient between the two scales was 0.94. Convergent validity was tested through the correlation coefficients and regression models between both either CES-DC versions with body mass index, waist circumference, fitness, and quality of life measures, which were similar. For the concurrent validity, concordance analysis and the ROC curve showed an equivalent cut-off point for the 10-item CES-DC. The 20-item CES-DC classified a total of 33.1% of the sample as at risk of depression, while the 10-item CES-DC classified 30.4%.

Conclusion: This study indicates that both the 20-item and 10-item versions of the CES-DC have good internal consistency and structural validity in schoolchildren. Therefore, this short version can be used as a reliable and valid instrument for screening depression that is less time consuming and easy to use in clinical and scholarly contexts, potentially improving early detection and intervention for depression.

流行病学研究中心儿童和青少年抑郁量表（CES-DC）西班牙语简版（10 个项目）的内部一致性和有效性

目的：由 20 个项目组成的儿童和青少年流行病学研究中心抑郁量表（CES-DC）是一种具有良好心理测量学特性的抑郁筛查工具。本研究旨在从结构效度和收敛效度、内部一致性和并发效度等方面对该量表的 10 个项目的简短版本进行检验。研究方法这是一项横断面验证研究，包括来自西班牙昆卡的 671 名 9-11 岁学龄儿童。抑郁采用 20 个项目的 CES-DC 量表进行评估。我们选取了因子载荷最高的 10 个项目制作了一个简短版本。我们还考虑了社会人口学、人体测量、体能和生活质量等变量，以分析其收敛性和鉴别性。结果如下在结构效度方面，确认性因子分析显示，20 个项目的 CES-DC 有一个三因子潜结构，而 10 个项目的版本只有一个因子。用 Cronbach's α 和 ω 统计量测量内部一致性，20 项 CES-DC 为 0.85，10 项 CES-DC 为 0.84。两个量表之间的类内相关系数为 0.94。通过两个版本的 CES-DC 与体重指数、腰围、体能和生活质量测量之间的相关系数和回归模型，对收敛效度进行了检验，结果相似。在并发效度方面，一致性分析和 ROC 曲线显示，10 项 CES-DC 的临界点相同。20项CES-DC将33.1%的样本归类为有抑郁风险，而10项CES-DC则将30.4%的样本归类为有抑郁风险。结论本研究表明，CES-DC 的 20 项和 10 项版本在学龄儿童中均具有良好的内部一致性和结构效度。因此，该简短版本可作为一种可靠有效的抑郁症筛查工具，在临床和学术背景下使用，耗时少，操作简便，有望提高抑郁症的早期发现和干预水平。试验注册：ClinicalTrials.gov 标识符：NCT03236337：NCT03236337。

期刊介绍： Depression and Anxiety is a scientific journal that focuses on the study of mood and anxiety disorders, as well as related phenomena in humans. The journal is dedicated to publishing high-quality research and review articles that contribute to the understanding and treatment of these conditions. The journal places a particular emphasis on articles that contribute to the clinical evaluation and care of individuals affected by mood and anxiety disorders. It prioritizes the publication of treatment-related research and review papers, as well as those that present novel findings that can directly impact clinical practice. The journal's goal is to advance the field by disseminating knowledge that can lead to better diagnosis, treatment, and management of these disorders, ultimately improving the quality of life for those who suffer from them.
