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. 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. 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 and 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%. 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.

20项儿童青少年流行病学研究中心抑郁量表（CES-DC）是一种用于筛查抑郁症的工具，具有良好的心理测量学特性。本研究旨在从结构效度和收敛效度、内部一致性以及该量表较短的10项版本的同时效度方面检验其结构效度。这是一项横断面验证研究，纳入了来自西班牙昆卡的671名9至11岁的学童。使用20项CES-DC量表评估抑郁情况。我们选择了因子载荷最高的10个项目组成一个较短版本。考虑社会人口统计学、人体测量学、健康状况和生活质量变量来分析收敛效度和区分效度。对于结构效度，验证性因子分析显示20项CES-DC具有三因子潜在结构，而10项版本为单因子结构。用Cronbach's 系数和统计量测量的内部一致性，20项CES-DC为0.85，10项CES-DC为0.84。两个量表之间的组内相关系数为0.94。通过CES-DC两个版本与体重指数、腰围、健康状况和生活质量测量指标之间的相关系数和回归模型模型检验来检验收敛效度，结果相似。对于同时效度，一致性分析和ROC曲线显示10项CES-DC有等效的截断点。20项CES-DC将总共33.1%的样本分类为有抑郁风险，而10项CES-DC将30.4%的样本分类为有抑郁风险。本研究表明，CES-DC的20项和10项版本在学童中均具有良好的内部一致性和结构效度。因此，这个简短版本可以用作筛查抑郁症的可靠有效工具，在临床和学术环境中耗时更少且易于使用，可能会改善抑郁症的早期发现和干预。ClinicalTrials.gov标识符：NCT03236337。
