Depression and anxiety are the most common mental health problems among adolescents. The Depression Anxiety Stress Scales for Youth (DASS-Y) is a newly developed instrument designed to assess these problems in adolescents.
The present study aims to evaluate the psychometric properties of the DASS-Y among Chinese adolescents.
A total of 326 secondary school students aged 14-18 years participated in the study. A convenience sampling method was adopted to conduct a test-retest of the DASS-Y among Chinese secondary school students. McDonald's omega, Cronbach's alpha, and intraclass correlation coefficient (ICC) along with their 95% were used to assess the internal consistency and test-retest reliability of the DASS-Y. Confirmatory Factor Analysis (CFA) evaluated the structural validity and convergent validity of the DASS-Y through the Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), Root Mean Square Error of Approximation (RMSEA), as well as Average Variance Extracted (AVE) and Composite Reliability (CR). Pearson correlation coefficients with the General Health Questionnaire-12 (GHQ-12), and the Pittsburgh Sleep Quality Index (PSQI) assessed criterion validity.
The CFA confirmed the validity the DASS-Y three-factor model consisting of depression, anxiety, and stress. The internal consistency reliability of the DASS-Y was found to be robust, with McDonald's omega and Cronbach's alpha values exceeding 0.8 for all dimensions across two measurements. The test-retest reliability was stable. The structural validity was reasonable and effective. Additionally, convergent validity is satisfactory, while criterion validity is also satisfactory. The three-factor model consisting of depression, anxiety and stress was confirmed through CFA.
The DASS-Y exhibits satisfactory psychometric properties among Chinese secondary school adolescents, reliably and appropriately screening for mental health issues such as depression and anxiety within this population. Consequently, it can be employed as a standard tool for routine mental health surveillance in secondary schools.
抑郁和焦虑是青少年中最常见的心理健康问题。青少年抑郁焦虑压力量表（DASS - Y）是一种新开发的用于评估青少年这些问题的工具。
本研究旨在评估DASS - Y在中国青少年中的心理测量特性。
共有326名14 - 18岁的中学生参与了该研究。采用便利抽样方法对中国中学生进行DASS - Y的重测。使用麦克唐纳ω系数、克朗巴哈α系数和组内相关系数（ICC）及其95%置信区间来评估DASS - Y的内部一致性和重测信度。验证性因素分析（CFA）通过比较拟合指数（CFI）、塔克 - 刘易斯指数（TLI）、近似均方根误差（RMSEA）以及平均方差抽取量（AVE）和组合信度（CR）来评估DASS - Y的结构效度和收敛效度。与一般健康问卷 - 12（GHQ - 12）和匹兹堡睡眠质量指数（PSQI）的皮尔逊相关系数评估了效标效度。
CFA证实了由抑郁、焦虑和压力组成的DASS - Y三因素模型的有效性。发现DASS - Y的内部一致性信度很强，两次测量中所有维度的麦克唐纳ω系数和克朗巴哈α系数值均超过0.8。重测信度稳定。结构效度合理有效。此外，收敛效度令人满意，效标效度也令人满意。通过CFA证实了由抑郁、焦虑和压力组成的三因素模型。
DASS - Y在中国中学生中表现出令人满意的心理测量特性，能够可靠且适当地筛查该人群中的抑郁和焦虑等心理健康问题。因此，它可作为中学常规心理健康监测的标准工具。
