评估抑郁、焦虑和压力量表-21（DASS-21）在越南青少年中的内部一致性、潜在结构和聚合效度。2013年10月至2014年1月，在越南河内的1,745名高中生中进行了匿名自我完成的问卷调查。进行验证性因素分析以评估DASS-21的潜在结构。女孩和男孩之间的阶乘不变性进行了检查。计算Cronbach α和DASS-21因子得分与杜克健康档案青少年越南验证版（ADHP-V）的领域得分之间的相关系数，以评估DASS-21内部一致性和收敛效度。共有1，606/1，745（92.6%）名学生返回了问卷。其中，1，387名学生提供了完整的DASS-21数据。量表具有足够的内部一致性（Cronbach α：0.761 ~ 0.906）。一个四因素模型显示了最好的拟合数据。一般困扰因子中抑郁、焦虑因子的条目负荷显著，而应激因子的条目负荷较少（P<0.05）。DASS-21的收敛效度得到证实，其因子得分与ADHP-V心理健康相关领域之间的相关系数为中等（-0.47至-0.66）。DASS-21是可靠的，适用于评估常见的心理健康问题，特别是越南青少年的抑郁和焦虑症状。然而，它在这些青少年中检测压力的能力可能是有限的。这些结果值得进一步研究。
To assess the internal consistency, latent structure and convergent validity of the Depression, Anxiety and Stress Scale-21 (DASS-21) among adolescents in Vietnam. An anonymous, self-completed questionnaire was conducted among 1,745 high school students in Hanoi, Vietnam between October, 2013 and January, 2014. Confirmatory factor analyses were performed to assess the latent structure of the DASS-21. Factorial invariance between girls and boys was examined. Cronbach alphas and correlation coefficients between DASS-21 factor scores and the domain scores of the Duke Health Profile Adolescent Vietnamese validated version (ADHP-V) were calculated to assess DASS-21 internal consistency and convergent validity. A total of 1,606/ 1,745 (92.6%) students returned the questionnaire. Of those, 1,387 students provided complete DASS-21 data. The scale demonstrated adequate internal consistency (Cronbach α: 0.761 to 0.906). A four-factor model showed the best fit to the data. Items loaded significantly on a common general distress factor, the depression, and the anxiety factors, but few on the stress factor (p<0.05). DASS-21 convergent validity was confirmed with moderate correlation coefficients (-0.47 to -0.66) between its factor scores and the ADHP-V mental health related domains. The DASS-21 is reliable and suitable for use to assess symptoms of common mental health problems, especially depression and anxiety among Vietnamese adolescents. However, its ability in detecting stress among these adolescents may be limited. Further research is warrant to explore these results.
