智利大学生中焦虑症、抑郁症和压力症的发病率很高，需要标准化的诊断工具，以便能够及时干预这些障碍。本研究的目的是确定智利大学生抑郁、焦虑和压力缩写量表 (DASS-21) 的心理测量特性，从而验证该量表。样本由 484 名智利南方大学的学生组成，通过横截面相关设计进行随机抽样。通过探索性因素分析验证了结构有效性，产生了三因素结构，解释了总方差的 49.99%。并发有效性和发散有效性由 BAI、BDI-II 和 SCL-90 验证。使用 Cronbach's Alpha 发现 DASS-21 具有足够的可靠性和内部一致性。
The high rate of anxiety disorders, depression and stress detected in Chilean university students requires a standardized instrument of diagnosis, enabling timely intervention for these disturbances. The aim of this study was to determine the psychometric properties of the Abbreviated Scales of Depression, Anxiety and Stress (DASS-21) for Chilean university students, thus validating the scale. The sample consisted of 484 students of Universidad Austral de Chile selected through random sampling using a cross-sectional correlation design. Construct validity was verified by exploratory factor analysis which yielded a three-factor structure, explaining 49.99% of total variance. Concurrent and divergent validity was verified by the BAI, BDI-II and SCL-90. Adequate reliability and internal consistency of DASS-21 was found using Cronbach's Alpha.
