OBJECTIVE
The Depression Anxiety Stress Scales-21 (DASS-21) is the short version of a self-report measure that was originally developed to provide maximum differentiation between depressive and anxious symptoms. Despite encouraging evidence, the factor structure and other features of the DASS-21 are yet to be firmly established.
METHOD
A community sample of 417 participants and two clinical groups (32 depressive patients and 25 anxious patients) completed the Italian version of the DASS-21 along with several measures of psychopathology.
RESULTS
Confirmatory factor analyses suggested that the DASS-21 is a measure of general distress plus three additional orthogonal dimensions (anxiety, depression, and stress). The internal consistency and temporal stability of the measure were good; each DASS-21 scale correlated more strongly with a measure of a similar construct, demonstrating good convergent and divergent validity. Lastly, the DASS-21 demonstrated good criterion-oriented validity.
CONCLUSION
The validity of the Italian DASS-21 and its utility, both for community and clinical individuals, are supported.
目的
抑郁焦虑压力量表21项版（DASS - 21）是一种自陈式测量工具的简短版本，最初旨在最大程度地区分抑郁症状和焦虑症状。尽管有令人鼓舞的证据，但DASS - 21的因子结构和其他特征尚未得到确切确立。
方法
417名参与者的社区样本以及两个临床组（32名抑郁症患者和25名焦虑症患者）完成了意大利语版的DASS - 21以及几项精神病理学测量。
结果
验证性因子分析表明，DASS - 21是一种测量总体痛苦加上另外三个正交维度（焦虑、抑郁和压力）的工具。该测量工具的内部一致性和时间稳定性良好；每个DASS - 21量表与一个类似结构的测量指标相关性更强，显示出良好的聚合效度和区分效度。最后，DASS - 21显示出良好的以标准为导向的效度。
结论
意大利语版DASS - 21的效度及其对社区和临床个体的效用均得到了支持。
