The psychometric properties of the Depression Anxiety Stress Scales (DASS; Lovibond & Lovibond, 1995a) were examined in depressed psychiatric hospital samples.
Three studies administered the DASS and other symptom measures at admission and discharge to consecutive adult hospital patients with a primary diagnosis of depression. Study 3 aimed to address problems with the DASS by extending the response options.
Study 1 found that the DASS had good reliability and validity, was moderately sensitive to change, but the Depression Scale exhibited a ceiling effect. In Study 2, confirmatory factor analysis supported a three-factor structure and the DASS continued to demonstrate good psychometric properties, but the ceiling effect was replicated. Study 3 found that by extending the response scale to include an additional option, the factor structure of the instrument as a whole was maintained, the sensitivity to treatment was increased, but the ceiling effect was only marginally reduced.
The psychometric properties of the DASS were sound in clinically depressed samples, but the Depression Scale exhibited a ceiling effect that could not be resolved with minor changes to the scale. Suggestions for revisions of the DASS are made.
在抑郁的精神病院样本中检验抑郁焦虑压力量表（DASS；洛维邦德和洛维邦德，1995a）的心理测量特性。
三项研究对连续入院和出院的以抑郁症为主要诊断的成年住院患者施测了DASS及其他症状测量工具。研究3旨在通过扩展反应选项来解决DASS存在的问题。
研究1发现，DASS具有良好的信度和效度，对变化有中等程度的敏感性，但抑郁量表表现出天花板效应。在研究2中，验证性因素分析支持三因素结构，DASS继续表现出良好的心理测量特性，但天花板效应再次出现。研究3发现，通过将反应量表扩展以纳入一个额外选项，该工具整体的因素结构得以维持，对治疗的敏感性增加，但天花板效应仅略有降低。
DASS的心理测量特性在临床抑郁症样本中是可靠的，但抑郁量表表现出一种天花板效应，无法通过对量表进行微小改动来解决。文中给出了对DASS进行修订的建议。
