Despite a central role for dysfunctional attitudes in cognitive theories of depression and the widespread use of the Dysfunctional Attitude Scale, form A (DAS-A; A. Weissman, 1979), the psychometric development of the DAS-A has been relatively limited. The authors used nonparametric item response theory methods to examine the DAS-A items and develop a briefer version of the scale. Using DAS-A data obtained from depressed participants enrolled in 2 large depression treatment studies (N=367), the authors developed a 9-item DAS form (DAS-SF1). In addition, because 2 versions of the DAS are needed for certain study designs, they also developed a 2nd short version (DAS-SF2). These short forms were highly correlated with the original 40-item DAS-A (rs ranged from .91 to .93), exhibited change similar to that of the DAS-A over the course of treatment, were moderately correlated with related self-report assessments, predicted concurrent depression severity, and predicted change in depression from before to after treatment. Taken together, the authors believe the DAS-SF1 and DAS-SF2 provide an efficient and accurate assessment of dysfunctional attitudes among depressed individuals.
尽管功能失调性态度在抑郁症认知理论中起着核心作用，且功能失调性态度量表A版（DAS - A；A. 魏斯曼，1979年）被广泛使用，但DAS - A的心理测量学发展相对有限。作者使用非参数项目反应理论方法来检验DAS - A的项目，并开发了一个更简短的量表版本。利用从参与两项大型抑郁症治疗研究的抑郁症患者中获得的DAS - A数据（N = 367），作者开发了一个9项的DAS版本（DAS - SF1）。此外，由于某些研究设计需要两个版本的DAS，他们还开发了第二个简短版本（DAS - SF2）。这些简短版本与最初的40项DAS - A高度相关（相关系数r范围从0.91到0.93），在治疗过程中表现出与DAS - A相似的变化，与相关的自我报告评估中度相关，预测了当前的抑郁严重程度，并预测了治疗前后抑郁的变化。综合来看，作者认为DAS - SF1和DAS - SF2为评估抑郁症患者的功能失调性态度提供了一种有效且准确的方法。
