BACKGROUND The Dysfunctional Attitudes Scale, Form A (DAS-A), is the reference instrument for measuring dysfunctional attitudes which, according to Beck's cognitive theory, constitute the key vulnerability factor for depression. The psychometric properties of the Spanish version of the DAS-A have been examined in university students, but not in people with psychological disorders, despite being one of the most widely-used instruments in research and clinical practice of cognitive therapy for depression. The objective of the present study was to obtain validity evidence for the DAS-A in victims of terrorism with and without emotional disorders. METHOD The DAS-A's factor structure, internal consistency, and relationship with depression were analyzed in 196 victims of terrorism with emotional disorders and 280 victims without disorders. RESULTS In both samples, the DAS-A exhibited a structure with three correlated factors: Achievement-Perfectionism, Dependency-Need for Approval, and Autonomous Attitude. In general, the total scale and the subscales showed good or adequate indices of internal consistency (alphas and omegas = .60 - .89) and a relationship with depression ( r =.22 - .44). CONCLUSIONS The DAS-A provides reliable, valid measures of depressogenic dysfunctional attitudes in Spanish adults with emotional disorders and victims of terrorism.

恐怖主义受害者的功能失调态度：DAS-A 的有效性证据。

背景技术失调态度量表A 表(DAS-A) 是衡量失调态度的参考工具，根据贝克的认知理论，态度失调构成抑郁症的关键易感因素。尽管 DAS-A 是抑郁症认知治疗研究和临床实践中使用最广泛的工具之一，但西班牙版 DAS-A 的心理测量特性已经在大学生中进行了检查，但并未在患有心理障碍的人中进行过检查。本研究的目的是为有和没有情绪障碍的恐怖主义受害者获得 DAS-A 的有效性证据。方法 分析了 196 名有情绪障碍的恐怖主义受害者和 280 名没有障碍的受害者的 DAS-A 的因素结构、内部一致性以及与抑郁的关系。结果 在这两个样本中，DAS-A 都呈现出具有三个相关因素的结构：成就-完美主义、依赖-需要批准和自主态度。总的来说，总量表和子量表显示出良好或足够的内部一致性指数（α 和欧米茄 = .60 - .89）以及与抑郁症的关系（r = .22 - .44）。结论 DAS-A 为患有情绪障碍和恐怖主义受害者的西班牙成年人提供了可靠、有效的抑郁功能失调态度测量方法。89) 以及与抑郁症的关系 (r =.22 - .44)。结论 DAS-A 为患有情绪障碍和恐怖主义受害者的西班牙成年人提供了可靠、有效的抑郁功能失调态度测量方法。89) 以及与抑郁症的关系 (r =.22 - .44)。结论 DAS-A 为患有情绪障碍和恐怖主义受害者的西班牙成年人提供了可靠、有效的抑郁功能失调态度测量方法。
