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.
