This measure is used to assess maladaptive belief patterns often associated with depressive vulnerability and cognitive distortions. The Dysfunctional Attitude Scale (DAS) is a self-report questionnaire developed to identify rigid, negatively biased assumptions that may be activated under stress.
The instrument contains 40 items and typically takes about 8 minutes to complete. It is commonly used in clinical and research settings to support case formulation, establish baseline cognitive style, and monitor change over time in psychotherapy. Original authors are A. T. Beck and A. N. Weissman.
Scores from the Dysfunctional Attitude Scale (DAS) are interpreted as an index of the degree to which dysfunctional attitudes are endorsed; results should be considered alongside clinical interview data and other assessment findings rather than used as a stand-alone diagnostic indicator.
