Psychometric Properties of the Revised and Abbreviated form of the Turkish Version of the Dysfunctional Attitude Scale

Abstract

Dysfunctional attitudes are considered to be important risk factors in the onset and maintenance of depression. Thus, a psychometrically reliable and valid measure is necessary for understanding depression. The Dysfunctional Attitude Scale (DAS) is widely used and has good psychometric properties, but there is no consensus about its factor structure. To examine its psychometric properties and factor structure, a total of 885 individuals consisting of patients with depression and healthy controls were evaluated. After the sample was randomly divided into two subsets, exploratory and confirmatory factor analyses were performed. Then the DAS was abbreviated according to the factor profiles and theoretical background. Analyses indicated two factors, named Perfectionism/Achievement and Need for Approval/Dependency for the revised DAS . Reliability analyses revealed a good internal consistency, and the concurrent validity indicated significant correlations with the Beck Depression Inventory and the Automatic Thoughts Questionnaire.

Rumination, automatic thoughts, dysfunctional attitudes, and thought suppression as transdiagnostic factors in depression and anxiety

“…The Turkish version of the DAS was translated by Sahin and Sahin (1992a). The 16-item revised version of the psychometric instrument was developed by Batmaz and Ozdel (2016). The internal consistency for the DAS-R was α = 0.84 for the overall scale.…”

“…need for approval/dependency (NFA/D) and perfectionism/achievement (P/A). In Turkish form cronbach alpha value was found to be 0.84 for NFA/D subscale, 0.75 for perfectionism/achievement and 0.84 overall [23].…”

“…Dysfunctional attitude scale Turkish short form (DAS-R): Dysfunctional Attitude Scale is Likert type self reported scale and which includes 40 items scored between 1-7 developed to evaluate dysfunctional attitudes and beliefs [22]. Turkish validity and reliability study of the short form of the scale was performed by Batmaz ve Ozdel [23]. Its Turkish form includes 13 items scored between 1-7.…”

“…Moreover, as shortened scales are more acceptable for both the implementers and those who fill out the scale, the validity and reliability study of DAS' shortened form (DAS-R) was carried out by Batmaz and Özdel. 20 DAS-R consists of two factors as "perfectionism/aptitude (P/A)" and "need for approval /dependence (NFA/D)". The scale has a total of 13 items including the first 8 items in the dimension "P/A" and the last 5 items in the dimension "NFA/D".…”
