Abstract

The aim of the research was to exam the psychometric properties of the Dysfunctional Attitude Scale (DAS). Weissman and Beck have developed the DAS. The DAS consisted of 40 items with a 7 points scale. Translation to Farsi and back translation was done for the DAS. The Farsi version of the Scale was filled out by 300 high school students. The principle component factor analysis was used to exam the factor structure of the DAS. After considering the KMO index and Barttlet test, 3 to 7 factors solution was run to exam construct validity. The results revealed a five factor structure for the DAS. The factors named: Importance of the others judgment, need to satisfy others, feeling of risk, perfectionism, and need to attention. Also alpha index and convergent validity showed efficient psychometric properties for the DAS. In sum, the DAS is a reliable and valid scale for research job.
