The aim of the two research studies presented in this article was to test the reliability and validity of the Polish version of the Cognitive Distortions Scale (CDS). The relation of the CDS to psychological measures of well-being and other theoretically relevant variables was also explored.
Participants and procedure
Two correlational studies were conducted with psychology undergraduate students and their family members (n = 196 and n = 90, respectively). Participants completed a paper-pencil set of questionnaires that contained measures of cognitive errors (study 1) and scales related to perceived quality of life and psychological well-being (study 2).
Preliminary results supported the reliability of the Polish version of CDS (with Cronbach’s α .91 and .90) and convergent validity as indicated by correlations with maladaptive self-views and perceived relationship quality.
The Polish version of CDS appears to be a reliable and valid measure of cognitive distortions.
