Validity and Reliability of the Catastrophic Cognitions Questionnaire-Turkish Version

Abstract

Aim: Importance of catastrophic cognitions is well known for the development and maintance of panic disorder. Catastrophic Cognitions Questionnaire (CCQ) measures thoughts associated with danger and was originally developed by Khawaja (1 992). In this study, it is aimed to evaluate the validity and reliability of CCQ-Turkish version. Material and Method: CCQ was administered to 250 patients with panic disorder. Turkish version of CCQ was created by translation, back-translation and pilot assessment. Fools demographic Data Form and CCQ Turkish version were administered to parcipants. Reliability of CCQ was analyzed by test-retest correlation, split-half technique. Cronbach's alpha coefficient. Construct validity was evaluated by factor analysis after the Kaiser-Meyer-Olkin (KM 0) and Bartlett test had been performed. Principal component analysis and varimax rotation were used for factor analysis. Results: Fifty-five point six percent (n=139) of the participants were female and fourty-four point four percent (n=111) were male. Internal consistency of the questionnaire was calculated 0.920 by Cronbach alpha. In analysis performed by split-half method reliability coefficients of half questionnaire were found as 0.917 and 0.832. Again spearmenbrown coefficient was found as 0.875 by the same analysis. Factor analysis revealed five basic factors. These five factors explained,566.2 of the total variance. Discussion: The results of this study show that the Turkish version of CCQ is a reliable and valid scale.
