Validity and Reliability of the Catastrophic Cognitions Questionnaire-Turkish Version

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 (1992). 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. Socio-demographic Data Form and CCQ Turkish version were administered to participants. Reliability of CCQ was analyzed by test-retest correlation, split-half technique, Cronbach%u2019s alpha coefficient. Construct validity was evaluated by factor analysis after the Kaiser-Meyer-Olkin (KMO) 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 spearmen-brown coefficient was found as 0.875 by the same analysis. Factor analysis revealed five basic factors. These five factors explained %66.2 of the total variance. Discussion: The results of this study show that the Turkish version of CCQ is a reliable and valid scale
