Validity, reliability, and factor structure of the Anorectic Cognitions Questionnaire

Abstract

Several authors have hypothesized cognitive distortion as central to the psychopathology of anorexia nervosa and bulimia. However, there have been few investigations of these hypotheses. Equally as important, psychometrically sound devices for assessing these cognitions are notably lacking. The purpose of this investigation is to examine the psychometric characteristics of the Anorectic Cognitions Questionnaire (MAC). This study reports on initial item development, initial concurrent validity, factor structure, initial item refinement, and internal consistency. Results indicated that the MAC has good concurrent validity, three theoretically defined factors were empirically supported, and the scale is internally consistent.
