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

Area of Science:

• Psychology
• Psychiatry
• Clinical Psychology

Background:

• Cognitive distortions are hypothesized as central to anorexia nervosa and bulimia psychopathology.
• Empirical investigation of these hypotheses is limited.
• A lack of psychometrically sound assessment tools for these cognitions exists.

Purpose of the Study:

• To examine the psychometric characteristics of the Anorectic Cognitions Questionnaire (MAC).
• To provide a reliable and valid measure for assessing cognitive distortions in eating disorders.

Main Methods:

• Initial item development and refinement of the MAC.
• Assessment of concurrent validity.
• Exploration of the factor structure.
• Evaluation of internal consistency.

Main Results:

• The MAC demonstrated good concurrent validity.
• Three theoretically defined factors were empirically supported.
• The scale exhibited strong internal consistency.

Conclusions:

• The Anorectic Cognitions Questionnaire (MAC) is a psychometrically sound instrument.
• The MAC is suitable for assessing cognitive distortions in individuals with eating disorders.
• Further research can utilize the MAC to investigate the role of cognitive distortions in eating disorder psychopathology.
