• Registration Number: NCT02828956
• Lead Sponsor: University of Zurich

Brief Summary

By use of several questionaires, this study aimed at an investigation of the changes in motivation, symptoms, self-esteem and coping style in adolescent patients with anorexia nervosa.. The psychometric properties of the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ) and its relation to coping style and self-esteem were assessed. After a treatment period of nine months, clinical AN diagnosis and the body mass index (BMI) were re-assessed. Besides construct validity of the ANSOCQ, its predictive validity in terms of predicting the outcome of AN was assessed.
