[Development and validation of a German questionnaire assessing motivation to change in eating disorders - the Stages of Change Questionnaire for Eating Disorders (SOCQ-ED)]. / Entwicklung und Validierung einer deutschsprachigen Skala zur Erfassung der Veränderungsmotivation bei Essstörungen - The Stages of Change Questionnaire for Eating Disorders (SOCQ-ED).

The present study describes the development and validation of a German questionnaire assessing motivation to change in individuals with eating disorders (Stages of Change Questionnaire-Eating Disorders, SOCQ-ED). The SOCQ-ED measures stages of change separately for each eating disorder symptom domain. Psychometric properties were assessed in a sample of N=63 women with Anorexia Nervosa or Bulimia Nervosa. Test-retest reliability ranged from rtt=0.42 to 0.78 (Mdn=0.56), correlations with the University of Rhode Island Change Assessment were between r=0.21 and 0.32 and correlations with measurements of eating pathology ranged from r=0.19 to 0.46. The results provide initial support for the reliability and validity of the SOCQ-ED.
