Development and Validation of a German Questionnaire Assessing Motivation to Change in Eating Disorders - The Stages of Change Questionnaire for Eating Disorders (SOCQ-ED)

Abstract

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.
