Entwicklung und Validierung einer deutschsprachigen Skala zur Erfassung der Veränderungsmotivation bei Essstörungen – The Stages of Change Questionnaire for Eating Disorders (SOCQ-ED)

Zusammenfassung

In der vorliegenden Studie wird die Entwicklung und Validierung des Stages of Change Questionnaire- Eating Disorders (SOCQ-ED) beschrieben, einem deutschsprachigen Messinstrument zur Erfassung der Veränderungsmotivation bei Essstörungen basierend auf dem Transtheoretischen Modell der Veränderung. Der SOCQ-ED wurde aus englischsprachigen Fragebögen entwickelt und erfasst die Veränderungsmotivation separat für die unterschiedlichen Symptombereiche der Anorexia und Bulimia Nervosa. Die psychometrischen Eigenschaften wurden anhand einer Stichprobe von N=63 Frauen mit Anorexia und Bulimia Nervosa bestimmt. Die Test-Retest-Reliabilitäten lagen zwischen rtt=0,42–0,78 (Mdn=0,56), Korrelationen mit dem Fragebogen zur Erfassung der Veränderungsmotivation zwischen r=0,21–0,32 und Korrelationen zu Maßen der Essstörungssymptomatik zwischen r=0,19–0,46. Insgesamt belegen die Ergebnisse eine ausreichende Reliabilität und Validität des 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.
