Psychometrische Überprüfung einer deutschsprachigen Fassung des Body Checking Questionnaire (BCQ)
Abstract
Zusammenfassung.Theoretischer Hintergrund: Körperbezogenes Kontrollverhalten stellt die behaviorale Manifestation eines gestörten Körperbildes dar. Fragestellung: Eine deutschsprachige Version des „Body Checking Questionnaire” (BCQ) soll hinsichtlich ihrer psychometrischen Kennwerte überprüft werden. Methode: 124 Frauen mit und 202 Frauen ohne Essstörungen sowie 64 Männer beantworteten neben dem BCQ weitere Fragebögen zu Ess- und Körperbildstörungen. Ergebnisse: Faktorenanalysen legen eine Ein-Faktor-Lösung nahe. Es ergab sich eine hohe interne Konsistenz, Test-Retest-Reliabilität und Differenzierungsfähigkeit zwischen Frauen mit und ohne Essstörungen sowie gesunden Personen beiderlei Geschlechts. Hohe Korrelationskoeffizienten des BCQ mit den weiteren eingesetzten Fragebögen indizieren eine gute konvergente Validität. Ebenso zeigt der BCQ eine ausreichende Veränderungssensitivität. Schlussfolgerungen: Der BCQ ist ein reliables und valides Instrument, dessen Einsatz sich sowohl im Forschungs- als auch im Praxiskontext empfiehlt.
Abstract.Background: Body checking is the behavioral manifestation of a negative body image. Objective: The psychometric properties of the German version of the „Body Checking Questionnaire” (BCQ) will be analyzed. Method: 124 females with and 202 without eating disorders and 64 males answered the BCQ and several other questionnaires on eating and body image disturbances. Results: Factor analyses indicate a one-factor solution. The BCQ proved to have a high internal consistency and test-retestreliability and could differentiate well between females with and without eating disorders as well as between the two sexes. High correlation coefficients of the BCQ with further instruments indicate a good convergent validity. Additionally, the BCQ demonstrates a sufficient sensitivity for change. Conclusions: The BCQ is a reliable and valid instrument which is recommended for use in research and practice.
