Validierung einer deutschsprachigen Fassung des Body Checking Questionnaire (BCQ) an Jugendlichen mit Anorexia und Bulimia Nervosa

Abstract

Body-related checking behavior, as a behavioral manifestation of a disturbed body image, fosters the development and maintenance of eating disorders. The Body Checking Questionnaire (BCQ) is the most commonly used questionnaire for measuring body-related checking behavior internationally. To date, validation studies are only available for adult populations. Therefore, the aim of this study was to statistically test the German-language version of the BCQ in adolescents. A total of N=129 female adolescents were examined, comprising n=57 with Anorexia Nervosa, n=24 with Bulimia Nervosa, and n=48 healthy female adolescents. A confirmatory factor analysis supports the subdivision of the BCQ into a general factor and the subfactors "overall appearance", "specific body parts" and "idiosyncratic checking", which was also found in the original version. The internal consistencies are good (α≥0.81), and the BCQ is able to differentiate well between adolescents with and without eating disorders. Significant correlations between the BCQ and other body image questionnaires point to a good convergent validity. The German-language BCQ thus constitutes a valid and reliable instrument for measuring body-related checking behavior among adolescents in clinical research and practice.

Psychometric Properties of the Body Checking Questionnaire (BCQ) and of the Body Checking Cognitions Scale (BCCS): A Bifactor-Exploratory Structural Equation Modeling Approach

“…Additional analyses supported the criterion-related validity of both questionnaires in relation to a variety of criterion measures. More specifically, findings showed that the G-factors from both questionnaires were highly correlated (positively or negatively) with the criterion measures in a direction that matched the results from previous studies (Calugi et al, 2006; Campana et al, 2013; Kachani et al, 2013; Reas et al, 2002, 2006, 2009; Steinfeld et al, 2017; Vocks et al, 2008). Additionally, moderate correlations were found for the S-factors of the BCQ and BCCS and criterion measures.…”

“…The results from these studies replicated the higher order CFA structure of the BCQ in samples of adolescents and/or adults. Additionally, several studies also supported the convergent validity of the BCQ factors with the BCCS factors (Haase, Mountford, & Waller, 2007; Mountford et al, 2006), and with measures of ED or DEAB (Calugi et al, 2006; Mountford, Haase, & Waller, 2007; Reas et al, 2009; Reas, White, & Grilo, 2006; Steinfeld et al, 2017; Vocks et al, 2008), body uneasiness (Calugi et al, 2006), body image avoidance (Calugi et al, 2006; Campana et al, 2013), social anxiety (Campana et al, 2013), social physique anxiety (Haase et al, 2007), depression (Steinfeld et al, 2017), and self-esteem (Steinfeld et al, 2017).…”

“…The BCQ has been validated in other languages, such as German (Steinfeld et al, 2017; Vocks, Moswald, & Legenbauer, 2008), Norwegian (Reas, Von Soest, & Lask, 2009), Portuguese (Campana, Swami, Onodera, da Silva, & Fernandes, 2013), and Italian (Calugi, Dalle Grave, Ghisi, & Sanavio, 2006). The results from these studies replicated the higher order CFA structure of the BCQ in samples of adolescents and/or adults.…”

“…A key question that remains concerning the factor structure of both of these questionnaires is related to whether the specific dimensions covered in each of them can really be combined into a global score reflecting either body checking behaviors (BCQ) or dysfunctional cognitions (BCCS). Although there is some evidence that the specific dimensions of the BCQ can be combined into a global score (e.g., Calugi et al, 2006; Campana et al, 2013; Reas et al, 2002, 2009; Steinfeld et al, 2017; Vocks et al, 2008), this remains to be empirically verified for the BCCS. However, when considering this question, it is important to keep in mind that the first-order factor correlations observed among the specific dimensions assessed by these instruments are quite high.…”

Häufigkeit von Komorbiditäten bei der stationären Behandlung von Essstörungen und Adipositas bei Mädchen und jungen Frauen

“…Weiterhin zeichnen Essstörungen sich durch Kontrollverhaltensweisen, wie z. B. Ordnungsliebe, Perfektionismus und Vermeidung von Risiken [28] aus, die ebenfalls mit anderen psychischen Störungen, wie der Zwangsstörung, Panikstörung, Agoraphobie und sozialen Angststörung assoziiert sein können [29]. Demgemäß berichten viele Studien Prävalenzen von bis zu 65 % für komorbide neurotische, Belastungs-und somatoforme Störungen bei Essstörungen.…”
