Confirmatory factor analysis and psychometric properties of the Spanish version of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales in early adolescents

- The 5-factor structure of the MBSRQ-AS was confirmed in early adolescents.
- In early adolescents the MBSRQ-AS presents excellent psychometric properties.
- MBSRQ-AS factors were associated with the Eating Attitudes Test.
- The MBSRQ-AS is able to detect differences between sexes.

The main aim of this study was to confirm the factorial structure of the Spanish version of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales in early adolescents from 12 to 14 years. The sample included 355 participants, 189 girls and 166 boys, with ages ranging from 12 to 14 years old. The original MBSRQ-AS 5-factor structure was confirmed, and the model showed a good fit to the data: Appearance Evaluation, Appearance Orientation, Body Areas Satisfaction, Overweight Preoccupation, and Self-Classified Weight. The internal consistency of the test scores was adequate. Girls had higher score s than boys on Appearance Orientation, Overweight Preoccupation, and Self-Classified Weight, and lower scores on Appearance Evaluation and Body Areas Satisfaction. This study confirms the factor structure of the MBSRQ-AS.
