Factor structure and reliability of the Multidimensional Body–Self Relations Questionnaire in Chilean youth.

Abstract

The aim of this study was to ascertain the psychometric properties of the Multidimensional Body–Self Relations Questionnaire (MBSRQ) for a sample of youth in Chile. Cross-sectional survey was conducted with 451 participants. A non-clinical sample of adolescents and young adults between 15 and 25 years responded the MBSRQ and a sociodemographic questionnaire. Factorial analysis identified seven factors and provided empirical evidence that supports the use of these factors to evaluate body perception in Chilean youth. Scores exhibited good reliability in three factors (over 0.80) and acceptable reliability in the other four (over 0.70). Findings suggest that the Spanish MBSRQ was psychometrically sound, with 7 factors which are largely consistent with those identified in the original version and validation study of this scale. These factors possess sufficient internal consistency to make it plausible for use in research and screening with Chilean youth, and potentially useful as an adjunctive measure in the context of clinical decision making.
