Confirmatory factor analysis of the Drive for Muscularity Scale-S(DMS-S) and Male Body Attitudes Scale-S (MBAS-S) among maleuniversity students in Buenos Aires

Several studies have demonstrated that men express body dissatisfaction differently than women. Although specific instruments that address body dissatisfaction in men have been developed, only afew have been validated in Latin-American male populations. The aim of this study was to reassess thefactor structure of the Spanish versions of the Drive for Muscularity Scale (DMS-S) and the Male BodyAttitudes Scale (MBAS-S) in an Argentinian sample. A cross-sectional study was conducted among 423 male students to examine: the factorial structure (confirmatory factor analysis), the internal consistencyreliability, and the concurrent, convergent and discriminant validity of both scales. Results replicated thetwo factor structures for the DMS-S and MBAS-S. Both scales showed excellent levels of internal consis-tency, and various measures of construct validity indicated that the DMS-S and MBAS-S were acceptableand valid instruments to assess body dissatisfaction in Argentinian males.
