Psychometric Properties of the Male Body Attitudes Scale-Revised Among Brazilian Men

摘要

Few self-report assessments have been validated for Brazilian men that address multiple dimensions of body dissatisfaction. Thus, the present study sought to validate the Male Body Attitudes Scale-Revised (MBAS-R) in Brazilian young men. A two-step approach was used in a sample of 644 Brazilian men, aged 18-35 years, to validate the MBAS-R using exploratory factor analysis (EFA, n = 211) and confirmatory factor analysis (CFA, n = 433). EFA replicated the original three-factor structure of the MBAS-R (muscularity, body fat, and height subscales) with 15 items. Two of the four CFA models tested yielded good fit indexes. One model upheld the original three-factor solution after excluding Items 7 and 14, while other model showed good fit after excluding Item 7 and the Height subscale. Both models demonstrated convergent validity and internal consistency (McDonald's omega =.82) and 2-week test-retest reliability were also strong. Results support the use of two adjusted versions of the MBAS-R for assessing body image in Brazilian college-aged men. Given the relevancy of height concerns for men, we suggest that the three-factor solution (i.e., muscularity, body fat, and height subscales) may be more suitable to assess relevant concerns among Brazilian men.
