Aims To evaluate the psychometric properties of the male
body dissatisfaction scale (MBDS) in Brazilian and Portuguese
university students; to present a reduced model of
the scale; to compare two methods of computing global
scores for participants’ body dissatisfaction; and to estimate
the prevalence of participants’ body dissatisfaction.
Methods A total of 932 male students participated in this
study. A confirmatory factor analysis (CFA) was used to
assess the scale’s psychometric properties. Multi-group
analysis was used to test transnational invariance and
invariance in independent samples. The body dissatisfaction
score was calculated using two methods (mean and
matrix of weights in the CFA), which were compared.
Finally, individuals were classified according to level of
body dissatisfaction, using the best method.
Results The MBDS model did not show adequate fit for
the sample and was, therefore, refined. Thirteen items were
excluded and two factors were combined. A reduced model
of 12 items and 2 factors was proposed and shown to have
adequate psychometric properties. There was a significant
difference (p\0.001) between the methods for calculating
the score for body dissatisfaction, since the mean overestimated
the scores. Among student participants, the
prevalence of body dissatisfaction with musculature and
general appearance was 11.2 and 5.3%, respectively.
Conclusions The reduced bi-factorial model of the MBDS
showed adequate validity, reliability, and transnational
invariance and invariance in independent samples for
Brazilian and Portuguese students. The new proposal for
calculating the global score was able to more accurately
show their body dissatisfaction.
