Body image is considered a multidimensional construct that involves three main components: perceptual, subjective and behavioral. The Multidimensional Body Self Relations Questionnaire (MBSRQ) is considered the most comprehensive measure for assessing body image. The MBSRQ is a self-report inventory, which comprises 69 items grouped into 10 sub-scales that measure evaluation and orientation appearance. Only a few instruments in Mexican population exist that asses in a multidimensional way male body image The aim of this study was to obtain the psychometric properties of MBSRQ in male population. The sample was composed of 232 college male participants of a Public institution of Mexico City Metropolitan Area with an average age of 20.59 years (SD=2.65). Reliability analysis was obtained, at the test (α=.88) and re-test (α=.86). The test-retest correlation was r=.85. Ten factors were obtained, that explained 64.48%, of the total variance, with alphas of .55 to .93. The results show that the MBSRQ is a useful instrument in male population for multidimensional assessment of body image in men because of its factorial structure and excellent internal consistency and test retest reliability.
