Psychometric propierties of the Muscle Appearance Satisfaction Scale (MASS) in Mexican men

The aim of this investigation was to evaluate the psychometric properties in a sample of Mexican men of Muscle Appearance Satisfaction Scale instrument (MASS; Mayville, Williamson, White, Netemeyer, & Drab, 2002), created for the purpose of assessing symptoms of muscle dysmorphia. The sample consisted of 521 male Mexican high school (n = 198) and university (n = 277) with an age range of 14-25 years (x¯ =19.06 S.D.=2.60).). The results show that the Mexican version has a total alpha of .91. Unlike the original scale had 5 factors, this version introduced a structure of four factors explaining 66.34% of the total variance, which were: 1) injury and muscular test (α = .90), 2) use substance (α = .83), 3) Unit to exercise (α = .80) and 4) muscle satisfaction (α = .77). It can be concluded that the MASS, where Mexican version, has good psychometric properties and is useful for assessing symptoms of Muscle Dimorphic Disorder (MDD) in Mexican men.

Psychometric properties of the Multidimensional Body Self Relations Questionnaire (MBSRQ)

Abstract La imagen corporal es considerada un constructo multidimensional que implica tres principales componentes: perceptual, subjetivo y conductual. El Multidimensional Body Self Relations Questionnaire (MBSRQ) es considerado como la medida mas completa de evaluacion de la imagen corporal, el cual consta de 69 items agrupados en 10 sub-escalas que miden evaluacion y orientacion de las apariencia. En poblacion mexicana existen pocos instrumentos que evaluen imagen corporal en hombres, por lo tanto el objetivo del presente estudio fue obtener las propiedades psicometricas del MBSRQ en poblacion masculina. La muestra estuvo conformada por 232 participantes de sexo masculino de nivel licenciatura provenientes de una institucion publica del area metropolitana de la ciudad de Mexico, con una edad promedio de 20.59 anos ( DE =2.65). El analisis de confiabilidad obtenido fue, en el test ( α = .88) y en el re-test (α = .86). La correlacion test-retest fue de r = .85. Se obtuvieron diez factores que explicaron el 64.48% de la varianza total, con alfas de .55 a .93. Los resultados muestran que el MBSRQ en hombres es un instrumento util para la evaluacion multidimensional de la imagen corporal debido a su estructura factorial, consistencia interna y fiabilidad test retest.
