Validation of a Spanish version of the Muscle Appearance Satisfaction Scale: escala de satisfacción muscular.

The psychometric properties of a Spanish version of the muscle appearance satisfaction scale (MASS; Mayville, Williamson, White, Netemeyer, & Drab, 2002) were examined using a sample of five hundred and sixty-one male weightlifters. Exploratory and confirmatory factor analyses suggested that the 19-item Spanish version of the MASS called the Escala de Satisfacción Muscular (ESM), was represented by five subscales similar to the original MASS. Internal consistency of the measure was good (α = .86-.95), and various measures of construct validity indicated that the ESM may be a useful measure of Muscle Dysmorphia symptoms among Spanish speaking populations.
