Psychometric evaluation of the muscle appearance satisfaction scale in a Mexican male sample

PurposeThe purpose of this study was to determine whether the muscle appearance satisfaction scale (MASS) shows acceptable psychometric properties in Mexican bodybuilders.MethodsA total of 258 Mexican male bodybuilders were recruited. Two self-report questionnaires, including the MASS and drive for muscularity scale (DMS), were administered. Six models of the latent structure of the MASS were evaluated, using confirmatory factor analysis with maximum likelihood, considering robust Satorra–Bentler correction to estimate the fit of the models to the data.ResultsSimilar to the original MASS, the series of CFA confirmed that the Mexican version was well represented with the 17-item five-factor structure, which showed a good model fit [Satorra–Bentler Chi-square (109, n = 258) = 189.18, p < 0.0001; NNFI = 0.91; CFI = 0.93; IFI = 0.93; RMSEA = 0.05 (0.04, 0.07)]. Internal consistency was estimated with McDonald’s omega, which was acceptable for the MASS (0.88), and their subscales (0.80 to 0.89), except for muscle checking scale (0.77). Test–retest reliability analysis showed stability of the MASS total as well as of the subscale scores over a 2-week period (intraclass correlation coefficients = 0.75–0.91). Construct validity was demonstrated by a significant positive correlation between MASS and DMS results (r = 0.75; p = 0.0001). These results were similar to those of previous studies, which demonstrate the scale’s usefulness.ConclusionsOur results support the suitability of the MASS and its subscales to measure muscle dysmorphia symptoms in Mexican male bodybuilders.

Obesity in the State of Mexico: Interfaces and concurrences

In Mexico, from the eighties decade, various documents were made, and in which is specified the health care of the population, including obesity, documents which have been enriched by documents recently issued yet. However, as a health problem, overweight and obesity have become major challenges, placing the country at first place in health statistics on worldwide. This situation is identified in the different zones of the country, such as in the case of the State of Mexico. The objective of this work was to understand the relationship between emission of health programs, its contents, and the performance of the participants. The present paper was documentary, retrospective, analytical, and reflective kind. In a first step, different documents issued at national and regional level, characterized by including the regulatory framework for the care of obesity, were analyzed. Subsequently, the findings of four researches were considered, which made a link between the programs and their implementation. It can be stated that in Mexico, the health care and prevention of obesity are classified as an individual guarantee, expressed in the Political Constitution. As part of the national health policies, various documents establish the prevention of obesity; however by contrasting them with the results of the four studies, an inconsistency in implementation is identified. A closely monitoring of the process of implementation of preventive programs is required, to achieve the objectives posed in national health policies.
