The main goal of this paper is to translate, adapt and validate The Muscle Dysmorphic Disorder Inventory – MDDI in regular practitioners at the gym. The study included 170 subjects between men and women over 18 years old; they answer a questionnaire about sociodemographic data, on physical activity in the gym and about MDDI scale. The questionnaire was applied to participants individually, through an electronic form hosted on google.forms. It was observed that the MDDI presented a factorization similar to the original, with its three factors that interact with each other. Regarding to the convergence and divergence validity, both MDDI, considered a single factor, and its factors (DT = Desire for body size; IA = Appearance Intolerance; CF = Functional Impairment) were related to positive and negative self-esteem; however, correlational scores were higher with the negative selfesteem. It did not only corroborated the MDDI scale and its three-factor, which resemble to the American version and the German version of the same scale, but this construct also has an influence over psychological variables, in this case, the self-esteem. Thus, the scale would be useful in terms of assessing and developing practices with monitoring for exercise health.
