Abstract

The utility of traditional eating disorder measures in the assessment of muscularity-oriented disordered eating has been questioned. To address this limitation, the Muscularity-Oriented Eating Test (MOET) was recently developed and validated in a sample of U.S. college men. We aimed to develop a multicultural Spanish-language version of the MOET for use in Latin American samples and validate its use in a sample of Argentinian college men. Combined translation procedures were used to develop a version suitable for different Spanish-speaking populations. A total of 235 students (Mage = 23.47, SD = 5.61) participated in this study by completing a survey including the MOET. A sub-sample (n = 121) completed the MOET again after 1 week. A confirmatory factor analysis of a re-specified model of the original single-factor MOET, allowing for residual correlation between items associated to dietary rules (items 4-12), resulted in an adequate fit (χ2/df = 2.10, CFI = 0.94, TLI = 0.93, RMSEA 0.05 [90% CI = 0.04, 0.06] SRMR = 0.08). Further, the multicultural Spanish-language version of the MOET yielded evidence of internal consistency (omega = 0.83, 95% CI [0.79, 0.88], Cronbach's α = 0.83), a 1-week Intraclass Correlation Coefficient was considered for test-retest reliability (ICC = 0.82), item analysis, convergent validity with measures of eating disorder psychopathology, body dissatisfaction and weight-related behaviors, as well as for divergent validity with an unrelated construct. The availability of a multicultural Spanish-language version of the MOET may have utility in both clinical and research efforts related to muscularity-oriented disordered eating among Latino men.
