Psychometric Properties of Attitudes to Moral Decision-making Young Sport Questionnaire (AMDYSQ) for the Brazilian Sports Context

Abstract This research aimed to validate the Attitudes to Moral Decision-making in Youth Sport Questionnaire (AMDYSQ) for the Brazilian context using 2 studies. In Study 1, whose participants included 181 young athletes; an Exploratory Factor Analysis identified 3 factors consistent with the original study. Internal consistency indexes (Cronbach’s alpha) were acceptable for 2 factors (Cheating: α = 0.72; Unsportsmanlike conduct: α = 0.74), in the Fair victory factor this index was slightly below the acceptable (α =0.55). In Study 2, we sought to prove the factorial structure of AMDYSQ, with a new sample of 242 young athletes. We performed a Confirmatory Factor Analysis, where the results showed indicators of fit of the model according to the recommended in the literature: χ2 (62) = 99.820, p < 0.005, χ2/gl = 1.61, GFI = 0.94, AGFI = 0.91, TLI = 0.96; CFI = 0.97 and RMSEA = 0.05 (90% CI, 0.03 - 0.06). Thus, the study showed evidence of validity for the AMDYSQ for the Brazilian context; however, new validity studies should be performed with this instrument.
