The aim of this study was to analyze the psychometric properties of the Disposition to Cheating in Sport Questionnaire (CDED), derived from the Attitudes to Moral Decision-Making in Youth Sport Questionnaire (AMDYSQ-1, Lee, Whitehead and Ntoumanis, 2007). The sample included 110 adolescents (70 boys and 41 girls) with a mean age of 14.65 (Range: 10-19; SD = 2.09 years). The results show that the CDED, composed of the Acceptance of Cheating and Acceptance of Gamesmanship subscales, discriminates the population's variables acceptably and demonstrates an acceptable reliability and factorial validation
