The objectives of this study were to translate for the Portuguese language, describe the cross-cultural adaptation and identify the psychometric properties to the Brazilian young athletes of the Participation Motivation Questionnaire (PMQ). The original questionnaire was translated following international recommendations. Translated versions of the questionnaire were analyzes by a committee of experts. The committee used semantic, idiomatic, cultural and conceptual equivalences as criteria of analysis. The final version of the translated questionnaire was administered in a sample of 1517 young athletes (714 girls and 803 boys) aged 12 to 18 years-old. To identify the psychometric properties confirmatory factorial analysis with varimax rotation were completed. Cronbach’s alpha coefficient was used to assess the internal consistency of each factor of the PMQ associated to motivation for the practice of sport. After minor changes identified in the translation process, the committee of experts considered that the Portuguese version of the PMQ showed semantic, idiomatic, cultural and conceptual equivalences. The factorial analysis confirmed the structure of eight factors originally proposed, explaining 67% of the total variance and presenting reasonable values of internal consistency. The Cronbach-alpha ranged from 0.543 to 0.827. In conclusion, the translation, cross-cultural adaptation and psychometric qualities of the PMQ were satisfactory, thus enabling its application in future studies in Brazil.
