RESUMO

O compromisso desportivo como construto que explica a continuidade da prática desportiva e o seu modelo teórico que hipotetiza os factores que precedem  essa continuidade, apresentam-se como elementos bastante relevantes como forma de evitar o abandono desportivo. A análise da estrutura interna da versão Portuguesa do Sport Commitment Questionnaire (SCQ - questionário de compromisso desportivo) e comparação transcultural com a versão Espanhola, foram os principais objectivos do presente estudo. Participaram um total de 1702 jogadores de futebol, dos quais 850 Portugueses, entre os 11 e os 19 anos, e 852 da Catalunha, entre os 14 e 16 anos. Os resultados apoiam, em parte, a estrutura da versão portuguesa do SCQ com 6 factores e 28 itens. Destes factores, quatro - compromisso desportivo, divertimento desportivo, alternativas à implicação e coacções sociais - apresentam consistência interna suficiente. A análise do Funcionamento Diferencial dos Itens revela equivalência estrutural entre o modelo da versão Portuguesa e o modelo da versão Espanhola. A versão Portuguesa e Espanhola são mais próximas entre si, quando comparadas com os resultados da versão original. São necessários estudos que incluam diferentes desportos, idades e níveis competitivos para comprovar as características psicométricas da versão Portuguesa do SCQ.

Palavras-chave: compromisso desportivo, adaptação do Sport Commitment Questionnaire (SCQ) ao Português, funcionamento diferencial dos itens (DIF).

 

 

ABSTRACT

 Portuguese version internal consistency of the Sport Commitment Questionnaire (SCQ) and Differential Item Functioning (DIF)with the Spanish version

 The sport commitment as a construct that explain the continuity of sport practice and its theoretical model, that suggest which factors predicts this continuity, are relevant elements to avoid sport dropouts. The main goals of this study were the analysis of the internal consistency Portuguese version of the Sport Commitment Questionnaire (SCQ) and cross-cultural comparison with the Spanish version of the same instrument. Participants were1702 soccer players, 850 from Portugal, ranged from 11 to 19 years of age, and 852 from Catalonia, ranged from 14 to 16 years of age. Results provided some support for the SCQ Portuguese version with 6 factors and 28 items. Reliability analysis provided acceptable internal consistency for four scales: sport commitment, sport enjoyment, involvement alternatives and social constraints. The Differential Item Functioning (DIF) showed that the Portuguese structural model is equivalent to the Spanish structural model. The Portuguese and Spanish versions were more similar than when comparing with original version. Further studies with a wider age range, different genders, and other sports or competitive levels are necessary to confirm psychometric properties of the Portuguese version of the SCQ.

Key-Words: Portuguese adaptation of the Sport Commitment Questionnaire (SCQ), differential item functioning (DIF), sport commitment
