Internal consistency of the Sport Motivation Scale-II Questionnaire in the Brazilian context: potentialities and limitations

Abstract

The purpose of this paper was to analyze the internal consistency of the Sport Motivation Scale-II (SMS-II) questionnaire based on three studies with sports practitioners in the Brazilian college context. Methods: All the three studies i) were carried out with students enrolled in higher education and engaged in sports training by their institution (n1 = 304; n2 = 441; n3 = 310); ii) used SMS-II as an instrument for data collection; iii) used the online procedure for data collection. The Confirmatory Factor Analysis was performed and Cronbach's Alpha (α), McDonald's Omega (Ω), and the correlation between items were used to assess internal consistency. Results: As potentialities, five dimensions of the SMS-II presented high values of internal reliability (α and Ω > 0.60). As a limitation, the dimension of introjected regulation showed low reliability (α and Ω < 0.40) in the three studies conducted by our group. The exclusion of item 16 enabled an increase in alpha, but without achieving satisfactory reliability in Study 1 (α = 0.46) and Study 2 (α = 0.31). In Study 3, the exclusion of item 7 improved the internal reliability of the dimension (α = 0.43) also without reaching satisfactory values of internal consistency. It was not possible to identify a problematic item, given that each item had a different influence in the three studies. Conclusion: We found good values of validity and internal consistency for the Brazilian version of the SMS-II. However, we suggest attention to the introjected regulation dimension when using the instrument in the Brazilian college context.

Habilidades psicológicas e desenvolvimento de talentos no judô brasileiro

“…Foram elencadas 3 habilidades de cada fator, nas habilidades psicológicas apareceram a motivação, autoconfiança e resiliência, onde não houve grande diferença nas respostas dos entrevistados, o que coloca as 3 habilidades como habilidades importantes igualmente. Em detalhes, entender a motivação no esporte nos remete a entender alguns porquês na prática esportiva, onde para entendermos esses porquês precisamos compreender sobre persistência, preferências, intensidade, vigor, continuidade, características essas que estão atreladas as dimensões motivacionais (Barreira et al, 2022). Da mesma forma, no mundo atual, vemos que vivemos de uma forma onde existe a alta ocorrência de eventos aversivos no desenvolvimento dos indivíduos.…”
