Validity and reliability evidence for the Behavioral Regulation in Sport Questionnaire with Romanian professional athletes

Abstract

Background. Despite the importance attributed to athletes' motivation in sports performance and well-being; no measures of motivation toward sport were found in the Romanian sport context. Objective. Grounded in self-determination theory, this research aimed to adapt and to gather validity and reliability evidence supporting the use of the Behavioral Regulation in Sport Questionnaire (BRSQ) in the Romanian sport domain. Method. The participants were 596 Romanian professional athletes (age: M =22.91, SD = 5.84; sports experience: M = 11.14, SD D 5.03), who 273 practiced individual sports and 323 team sports. They completed an online questionnaire survey assessing their perception of behavioral regulation, resilience and burnout in sport. Results. Confirmatory factor analysis supported the six-factor correlated model, which was invariant across age and sport. Correlations among latent factors configured a simplex structure, underpinning the self-determination continuum. Average variance extracted values from .50 to .70 endorsed convergent validity. Scores for heterotraitmonotrait ratio of correlations as high as .88, as well as 95% confidence intervals of each interfactor correlation that did not include 1.00 supported discriminant validity. Values over .70 for Cronbach's alpha, McDonald's omega and Raykov's coefficients showed a good level of reliability for each factor. Linear regression analysis revealed that while intrinsic motivation, integrated regulation and identified regulation positively predicted resilience, introjected regulation, external regulation and amotivation positively predicted burnout. Conclusions. The BRSQ is shown to be a valid and reliable measure of the six types of behavioral regulation in the Romanian sport context.
