Using the Behavioural Regulation in an Exercise Questionnaire (BREQ-2) in Central and Eastern Europe: Evidence of Reliability, Sociocultural Background, and the Effect on Sports Activity.

The factors influencing sports motivation create a complex system, integrating internal drivers, such as the love of sport and the need for competence, and external segments, such as the environment, institutions, or the media. In our research, we examined the sports motivation of students studying in higher educational institutions in five countries (Hungary, Romania, Serbia, Slovakia, and Ukraine) using the Behavioral Regulation in Exercise Questionnaire (BREQ-2). This research aims to explore the socioeconomic and institutional factors influencing students' sports motivation and the effect of sociocultural, demographical, motivational, and societal factors on the frequency of participating in sports. Based on factor analysis, instead of the original five factors, three factors could be detected in the sample: intrinsic and identified motivation, introjected motivation, extrinsic motivation, and amotivation. Based on the results, higher social status facilitates intrinsic motivation, while lower socioeconomic status facilitates extrinsic motivation and amotivation. The strongest effect is exerted by individual variables, of which intrinsic and identified motivation support regular physical activity as a significant factor among students in all countries. This can also be seen in the frequency of sporting activities, as the highest frequency of sports activity was detected among people with high intrinsic motivation.
