Assessment of the validity and reliability of the questionnaire of the motivational climate of physical activity in the aspect of the theory of self-determination

The article presents the results of assessing the validity and reliability of the questionnaire of the motivational climate of physical activity, which was developed on the basis of the theory of self-determination by E. L. Deci and R. M. Ryan and identifies the role of the motivational climate aimed at supporting autonomy in the choice of physical activity among students. The questionnaire is an adaptation of the short form of the questionnaire on the motivational climate in healthcare (Health Care Climate Questionnaire). The study was conducted on a sample of the Hong Kong population and amounted to 407 people. All respondents were informed about the purpose of the study and filled out a questionnaire, which was conducted in the form of an online survey. The statistical analysis verified the validity and reliability of the questionnaire, as well as the invariance of measurements depending on gender and age. The factorial validity of the scale was confirmed. The nomological validity was confirmed by its association with a conceptually related construction. The Cronbach's alpha coefficient and the consolidated reliability indicator indicate that the questionnaire is sufficiently reliable. The invariance of the scale measurements was also found depending on gender and age. The results of the study indicate that the questionnaire has adequate psychometric characteristics to measure the perception of a motivational climate that supports autonomy in the context of physical activity. The data can be used in future research as valid and reliable tools.
