Measuring the perception of the teachers’ autonomy-supportive behavior in physical education: Development and initial validation of a multi-dimensional instrument

This research aimed to develop and validate an instrument to assess the students’ perceptions of the teachers’ autonomy-supportive behavior by the multi-dimensional scale (Multi-Dimensional Perceived Autonomy Support Scale for Physical Education). The participants were 1,476 students aged 12- to 15-years-old. In Study 1, a pool of 37 items was generated based on past literature and feedback from students and academic experts. In Study 2, the factorial structure of the questionnaire was tested using exploratory and confirmatory factor analysis. The confirmatory factor analysis yielded a final 15-item three-factor solution of the Multi-Dimensional Perceived Autonomy Support Scale for Physical Education, covering organizational, procedural, and cognitive dimensions of perceived autonomy support. In Study 3, the incremental validity of the Multi-Dimensional Perceived Autonomy Support Scale for Physical Education was supported. The results provided initial evidence for the reliability and validity of the Multi-Dimensional Perceived Autonomy Support Scale for Physical Education, as well as its invariance across gender and age. Suggestions for the use of the scale and further research are discussed.
