The purpose of the current study was to test the validity and reliability of a two-factor model of the Personal and Social Responsibility Questionnaire (PSRQ) and examine the relationships between perceptions of personal and social responsibility and intrinsic motivation in physical education. Participants were 253 middle school students who completed the questionnaires. The results from a confirmatory factor analysis and internal consistency suggest the two-factor PSRQ is valid and reliable for assessing students’ perceptions of personal and social responsibility in physical education. The correlational analysis suggests that participants with higher levels of personal and social responsibility were likely to enjoy physical education more. An important implication for teaching practice is that, to encourage all individuals to be intrinsically motivated to participate in physical education, physical education teachers need to empower students with choices and voices, focus them on effort and self-direction in physical education, and create a respectful and caring learning environment.
