Method: In this study, 148 healthy adults (Mean age = 44.70, 96.6% women) and 89 chronic fatigue patients (Mean age = 47.39, 97.8% women) filled out questionnaires related to behaviour regulation style (TSRQ ¨C PA) and physical activity. Results: The confirmatory factor analysis adjustment indices of a two-factor structure (Autonomous Regulation scale and Controlled Regulation scale) of the TSRQ-PA were satisfactory and internal consistency estimates were acceptable for both factors. A higher degree of autonomous behaviour regulation was significantly associated with higher levels of physical activity. Conclusion: These findings provide support for the validity and reliability of the TSRQ ¨C PA for measuring behaviour regulation style for engaging in physical activity, in different settings. %K physical activity %K motivation %K behaviour regulation style %K validity %K reliability %U http://pch.psychopen.eu/article/view/32/18
