M-PAC and Physical Activity Theory

The Multi-Process Action Control (M-PAC) framework for physical activity behaviour promotion is based off theoretical and empirical evidence from several decades of related research. Please see our dedicated M-PAC website for more specific information.



The BMED lab has a number of current projects on the go with the aim of testing M-PAC assumptions and refining its structure and effectiveness. Find out more about the studies and how to participate here.


For interested readers, we have highlighted key M-PAC papers and contributions related to its concepts below:
