About the OPC Study

The OPC Study is evaluating whether making an online public commitment (OPC) to a behavioural goal influences goal attainment in relation to physical activity.

We are interested in recruiting individuals who are interested in being physically active, and are willing to set a SMART (Specific, Measurable, Achievable, Realistic &
