Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The limitations of applying social cognitive models to understand physical activity (PA) have led to the emergence of several new PA models within the past decade. The Multi-Process Action Control (M-PAC) is a comprehensive PA model that proposes intention is established from outcome expectations, perceived capability, and opportunity, then the success of translating this to behavior depends on affective judgments and behavioral-regulation. Over time, M-PAC proposes that behavior is can become maintained through the formation of identity and habit. The purpose of this study was to investigate the trajectory of change of these M-PAC constructs across time in a randomized controlled trial. Participants (n=85) were inactive new gym members and were randomized into a control (n=41) or intervention (n=44) group. The intervention group attended a workshop and received a booster phone call follow-up at week four. Measures for both groups included accelerometry and M-PAC at baseline and eight week follow-up.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control

No Intervention: Control Participants exercised on their own without receiving any instructions.

Group Type NO_INTERVENTION

No interventions assigned to this group

Intervention

Those who were randomized into the intervention group attended a workshop where the PI delivered a presentation that focused on establishing a preparatory exercise habit by using the M-PAC approach and proposed habit model. Participants were then provided with instructions on completing their exercise plan sheet.
