NCT02785107

Brief Summary

The promotion of physical activity (PA) is paramount to public health, yet interventions in the social cognitive tradition have yielded negligible improvements. Two reasons for these results may be the over reliance on intention as the proximal determinant of behaviour and a lack of consideration of implicit/automatic determinants of PA. The purpose of this study was to apply Multi-Process Action Control (M-PAC), a framework centered on PA intention-translation and the gradual building of habit to examine PA change using a two-arm parallel design, randomized controlled trial.

Outcome Measures

Primary Outcomes (1)

  • GT3X+ Actigraph Activity Monitors (for measuring physical activity)

    Participants wear accelerometers for one week at baseline and at week eight to record their physical activity.

    Baseline to week eight

Secondary Outcomes (1)

  • Self-Report Behavioural Automaticity Index (self report, survey question)

    Baseline, week four, week eight

Other Outcomes (2)

  • Environmental Cues (self report, survey question)

    Baseline, week four, week eight

  • Temporal Consistency (self report, survey question)

    Baseline, week four, week eight

Study Arms (2)

Intervention

EXPERIMENTAL

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.

Behavioral: M-PAC Group

Control

NO INTERVENTION

Participants exercised on their own without receiving any instructions.

Interventions

M-PAC GroupBEHAVIORAL

Participants attended a workshop, completed a worksheet and received a booster phone call follow-up at week four.
