"I am a Physically Active Person!": A Randomized Controlled Trial Aimed to Increase Levels of Physical Activity Self-Definition and Physical Activity Among a Sample of Inactive Adults

Not Applicable

Completed

• Conditions: Physical Activity; Physical Activity Self-Definition

• Registration Number: NCT06509061
• Lead Sponsor: University of Manitoba

Brief Summary

This explanatory sequential mixed methods study investigated if an intervention can increase the physical activity identity and physical activity (PA) of inactive individuals. The intervention condition focused on increasing participant's physical activity self-definition (PASD) through educational sessions and group discussions on the five direct and indirect determinants of PASD (perceived enjoyment, perceived wanting, perceived commitment, perceived trying, perceived ability). The control condition was given general health behaviour education sessions. Researchers conducted interviews with some of the participants after the intervention was completed.

Primary Outcome Measures

Name	Time	Method
Physical Activity Self-Definition	Measured pre-intervention, 5 weeks later at intervention end and 4 weeks post intervention	Measured with a 4-item questionnaire using a 7-point Likert scale (1= strongly disagree; 7 = strongly agree)
