"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

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.

Inclusion Criteria:

• Must be insufficiently active (<150 minutes of moderate-vigorous PA per week)
• Scored below the mean in PASD
• Medically safe to participate in PA
• Intention to engage in PA over the next 6 weeks
