Physical Activity, Physical Activity Self-Definition
Conditions
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.

Study design
Masking description
The participants were told that they were in one of two informational sessions; they were not told if they were in the intervention or the control group. Researchers sending the surveys to participants' emails were also blinded to the condition. Intervention facilitators who were presenting the material were necessarily aware of the condition.
Eligibility
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
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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) |
| ActiGraph Accelerometers | Measured pre-intervention, 5 weeks later at intervention end and 4 weeks post intervention | Weekly sedentary, light, moderate, and vigorous physical activity minutes were measured using accelerometers, worn at the hip for 7 day during waking hours. |
