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.

Conditions

Physical Activity Self-Definition; Physical Activity

Outcome Measures

Primary Outcomes (2)

• Physical Activity Self-Definition

  Measured with a 4-item questionnaire using a 7-point Likert scale (1= strongly disagree; 7 = strongly agree)

  Measured pre-intervention, 5 weeks later at intervention end and 4 weeks post intervention

• ActiGraph Accelerometers

  Weekly sedentary, light, moderate, and vigorous physical activity minutes were measured using accelerometers, worn at the hip for 7 day during waking hours.

  Measured pre-intervention, 5 weeks later at intervention end and 4 weeks post intervention

Study Arms (2)

PASD Intervention

EXPERIMENTAL

6 week 30-45 minute psychoeducation sessions that delivered content on the variables within the Physical Activity Self-Definition Model. The first session was an introductory session and each one that followed focused on one of the direct or indirect determinants of the model: perceived enjoyment, perceived wanting, perceived commitment, perceived trying, perceived ability (all relating to physical activity). Group activities such as worksheets and discussion were carried out during the session.

Other: Physical Activity Self-Definition

Attention Control

ACTIVE COMPARATOR

6 week 30-45 minute educational sessions that delivered content on general health behaviour. After the introductory session, each week, one of five general health behaviours were covered: balanced diet, sleep, reducing sedentary behaviour, mental/spiritual health and self-compassion/cultivating positive health behaviours. Group activities such as worksheets and discussion were carried out during the session.

Other: Control

Interventions

Physical Activity Self-Definition OTHER

6 week behavioural change program designed to increase PASD and PA

PASD Intervention

Control OTHER

6 week program designed to as an attention control, delivering content on general health behaviour.

Attention Control

You may qualify if:

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: TRIPLE
• Who Masked: PARTICIPANT, INVESTIGATOR, OUTCOMES ASSESSOR
• Masking Details: 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.
