Examining the Impact of a Self-compassion Intervention on Physical Activity Behaviour: An Efficacy Trial
Examining the Impact of a Self-compassion Intervention on Physical Activity Behaviour: An Efficacy Trial
The investigators plan to examine whether teaching people at risk for type two diabetes to use self-compassion (orientation to care for oneself during difficult situations) helps them self-manage and increase their physical activity. People at risk for type 2 diabetes will learn about their type 2 diabetes risk and strategies to increase their physical activity, which represents the recommended information that people at risk for type two diabetes should receive. In addition to this, some participants, but not all, will be taught to be self-compassionate in relation to their type two diabetes risk and their efforts to increase their physical activity. The investigators expect that people who receive the additional training about how to be self-compassionate will engage in more physical activity than people who do not and they will do so because of self-compassion's positive effect on aspects of self-management - adaptive reactions and a tendency to use strong self-management skills. This study is important for health promotion because it allows the investigators to determine whether they can improve how they currently help people prevent type 2 diabetes through engaging in physical activity.
The primary research objective of this efficacy trial is to determine if a self-compassion intervention can lead to a clinically significant increase in engagement in physical activity as compared to usual care (best behaviour change practice) in individuals with prediabetes.
Primary research question: Will a self-compassion intervention that augments usual care lead to greater increases in physical activity over 12 weeks post-intervention follow-up than usual care alone among people with prediabetes? Primary hypothesis: Self-compassion will lead to greater increases in physical activity than usual care at intervention-end and at 6- and 12-weeks.
Secondary research question: Will the effects of a self-compassion intervention on physical activity at 6- and 12-weeks post intervention be mediated by (i) negative affect (ii) physical activity self-regulatory skills and (iii) personal growth at baseline and intervention-end? Secondary hypothesis: The effects of self-compassion on physical activity behaviour at 6- and 12-weeks will be mediated by i) affect and ii) self-regulatory skill use assessed at baseline and intervention-end.
Tertiary research question: Will a self-compassion intervention that augments usual care lead to greater increases in other health-promoting behaviours (e.g., nutrition, stress management, seeking medical attention)? Tertiary hypothesis: Self-compassion will lead to greater increases in health-promoting behaviours than usual care at intervention end, 6-weeks and 12-weeks post intervention.
This efficacy trial is a single centre, randomized, active controlled, eight week intervention with baseline and follow-up assessment at intervention-end, 6- and 12-weeks post-intervention. It follows a quantitative-dominant, mixed-methods design. The investigators will compare the change in physical activity of community-dwelling people with prediabetes randomized to usual care in the form of behaviour change + attention (control condition) to that of participants who receive usual care + self-compassion training (intervention condition). The investigators will also examine potential mediators of the intervention (i.e., negative affect, physical activity self-regulatory skill use).
They will supplement this trial with interviews after follow-up testing with a subsample of self-compassion intervention participants. These interviews will provide feasibility information from participants (e.g., receptivity) as well as provide a qualitative assessment of the investigators' outcome measures.
