Summary

This randomized control trial aims to investigate whether writing about personal values helps enhance motivation to engage in physical activity, relative to general self-reflective writing. This study will help to (1) assess whether values clarification leads to increased motivation to engage in physical activity, greater stability in motivation, and improvements in engagement in physical activity and valued action, relative to engaging in self-reflection, (2) determine if the impact of values clarification on these outcomes vary depending on context (e.g., positive/negative affect, psychological inflexibility, stressful events), (3) explore whether values clarification procedures that employ distinct relational frames (hierarchical, conditional, distinction, and deictic) differentially impact motivation to engage in physical activity, and daily engagement in physical activity, and (4) explore whether the impact of values clarification vary depending on baseline self-compassion and/or intrinsic/extrinsic motivation.

Conditions

  • Health-Related Behavior

Interventions

BEHAVIORAL

Values Clarification Mobile Application

Participants in the intervention group will be asked to answer a series of values clarification writing prompts related to physical activity once a day over four weeks.

BEHAVIORAL

Self-Reflection Mobile Application

Participants in the control group will be administered writing prompts in the same format and frequency as the values intervention, but with prompts focused on self-reflection related to physical activity.
