Setting Goals and Accepting Challenges for Behavior Change—Analysis of Participants’ Interactions With a Digital Multiple Health Behavior Intervention: Mixed Methods Study

Our analyses suggest that, while goal-setting is theoretically grounded, and participants used Buddy in ways that suited their personal needs, this did not translate to measurable behavior change in the study population. The self-authored content showed how participants used the component and provided insights into how they articulate behavior change in terms of personal goals, challenges, strategies for action, motivation plans, and rewards. Future research should explore the conditions under which goal-setting may be more or less effective, to better understand its nuances and potential benefits.
