Vicarious Experience to Affect Physical Activity in Women: A Randomized Control Trial.

Area of Science:

• Behavioral Science
• Health Psychology
• Exercise Science

Background:

• Social comparison is a fundamental human behavior used for self-evaluation, information gathering, and motivation.
• The role of active peer models in influencing comparative thinking, particularly in the context of health behaviors, remains underexplored.

Purpose of the Study:

• To investigate the impact of a workplace peer modeling intervention on self-efficacy, motivation, and comparative thinking over 12 weeks.
• To determine if active peer interaction influences individuals' social comparison processes related to health behaviors.

Main Methods:

• A 12-week randomized pilot study with two groups: an intervention group (peer models, exercise prescription) and an attention control group (general health information).
• Participants (n=50) were assessed for changes in self-efficacy, motivation, and various dimensions of comparative thinking.

Main Results:

• No significant group-by-time interaction effects were observed for the primary outcomes.
• The intervention group showed increases in comparisons related to ability, opinions, future self, and modeling, while the control group showed decreases.

Conclusions:

• Active peer models may facilitate physical activity behavior change by positively influencing specific types of social comparison.
• Workplace interventions incorporating peer modeling show potential for promoting health behavior modification through social comparison mechanisms.
