Persuasive system features in computer-mediated lifestyle modification interventions for physical activity.

Area of Science:

• Health Informatics
• Behavioral Science
• Digital Health

Background:

• Physical activity is crucial for lifestyle modification.
• Internet-based interventions show promise for motivating behavioral changes in physical activity.
• Persuasive System Design (PSD) offers a framework for understanding technology's role in behavior change.

Purpose of the Study:

• To identify and analyze the most frequently utilized persuasive system design features in computer-mediated physical activity interventions.
• To synthesize findings from existing literature on the application of PSD in promoting physical activity.

Main Methods:

• A systematic literature review was conducted using databases like PubMed, PsychInfo, and Web of Science.
• Intervention studies were analyzed and mapped against the persuasive systems design (PSD) features framework.
• Thirty-eight relevant articles were included in the analysis.

Main Results:

• The most frequently employed PSD features in physical activity interventions were tailoring, tunneling, reminders, trustworthiness, and expertise.
• The effectiveness of interventions varied, with the stage of change theory being a significant factor in persuasive success.
• Tailoring, reminders, trustworthiness, and expertise emerged as key components in successful interventions.

Conclusions:

• Specific persuasive system design features are critical for the success of computer-mediated physical activity interventions.
• Integrating features like tailoring, reminders, and trustworthiness, alongside stage-based approaches, can optimize digital health strategies for physical activity promotion.
