Antifragile Behavior Change Through Digital Health Behavior Change Interventions.

Area of Science:

• Digital Health
• Behavioral Science
• Intervention Design

Background:

• Digital health behavior change interventions (DHBCIs) aim to improve health behaviors but often fall short of their potential.
• A key limitation may be the lack of personalized support tailored to individual characteristics and goals.

Purpose of the Study:

• To propose antifragility as a framework for enhancing DHBCI design.
• To introduce antifragile behavior change as a strategy that leverages person-specific strengths to optimize behavior change outcomes.

Main Methods:

• Defining antifragility and antifragile behavior change.
• Proposing three core principles for designing antifragile DHBCIs: personalized guidance, embracing variance, and prioritizing user agency.
• Illustrating with a DHBCI design example.

Main Results:

• Antifragile behavior change focuses on selecting challenges that yield the most benefit by leveraging individual antifragilities.
• DHBCIs can be designed to foster antifragile behavior change through personalized guidance, exploration, and user agency.

Conclusions:

• Applying antifragility principles can lead to more effective and personalized DHBCIs.
• This approach offers a novel way to maximize benefits and minimize risks in users' health behavior change journeys.
