The Model of Gamification Principles for Digital Health Interventions: Evaluation of Validity and Potential Utility

Area of Science:

• Digital Health
• Behavioral Interventions
• Gamification Principles

Background:

• Empirical studies on gamification for behavioral interventions are scarce.
• There's a need to evaluate gamification models for better integration into interventions.

Purpose of the Study:

• To examine the validity and reliability of a proposed gamification principles model for digital health.
• To inform the use of this model in Web- and mobile-based applications.

Main Methods:

• Evaluated 17 digital health interventions from PsyberGuide using 133 trained raters.
• Collected ratings on five gamification principles and correlated them with existing app metrics (PsyberGuide credibility, MARS, app store rating).

Main Results:

• Gamification ratings varied widely across apps, with acceptable inter-rater reliability.
• Gamification principles showed significant correlations with the Mobile App Rating Scale (MARS) and app store ratings.
• The 'supporting player archetypes' principle correlated with both MARS and app store ratings.

Conclusions:

• The gamification principles model is valid and potentially useful for digital health interventions.
• Gamification principles are not redundant with existing app measures and can improve user experience.
• This model can enhance engagement in digital behavioral health programs.
