Objective:

To examine levels of engagement with digital intervention strategies, compliance with digital assessment procedures, and behavioral adherence to nondigital intervention strategies in a Digital Therapeutics (DTx) context, particularly focusing on how these elements interact.

Key Findings:

• Digital Therapeutics (DTx) can improve access to health behavior interventions but face challenges like lack of human support and technological complications.
• Engagement with digital interventions and compliance with assessment procedures can influence each other, potentially affecting the validity of the intervention.
• Positive affective responses to physical activity are linked to future engagement, but do not always ensure sustained participation, highlighting the need for ongoing support.

Interpretation:

The study highlights the importance of understanding the interplay between digital engagement and compliance in DTx, as well as the need for strategies such as personalized notifications and user-friendly interfaces to enhance user experience and reduce burden.

Limitations:

• The study's short duration may limit the generalizability of findings; future studies should consider longer testing periods.
• Potential biases in self-reported data could affect the validity of compliance and engagement measures; employing objective measures could mitigate this.

Conclusion:

Digital Therapeutics hold promise for enhancing physical activity engagement, but careful consideration of user experience and the relationship between engagement and compliance is crucial for effective implementation, necessitating further research.
