Integrating digital health technologies for ecological validity in computational psychiatry: challenges and solutions

Abstract

Computational psychiatry offers promising opportunities for understanding and treating mental health disorders, yet achieving ecological validity—the accurate reflection of real-world experiences—remains a critical challenge. This perspective examines how digital health technologies can enhance ecological validity in computational psychiatry while addressing barriers in data collection, participant representation, validation, engagement, and methodological integration. We review key approaches, including digital phenotyping and adaptive design optimization, that enable more naturalistic data collection. However, achieving representative sampling and mitigating algorithmic biases remain unres..
