Virtual Agents in DTx: Focusing on Usability and Therapeutic Effectiveness

Abstract

In the emergent field of digital therapeutics (DTx), this study examines the impact of virtual agent design on usability and therapeutic outcomes. Emphasizing the virtual agent’s role, our research highlights a marked therapeutic effect tied to the DTx’s developed parameters. Continuous usage, influenced by perceived usefulness, user attitudes, and intrinsic enjoyment, emerges as a crucial determinant for desired outcomes. The study finds anthropomorphism and agent likeability as pivotal factors in enhancing user experience and promoting sustained DTx use. Although focusing on mental health, particularly depression, the implications suggest varied results across DTx types. Given these insights, our findings advocate for a deeper exploration into agent-centric DTx designs, particularly in mental health applications. The nuances of user engagement with these therapeutic tools, especially in treating conditions like depression, demonstrate a diverse range of effects and underscore the importance of personalized approaches in digital therapeutics. This study’s outcomes not only shed light on the significant role of virtual agents but also call for continuous innovation and research in this evolving domain.
