A Structured Literature Review on Conversational Agents that Empower Health Interventions

Conversational agents (CAs) are becoming increasingly popular in people's everyday lives. CAs are illustrative of recent technological advancements that have disrupted numerous domains, including healthcare, where they promise engaging, personalized, and effortless interactions that go further than static exchanges, and have the potential to improve users' behavior. To be effective as a vital instrument for enhancing users' well-being, CAs have to be designed for the task. However, research on how the CA should be designed to attain the intended behavior, specifically compliance, remains scant. Against this background, a systematic literature review was conducted, identifying 48 papers that cover CA features required for users to achieve the intended behavior in health interventions. Based on the results, this paper provides novel implications for future research.
