Usage and Health Effects of Embodied Conversational Agents Among Older Adults

Eating Behavior Clinical Trial

Official title:
Usage and Health Effects of Embodied Conversational Agents Among Older Adults

Clinical Trial Summary

Rationale: Embodied Conversational Agents (ECAs), could be a highly effective medium to address health behaviour change among older adults. As compliance to health advice is important for positive health outcomes, successful design of persuasive ECAs can have huge health benefits. However, insights in the mechanisms underlying usage and health behaviour change via ECAs are lacking. Objective: The objective is to unravel the mechanisms behind the use of an ECA intervention, and understand the mechanism behind the observed behaviour change Study design: A randomized staggered-entry waitlist-controlled trial will be carried out. Study population: The study population consist of Dutch-speaking older adults, who live independently, are without partner, are retired, 65+ and possess basic computer skills. Intervention: The application PACO has been created for (and with) older adults with the goal to motivate them to improve their eating behaviour and decrease their feelings of loneliness. Main study parameters/endpoints: The main study parameters are use, loneliness, and eating behaviour. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Subjects are not exposed to any risks, nor have they any costs. They do have to fill in questionnaires and use the application. The duration and data collection moments are needed to gain a fine-grained understanding of the use, relationship development and health change process. For subjects, the main benefit is to gain insight in their health behaviour via the PACO-application. Although this might be experienced as confronting by some. The technology was developed based on sound theories, with input from the target group, so the investigators expect positive experiences and an improvement in participants loneliness and eating behaviour. However, this can only be proven after the study.
