DEMETRA: An ACT-Based Virtual Coach to Support Healthier Lifestyles in Overweight Pregnant Women-Protocol for a...

During pregnancy, women are more inclined to modify their habits and lifestyle to find a new balance and promote well-being for themselves and the child-to-be. However, the availability of nutritional and psychological support is often limited by stigma, geographic barriers, and a lack of services. Digital health tools are emerging as possible solutions to cover these needs. This study explores the acceptability, feasibility, and user experience of Demetra, a virtual coach based on Acceptance and Commitment Therapy (ACT), designed to promote healthy lifestyles and mental well-being. Fifty pregnant women will be enrolled in the feasibility study of the intervention. It starts with an educational part on the foundations of healthy eating and suggestions about lifestyle habits, followed by a six-week psychoeducational module. Content is delivered through text, audio, and video formats. User experience and engagement will be measured through validated questionnaires and semi-structured interviews. Psychological well-being will be evaluated both before and after the program. The intervention is expected to be well-received, with high levels of satisfaction and engagement, leading to a greater awareness of healthy behaviors, improved psychological flexibility, and enhanced overall well-being. Demetra offers an accessible solution to support women through the transformative experience of motherhood with a multidisciplinary and innovative approach.
