A chat-bot based version of the WHO-validated intervention Self-Help+ for stress management: Co-Design and Usability Testing.

Background: Advancements in technology offer new opportunities to support vulnerable populations such as pregnant women and women diagnosed with breast cancer during physiologically and psychologically stressful periods.

Objective: This study aims to adapt and co-design the World Health Organization's Self Help Plus into a m-health intervention for these target groups.

Methods: Based on the ORBIT and CeHRes models, low-fidelity and high-fidelity prototypes were developed. Prototypes were evaluated by 13 domain experts from diverse sectors and 15 participants from the target groups to assess usability, attractiveness, and functionality through semantic differential scales, the uMARS questionnaire, and semi-structured interviews.

Results: Feedback from participants indicated positive perceptions of the m-health intervention, highlighting its ease of use, appropriate language, and attractive multimedia content. Areas identified for improvement include enhancing user engagement through reminders, monitoring features, and increased personalization. The quality of the content and adherence to initial protocols were positively evaluated.

Conclusions: This research provides valuable insights for future studies, aiming to enhance usability, efficacy, and effectiveness of the app suggesting a potential role of chat-bot delivered Self Help Plus intervention as a supportive tool for pregnant women and women with breast cancer diagnosis.
