Co-design of "Baatcheet," a peer-supported, web-based storytelling intervention for young people with common mental health problems in India.

Background: Engaging with personal mental health stories has the potential to help people with mental health difficulties by normalizing distressing experiences, imparting coping strategies and building hope. However, evidence-based mental health storytelling platforms are scarce, especially for young people in low-resource settings.

Objective: This paper presents an account of the co-design of 'Baatcheet' ('conversation' in Hindi), a peer-supported, web-based storytelling intervention aimed at 16-24-year-olds with depression and anxiety in New Delhi, India.

Methods: Development comprised three stages: (1) establishing a logic model through consultations with a Young People's Advisory Group ( = 11) and a stakeholder reference group ( = 20); (2) elaborating intervention guiding principles and components through focus group discussions and co-design workshops ( = 42); and (3) user-testing of prototypes.

Results: The developmental process identified key stakeholder preferences for an online, youth-focused mental health storytelling intervention. Baatcheet uses an interactive storytelling website containing a repository of personal stories about young people's experiences of depression and anxiety. This is offered alongside brief support from a peer.

Conclusions: There are few story-based interventions addressing depression and anxiety for young people, especially in low-resource settings. Baatcheet has the potential to deliver engaging, accessible and timely mental health support to young people. A pilot evaluation is underway.
