Supporting healing after suicide loss: Development and validation of the first co-designed resource booklet for Indonesian suicide loss survivors

• First validated, culturally grounded postvention resource for Indonesian survivors • Co-designed through community-based participatory research design • Demonstrated strong content and face validity (S-CVI ≥ 0.98) • High suicide loss survivors’ satisfaction, usefulness, and recommendation rates • Practical tool to support recovery and reconnection after suicide loss This study reports the development and validation of Healing after Loss , the first co-designed resource booklet for Indonesian suicide loss survivors. It also examines survivors’ satisfaction, perceived usefulness, and likelihood of recommending the booklet. Guided by a community-based participatory approach, the research was carried out in two phases. Phase 1 involved content development informed by in-depth interviews with 16 suicide loss survivors and 15 grief support providers, supplemented by a review of grey literature. Phase 2 focused on validation, which included content evaluation by nine multidisciplinary experts and face validity assessment by 14 Indonesian suicide loss survivors. An iterative refinement process ensured that both survivor and expert feedback shaped the final design and content. Survivors and experts endorsed the booklet’s clarity, relevance, and cultural appropriateness. The final version demonstrated high validity (S-CVI = 0.98 for content; 0.99 for face validity). Suicide loss survivors reported high satisfaction, strong perceived usefulness, and a high likelihood of recommending the resource. The booklet shows potential as both a universal and indicated-level suicide-prevention tool, integrating psychoeducation to raise awareness and offering practical guidance to support recovery and social reconnection. Healing after Loss is the first survivor-informed, culturally grounded postvention resource in Indonesia. It provides an accessible tool for use across healthcare and community settings, addressing a critical gap in Indonesian postvention efforts and contributing to a more culturally diverse and globally relevant understanding of recovery after suicide bereavement.
