Background Utilizing iterative and collaborative tools, Human-centered Design (HCD) facilitates the creation of tailored solutions for multifaceted issues by fostering empathy and a deep understanding of human behaviors. This paper presents insights gleaned from employing HCD tools to center communities in global health intervention development. Purpose The study team collaborated with community members in Dailekh, Nepal to co-design interventions to address harms associated with menstrual seclusion, known as chhaupadi. Research Design and Study Sample A Community Design Team, comprising 10 women representing various castes and ages convened for a four-day intervention co-design workshop in the community. A Community Validation Team, comprising 12 individuals from diverse occupational and caste backgrounds provided feedback on the interventions. Additionally, six village leaders participated in Key Informant Interviews to garner additional insights. Data Collection In the study’s initial “discovery” phase, the Community Design Team employed HCD tools to generate a nuanced understanding of the context, stakeholders, and community experiences. Subsequently, in the second “design” phase, the Community Design Team crafted interventions to address harms associated with chhaupadi. Results Invaluable lessons gained from this study underscore the necessity of crafting contextually suitable tools, checklists, and prompts for participants, allocating sufficient staff, time, and resources, and adapting to participants’ literacy levels and engagement preferences, whether through group or individual activities. Conclusions Reflecting on these insights, our experience suggests HCD offers promising tools to authentically and equitably involve participants with diverse backgrounds in articulating their own ideas for community-based solutions in Nepal. Health practitioners, researchers, and intervention development experts are encouraged to consider adopting HCD methodologies to prioritize community voices in devising solutions for complex health challenges.
