System mapping to strengthen youth crisis response: findings from a multi-county California pilot.

Youth suicide is a pressing public health concern requiring coordinated, cross-sector responses. This research presents findings from a pilot initiative involving ten California counties that used a multi-site participatory system mapping design to assess and strengthen youth crisis reporting and response systems. Funded through the Children and Youth Behavioral Health Initiative and supported by the California Department of Public Health, the pilot used visual tools to identify gaps, clarify roles, and promote shared understanding across sectors. System maps focused on six key components of crisis systems, supporting communities in developing targeted action plans and promoting system accountability. Results demonstrated that the mapping process catalyzed improvements in follow-up care, school and hospital coordination, and postvention practices. Challenges included navigating structural differences among partners and sustaining engagement. Findings suggest that system mapping is a replicable and equity-centered approach to the development of public health infrastructure.
