The number of elementary school students with Type 1 Diabetes (T1D) experiencing anxiety symptoms is increasing. Without proper treatment, anxiety symptoms in youth with T1D can impact health outcomes and adversely affect academic success. The Whole Student, Whole Community, and Whole Child (WSCC) model holds promise for developing preventative strategies to address the needs of students with T1D and anxiety symptoms. The underpinnings of the framework involve the community in partnership with the school and family, connections between health and academic achievement, and evidence-based school policies and practices. School nurses play an integral role in implementing the WSCC model. The purpose of this study was to explore school nurses' perceptions of school, family, and community partnerships for preventing anxiety symptoms in students with T1D. Specifically, school nurses described (1) the nature of existing collaborative partnerships in which they participate, (2) facilitators and barriers that exist when establishing and maintaining collaborative partnerships, (3) partnerships as a way to prevent or reduce anxiety symptoms in students with T1D, and (4) the impact of the COVID-19 pandemic on partnerships. Findings offer implications for establishing, maintaining, and improving partnerships between schools, families, and community providers for preventing anxiety symptoms in elementary students with T1D.
