Abstract
Objective Self-harm is a major public health issue that significantly impacts communities, making early intervention and prevention paramount in addressing this public health issue. This study aimed to develop evidence-based, culturally responsive, safe, and practical guidelines to assist school staff in effectively supporting students who self-harm. Methods This Delphi study comprised of a five-step process, oversighted by a Ropu Matanga Maori (Maori clinical and cultural governance group), and drawing on the expertise and knowledge gained from existing literature, interviews with stakeholders, and two panels of experts (youth and stakeholders). The Ropu Matanga Maori ensured accountability to the principles of Te Tiriti o Waitangi (Treaty of Waitangi) and kept Maori processes central to the research aims. The panels completed two rounds of questionnaires, rating their endorsement of each statement. Statements rated as important or essential by 80% or more of both panels and Maori participants were included in the final guidelines. The Ropu Matanga Maori reviewed any remaining statements to determine inclusion. Results Following the five-step process, 305 statements were included in the guidelines. These statements provided guiding actions that endorsed communication, collaborative responsibility, and wellbeing and a student-centred approach. Conclusion The guidelines provide guidance to all school staff that is culturally responsive and safe, consensus-based, and evidence-based. It is informed by the voices and experiences of young people and those who support them.
