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 Rōpū Mātanga Māori (Māori 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 Rōpū Mātanga Māori ensured accountability to the principles of Te Tiriti o Waitangi (Treaty of Waitangi) and kept Māori 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 Māori participants were included in the final guidelines. The Rōpū Mātanga Māori 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.

Self-harm rates are increasing globally and demand for supporting, treating and managing young people who engage in self-harm often falls to schools. Yet the approach taken by schools varies. This study aimed to explore the experience of school staff managing self-harm, and to obtain their views on the use of guidelines in their work. Twenty-six pastoral care staff from New Zealand were interviewed. Interviews were analyzed and coded using thematic analysis. Three themes emerged: The burden of the role; discrepancies in expectations, training, and experience; and the need for guidelines to support their work. This research, therefore, demonstrated a need for guidelines to support school staff to provide support around decision making and response to self-harm in the school environment.

Introduction Self‐harm is a significant public health issue affecting school communities, students, and families. The school is an ideal environment for early intervention and prevention. This study aimed to explore the views of young people and stakeholders on how school staff should support students who self‐harm in the context of developing accessible and acceptable guidelines. Methods The study was nested within a larger Delphi study conducted in New Zealand. Two panels were asked to provide reflection in open text boxes in two questionnaires on how school staff can support students who self‐harm. The youth panel included 22 participants between 16 and 25 years, and 81.8% identified as female and 18.3% as male. The stakeholder panel (e.g., school staff) included 27 participants over 25 years, and 63.0% identified as female, and 37.0% as male. The data were analyzed using thematic analysis to identify key themes. Results Eight themes were identified; (1) an approach that prioritizes trust, (2) an approach that recognizes students' agency, (3) an individually tailored approach, (4) a whole‐school approach, (5) an approach that recognizes role boundaries, (6) an approach that prioritizes safety, (7) a nonpunitive approach, and (8) an appropriately‐resourced approach. Conclusion The eight themes identified highlighted ineffective practices in response to self‐harm in schools. The eight themes provide solutions to these practices. Our findings highlighted four recommendations that address ineffective management approaches in response to students who self‐harm. These recommendations included using a student‐centered approach, a whole‐school approach, avoiding punitive approaches, and providing adequate resourcing to schools.
