Developing standards for the implementation of stepped care in child and youth mental health service settings: protocol for a multi-method, delphi-based study.

introductionCanadian youth mental health (YMH) systems have the potential to urgently tackle the mental health treatment gap currently impacting young people, and stepped care (SC) is one model that can address this need. The adoption of SC models can guide the development of better-connected YMH systems by simplifying transitions and care pathways. To do so requires robust standards that are co-created across stakeholder groups, including with lived experience experts, to ensure the effective implementation of SC models. METHODS AND ANALYSIS: This study aims to establish standards for implementing SC in Canadian child and YMH service settings by convening and developing a learning alliance (LA) of 65 individuals, translating guiding principles to standards via consensus methods (Delphi study), and operationalising and applying draft standards to three test ecosystems. Members of the LA will be recruited via snowball and purposive recruitment techniques to complete an e-Delphi study over three to four rounds until consensus is achieved. Participants will rank their agreement with including specific clause items in the final standard, and will be given opportunities to provide feedback and suggest revisions during each round. Comments will be analysed, scored and coded accordingly. Once consensus has been achieved, members of the LA will consider the application of these implementation standards in three settings that could benefit from SC. The protocol for this study was registered at Open Science Framework (https://doi.org/10.17605/OSF.IO/J5UNW). ETHICS AND DISSEMINATION: The protocol has been approved by the Centre intégré universitaire de santé et de services sociaux (CIUSSS) de l'Ouest-de-l'Île-de-Montréal-Mental Health and Neuroscience subcommittee. As part of the ethics approval, informed consent forms for all Delphi participants were created and distributed to participants ahead of the Delphi. This includes parental consent forms for all LA members participating in the study who are under the age of 18. On completion, the project will ultimately support the implementation of SC in diverse service systems and guide the development of a robust and connected mental health delivery system in Canada. The final standard will be shared with relevant government bodies and health planners and disseminated via academic and other platforms.
