Abstract
IntroductionThe demand for adolescent mental health services has increased significantly in recent years, leading to excessive wait times for adolescents seeking mental health services and poor mental health outcomes. Timely access to mental health services is critical to reducing the risk of symptom chronicity and progression to mental disorder. A better understanding of whether and how interventions to reduce wait times impact mental health outcomes is needed to guide mental health policymakers and service planners in their approach to reducing wait times.Methods and analysisThe scoping review will use Arksey and O'Malley’s six-stage framework for scoping reviews and Rayyan to support screening, data extraction and evidence synthesis. The review will be conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. We will search the Cochrane Library, EBSCOhost, MEDLINE (Ovid), PsycArticles (Ovid), PsycINFO (Ovid), EMBASE (Ovid), Web of Science, ProQuest and Scopus databases for peer-reviewed texts published in English between 1 January 2000 and 28 February 2023. We will also search Google Scholar for additional grey literature. To be eligible for inclusion, studies must focus on adolescent populations aged 13–18 years and report on interventions to reduce wait times for any mental health service except crisis and emergency services. Title, abstract and full-text screening will be done by two reviewers. We will extract data describing the interventions and their effects on wait times and adolescent mental health outcomes, and we will identify strengths and limitations in the evidence base to inform recommendations for future research. A youth advisory group with lived experience of mental health difficulties will be consulted throughout the review process.Ethics and disseminationEthics approval is not required. Findings will be disseminated via peer-reviewed publications and presented at conferences.Study registrationThe protocol was registered with the Open Science Framework on 20 February 2023 (https://osf.io/qt4zy).
