The perspectives of stakeholders directly affected by mental health services for autism spectrum disorder (ASD) are essential for the quality of these services. However, it is crucial that these perspectives are informed by the best available evidence and adapted to the local context. This study aims to analyse barriers related to mental health services for children and adolescents with ASD from the perspective of families and caregivers, considering social, racial and gender aspects.

Three steps will be taken: stakeholder engagement through an online meeting to refine the research question and understand the magnitude of the problem; (b) qualitative evidence synthesis using five databases and grey literature to identify studies that have collected and analysed qualitative data on barriers to mental health services for children and adolescents with ASD in Brazil. Only studies conducted in Brazil that consider the perspectives of family members and caregivers will be included. (c) A citizen panel with families of children and adolescents with ASD will be used to discuss and validate the synthesis findings.

We will provide a set of evidence-informed and stakeholder-experienced barriers to mental health services for children with ASD in Brazil. This represents an effort to engage stakeholders in evidence descriptions to inform policy. We plan to disseminate the findings through various means, including peer-reviewed journal publications, presentations at national conferences, invited workshops and webinars, patient associations and academic social media platforms. The project was approved by the Ethics Committee for Research at the University of Sorocaba (approval number 78747224.7.0000.5500).
