Shared Decision Making Interventions for Parents of Children on the Autism Spectrum: A Systematic and Scoping Review

Parents of children on the autism spectrum face challenging treatment-related decisions, often with limited knowledge about available options. Shared Decision Making (SDM), a process where clinicians, patients, and families collaborate to make decisions based on evidence and preferences, can assist parents in navigating these choices. However, little is known about the use of SDM interventions for autism-related parental decisions. A systematic and scoping review was conducted across four databases (PubMed, Embase, Web of Science, and PsycInfo), and grey literature in two clinical trial registries. Study selection was conducted in two phases: title and abstract screening and full-text screening. From 7,610 records identified, two studies were included from Australia and Italy, describing multicomponent SDM interventions for parents of young children (< 18 years) on the autism spectrum. Both interventions demonstrated improvements in SDM-related outcomes, including parents' knowledge of autism treatments (such as speech pathology services and Early Intensive Behavior Intervention) and parents' involvement in treatment discussions. This review reveals a critical gap in SDM intervention research for autism parental decision-making. Despite the critical role parents play in autism treatment decisions, evidence-based SDM interventions remain scarce. This finding is significant given the well-established benefits of SDM in other healthcare populations and underscores the urgent need to develop and rigorously evaluate SDM interventions tailored to autism care contexts that support parents in making informed decisions about their children's care.Systematic review registration: A protocol was registered on PROSPERO.
