Emotional and behavioural problems (EBPs) are receiving increasing attention at the global level, and preschool children are no exception. These issues have a significant impact on future development. Preventive interventions in preschool age are effective in preventing more serious disorders by improving social skills, emotional regulation and resilience in children. Although various preventive interventions have been developed and their effectiveness demonstrated, the evidence remains fragmented. At present, there has been no comprehensive study mapping EBPs prevention interventions at the preschool age level using the Neuman Systems Model approach.

This scoping review will be conducted in accordance with the Joanna Briggs Institute (JBI) methodology for scoping reviews.The completed scoping review will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR). A systematic search will be conducted in four major databases, namely Scopus, PubMed, Web of Science, Cochrane Library, and online searches using Google Scholar, without language and publication year restrictions. Two reviewers will independently screen the literature according to the inclusion criteria and then extract the data. Any differences between the two reviewers will be resolved through discussion with a third reviewer. We will compile, summarise and analyse the extracted data and present the results in figures, tables and descriptive narratives to ensure clarity and facilitate comparison across studies.

Ethical approval is not required, as the review will use only published literature. Findings will be disseminated through publication in a peer-reviewed international journal and may inform policy and practice in early childhood preventive interventions.
