Global research trends on sensory processing in children with autism spectrum disorder: A bibliometric analysis supporting sustainable child health

Abstract

Sensory processing is a key characteristic of children with Autism Spectrum Disorder (ASD), affecting adaptive functioning, participation, and quality of life. Despite the growing number of publications, a comprehensive overview of global research trends remains limited. This bibliometric study analysed global research on sensory processing in children with ASD to identify publication characteristics, knowledge structure, emerging themes, and future research directions. Data were retrieved from the Scopus database. A total of 1,552 publications (1980-2026) were analysed using Scopus and VOSviewer version 1.6.21 analytical tools. Publications increased markedly after 2017 and reflect a multidisciplinary approach. Network analysis identified six interconnected knowledge domains, with ASD and sensory processing as the core concepts linking neurobiology, clinical characteristics, neurodevelopmental disorders, assessment, intervention, and functional participation. Emerging themes included mental health, neurodiversity, ADHD, food selectivity, and neurodevelopmental disorders, indicating a shift toward holistic, quality-of-life-oriented research. These findings provide a scientific basis for future research priorities and the development of multidisciplinary, sustainable child health services.
