Identifying major research themes in the literature on developmental disabilities in Middle Eastern countries: A scientometric review from 1962 to 2023

Developmental disabilities have been widely studied in higher-income countries. However, most individuals with these conditions live in low-and middle-income countries and they are reportedly under-represented in the scientific literature. To tackle this issue, previous research has provided insight into the thematic developments in the research on developmental disabilities in Africa by means of a scientometric approach to reviews. The current work aims to extend the scientometric approach to investigate the main interests in the literature on developmental dis-abilities conducted in Middle Eastern countries. A total of 1110 documents were retrieved from Scopus and their patterns of co-citation were analysed with the CiteSpace software. Research in Developmental Disabilities emerged to be the main source in the sample of downloaded documents. Furthermore, a total of six main thematic domains and the four most impactful documents in the literature were identified. Results showed that research on developmental disabilities in the Middle East has been mainly focused on uncovering the genetic basis of this group of conditions. The study of clinical profiles, diagnosis, management, and treatment of individuals with devel-opmental disabilities have been so far under-investigated and represents material for future studies.
