How to Assess Oral Narrative Skills of Children and Adolescents with Intellectual Disabilities: A Systematic Review.

Children and adolescents with intellectual disabilities (ID) often encounter difficulties with narrative skills. Yet, there is a lack of research focusing on how to assess these skills in this population. This study offers an overview of the tools used for assessing oral narrative skills in children and adolescents with ID, addressing key questions about common assessment tools, their characteristics, and reported evidence. A systematic review was conducted of the literature published between 2010 and 2023 in the PsycINFO, ERIC, Education, and Psychology databases. An initial 1176 studies were reviewed by abstract, of which 485 were read in full text, leading to the selection and analysis of 22 studies. Most of the identified tools involve analyzing language samples obtained using wordless picture story books. Three common tools are emphasized. Studies have primarily identified inter-rater reliability and test-criterion evidence for validity. The main tools and their characteristics are discussed in depth to aid readers in discerning suitable options for research or practical applications. The importance of reporting diverse sources of evidence for validity and reliability within this population is highlighted.
