Narrative Language and Reading Comprehension in Students With Mild Intellectual Disabilities.

This was an observational study of associations after a reading intervention, not a comparison of treatment effects, so it cannot show that improving narrative skills causes better reading comprehension. The sample had heterogeneous causes of intellectual disability, including Down syndrome, fragile X syndrome and unspecified conditions, so results may not apply equally to each group. IQ scores were available for only 82 of 102 students, so the intellectual profile of the full sample is incomplete. Narrative microstructure was measured with broad language-length and vocabulary counts, not detailed grammar features such as past tense or agreement. The narrative task used a single wordless picture book and an adapted scoring scheme, so performance may not generalise to other stories or settings. Participants were students in the southeastern United States who spoke English as a first language and met school-identified eligibility criteria, which may limit generalisability.

The paper does not include a conflict-of-interest statement; the listed publication types indicate NIH and U.S. government support.

Do not read the link between narrative ability and reading comprehension as proof that teaching narrative improves reading. The study measured associations after a reading intervention, not the effect of an intervention, so it cannot show that story-level language caused better comprehension.
