Reading comprehension intervention in populations with developmental language disorder: A scoping review.

Joseph Hin Yan Lam, Jiali Wang, Amy S Pratt and 1 others

PMID 41401742

WHAT IT FOUND

Interventions targeting vocabulary and morphology showed consistent gains, while decoding and discourse results varied.

Most studies were small, short, and lacked blinding, so no single approach is proven superior for improving reading comprehension in children with developmental language disorder.

Key findings

01All interventions targeting vocabulary knowledge and morphological awareness reported significant positive gains in reading comprehension.

02Results for interventions targeting word recognition (decoding) were mixed, with some showing no significant difference in reading comprehension between groups or pre- and post-tests.

03Extended discourse interventions showed limited findings, with some studies reporting no significant difference in reading comprehension compared to controls.

What it does not show

The review is a scoping review, not a systematic review or meta-analysis, so it maps the field rather than quantifying effect sizes or definitively ranking interventions. Included studies had highly variable dosages, intensities, and durations, making it difficult to determine the optimal amount of intervention needed. Most studies involved young children (learning-to-read stage) and monolingual English speakers, limiting generalizability to adolescents or multilingual children with DLD. Risk of bias was present in many studies, including a lack of blinded assessment and few studies reporting power analyses. Standardized outcome measures may not fully capture nuanced reading comprehension changes in children with DLD.

Declared interests

The authors declare no conflicts of interest.

The easy way to misread this

Do not interpret the consistent gains in vocabulary and morphology interventions as proof that these are the only or best approaches for all children with DLD. The evidence base is heterogeneous, with many small, unblinded studies and varying dosages, so no single intervention type is definitively proven superior for reading comprehension outcomes.
