Investigating Reading Comprehension in Adolescents with Intellectual Disabilities: Evaluating the Simple View of...

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Special Education

Background:

• Reading comprehension difficulties are prevalent in individuals with intellectual disabilities (ID).
• Underlying cognitive and linguistic predictors of reading comprehension in ID populations are under-researched.
• Investigating developmental patterns (delayed vs. different) is crucial for understanding these difficulties.

Purpose of the Study:

• To test the Simple View of Reading framework for adolescents with non-specific ID.
• To identify cognitive and linguistic predictors of reading comprehension in this group.
• To determine if the developmental pattern of predictors is delayed or different.

Main Methods:

• Structural equation modeling was used to analyze data from 136 adolescents with non-specific ID.
• Participants were assessed on reading comprehension, decoding, linguistic abilities, and cognitive functions.
• The study examined predictors of both listening and reading comprehension.

Main Results:

• The Simple View of Reading did not adequately explain reading comprehension in adolescents with ID.
• Vocabulary and phonological executive-loaded working memory were identified as concurrent predictors of comprehension.
• These predictors indicated a delayed developmental profile rather than a different one.

Conclusions:

• The Simple View of Reading is not universally applicable to individuals with intellectual disabilities.
• Cognitive and linguistic abilities, specifically vocabulary and working memory, follow a delayed developmental trajectory in this population.
• Understanding this delayed profile is essential for targeted reading interventions for adolescents with ID.
