Examining the Word Level Skill and Reading Comprehension Profiles of Adolescents with and without Specific Learning...

Area of Science:

• Educational Psychology
• Developmental Psychology
• Neuroscience

Background:

• Literacy development in adolescents is complex and varies significantly.
• Specific Learning Disability (SLD) often impacts reading skills, but profiles of difficulty are not fully understood.
• Understanding these profiles is key for targeted educational interventions.

Purpose of the Study:

• To identify distinct literacy profiles among adolescents with and without SLD.
• To examine the stability and change of these profiles from 6th to 8th grade.
• To determine if literacy profiles predict later reading comprehension.

Main Methods:

• Latent profile analysis (LPA) to identify subgroups based on word-level skills and reading comprehension.
• Latent transition analysis (LTA) to track changes in profiles over time (Grades 6-8).
• Regression analysis to predict end-of-year reading comprehension from identified profiles.

Main Results:

• Most adolescents performed below average in word-level skills or comprehension; word-level deficits were more common.
• Students with SLD showed consistent literacy profiles over time, while typically developing students showed more variability.
• Literacy profiles had limited predictive power for broad reading comprehension at year-end.

Conclusions:

• Adolescents often exhibit co-occurring word-level and reading comprehension difficulties.
• Sustained, targeted intervention in word-level skills is essential for adolescents with concurrent reading challenges.
• Educational strategies should address the heterogeneity of literacy profiles for effective support.
