The Impact of Comorbid Conditions on Reading Growth

This session is from the NASP 2021 Annual Convention

  • PMD: 3
  • Skill Level: Introduction
  • Session 4: Assessment and Intervention in an RTI Framework

Learner Objectives

This session will help participants…

  1. learn about shared deficits between reading disabilities and other disorders.
  2. become informed about the prevalence and complications presented by comorbidity.
  3. consider ways to better evaluate, assess, and remediate skills in academic and clinical settings.
  4. understand the current gaps in learning disorder literature specifically concerning comorbidity.


Ninety percent of all specific learning disorders (SLDs) in our schools are in reading. However, struggling readers frequently have comorbid diagnoses such as other SLDs or disorders that are not learning based, which complicates intervention and remediation of skills. This study will examine the impact of comorbidity on reading fluency and comprehension growth across the school year among a reading remediation sample (N = 109; ages 5–12). Future study directions and implications of results will be discussed.
