PURPOSE: Children with ADHD are at elevated risk for language impairment (LI). This study examined the feasibility of using the Children's Communication Checklist-2 (CCC-2; Bishop, 2006) to classify risk for LI in young children, ages 5 to 8 years, with ADHD.
METHOD: Parents of 32 children with ADHD and 12 typical peers completed the CCC-2. The Clinical Evaluation of Language Fundamentals-4 (CELF-4) and the Test of Narrative Language (TNL) were administered to diagnose LI. Language samples were collected to examine clinical markers of LI.
RESULTS: CCC-2 General Communication Composite scores ≤ 85 correctly classified ten participants with ADHD diagnosed with LI as defined by composite scores ≤ 85 on the CELF-4 or TNL. Five of these participants demonstrated one or more clinical markers of LI in language samples. Three additional participants, who received a GCC score ≤ 85, yet scored above 85 on language tests, demonstrated CCC-2 profiles suggestive of pragmatic impairment. Sensitivity and specificity rates were 100% and 85.29% respectively. CCC-2 scores and most measures were significantly correlated.
CONCLUSION: The results support the feasibility of using the CCC-2 as a screener to identify children with ADHD who are at elevated risk for LI and need referral for comprehensive assessment.
