The Functional Communication Classification System: extended reliability and concurrent validity for children with...

Area of Science:

• Pediatric rehabilitation
• Communication sciences
• Developmental disabilities

Background:

• Children with cerebral palsy (CP) often experience communication impairments.
• Accurate classification of communication function is crucial for effective intervention and research.

Purpose of the Study:

• To evaluate the psychometric properties and clinical utility of the Functional Communication Classification System (FCCS).
• To assess FCCS for classifying communication function in children with CP aged 5-18 years.

Main Methods:

• Eighty-two children with CP (ages 5-17) were rated using FCCS by speech-language pathologists (SLPs) and parents.
• FCCS ratings were compared with measures of everyday communication, motor function, and associated impairments.
• Interrater agreement (kappa statistics) and correlations (Spearman's) were analyzed.

Main Results:

• Almost perfect interrater agreement was found between SLP and parent FCCS ratings (κw = 0.96).
• FCCS showed excellent correlations with pragmatics, motor speech, and intellect.
• Moderate correlations were observed with gross/fine motor function, and fair correlations with epilepsy, hearing, and vision.

Conclusions:

• The FCCS is a reliable and valid tool for classifying communication in children with CP.
• Its strong psychometric properties support its use in surveillance, research, and clinical practice.
• FCCS demonstrates high suitability for diverse applications in pediatric communication assessment.
