Area of Science:

• Pediatric Rehabilitation
• Neurology
• Speech-Language Pathology

Background:

• The Eating and Drinking Ability Classification System (EDACS) lacks extensive evidence for its concurrent validity.
• Accurate assessment of eating and drinking abilities is crucial for children with cerebral palsy (CP).

Purpose of the Study:

• To determine the concurrent validity and reliability of the Eating and Drinking Ability Classification System (EDACS) in children and adolescents with cerebral palsy (CP).

Main Methods:

• The German version of EDACS was applied to 52 participants with CP.
• Correlations were calculated between EDACS levels and the Bogenhausener Dysphagiescore (BODS), Manual Ability Classification System (MACS), and the WeeFIM eating item.
• Interrater reliability was assessed between speech and language therapists (SaLTs) and between SaLTs and parents using Kappa statistics.

Main Results:

• EDACS levels showed high correlation with BODS (Kτ=0.79).
• EDACS level of assistance correlated highly with MACS (Kτ=0.73) and WeeFIM eating item (Kτ=-0.80).
• Interrater reliability was almost perfect between SaLTs (EDACS: κ=0.94) and between SaLTs and parents (EDACS: κ=0.82).

Conclusions:

• The EDACS demonstrates concurrent validity and high interrater reliability for classifying eating and drinking problems in children and adolescents with CP.
• The German version of EDACS is a reliable tool for clinical use in this population.
