Preliminary Validation of the Children's Auditory Performance Scale (CHAPS) and the Auditory Processing Domain...

Identification of auditory processing disorders is achieved using questionnaires along with linguistic, non-linguistic, and auditory processing tests. Notably, the questionnaires "Children's Auditory Performance Scale" (CHAPS) and "Auditory Processing Domain Questionnaire" (APDQ) are widely recognized and used. The current study investigated the psychometric properties of the CHAPS and APDQ in Greek Cypriot children.

The CHAPS and APDQ questionnaires were completed by parents of 40 Greek Cypriot children, 16 typically developing (TD) children, and 24 children with a history of Speech Sound Disorders (SSDs).

There were significant differences between the two groups on both questionnaires. Cronbach's alpha was calculated at α = 0.922 for the CHAPS total score and α = 0.926 for the APDQ total score. The Receiver Operating Curve (ROC) analysis provided a cut-off point equal to -0.30 (AUC 0.849, p < 0.001) for CHAPS and a cut-off point equal to 90.00 (AUC 0.820, p < 0.001) for APDQ. Significant positive Spearman ρ correlations were observed between the CHAPS and APDQ (ρ = 0.639, p = 0.001).

The CHAPS and APDQ can identify distinct auditory processing characteristics between in children with SSDs and TD children.
