ABSTRACT

[Purpose] The Parent’s Evaluation of Aural/Oral Performance of Children (PEACH) rating scale is a questionnaire test tool developed to evaluate auditory aural/oral performance of hearing-impaired children with hearing devices in everyday situations. This study aimed to measure the reliability of the Korean version of PEACH in children with cochlear implants (CI) and to investigate the auditory performance and developmental characteristics of children with CI by the implanted age and the hearing age. [Method] Parents of 40 children with CI aged 0 to 7 years who were diagnosed with hearing loss before language acquisition were asked to answer PEACH on a 5-point scale ranging from 0 to 4. To determine the reliability of PEACH, inter-item consistency and test-retest reliability were measured. The PEACH scores (Quiet, Noise, Overall) were obtained for two implanted age groups (implantation before 24 months old [IB], and implantation after 24 months [IA]) and three hearing age groups (0–1, 2–3, and 4–5 years old). The PEACH score differences were compared between items and groups, and the correlation between scores according to implanted age and hearing age was examined. [Results] Cronbach’s alpba values of the Korean version of PEACH were 0.889 in Quiet, 0.825 in Noise, and 0.928 in Overall, indicating high inter-item consistency and significant results in test-retest reliability. No significant difference in scores between the implanted age groups was shown, yet the Quiet scores were significantly higher than the Noise scores in the IB group. Hearing ages 2–3 and 4–5 showed significantly higher scores than 0–1 and significantly higher scores in Quiet than in Noise. The PEACH score increased significantly in the IB group as hearing age increased, but there was no significant correlation in the IA group. [Conclusion] The findings of this study indicate that the Korean version of PEACH is a highly reliable questionnaire, confirming its appropriateness in clinical use. Furthermore, CI users with implantation before 24 months of age showed continuous development, nearly reaching a full score in PEACH at the hearing age of 5–6. Therefore, PEACH could be applied as a useful test tool to provide information on the early-age auditory performance of children with CI.
