MetadataShow full item record
Objective: This study was to establish Chinese norms of Parent’s Evaluation of Aural/Oral of Children (PEACH) rating scale, and to investigate the test-retest reliability and validity for this adapted version. Design: The PEACH scores were collected from parents whose children have normal hearing. The test-retest reliability of the PEACH scale was evaluated in a subgroup of parents. Correlation analysis was used to explore the relationship between the PEACH ratings and language scores. Study sample: A total of 198 parents participated in the present study, of whom 34 parents completed the questionnaire twice within 1-3 weeks, and another 27 parents also filled out a language questionnaire. Results: The normative curve of the total score was established using a logit regression function. The test-retest analyses showed high reliability for all subscales, with all the correlation coefficients values exceeding 0.9 (p<0.01). The 90% and 95% confidence intervals were provided to facilitate evaluation of differences between scores obtained under different conditions. A significant correlation was found between the PEACH total score and language expressive outcome (p < 0.05). Conclusions: Normative data from the Chinese population was provided to enable performance of an individual child to be related to their normally hearing peers.
