摘要

Effective auditory processing is crucial for academic success in school-aged children. Auditory Processing Disorder (APD), which involves deficits in processing auditory information despite normal hearing, can impact key skills such as understanding speech in noise. Due to varying prevalence rates reported across studies, more research is needed to clarify APD’s prevalence across diverse populations. This study aims to estimate the prevalence of APD among 9–12-year-old children in Shiraz, Iran, and to highlight the importance of early detection and intervention for APD cases. This cross-sectional study involved 240 students (140 boys and 100 girls) aged 9–12 years. Parents completed the Persian version of the Buffalo Model Questionnaire (BMQ), and candidates who screened positive underwent further diagnostic evaluation for APD using the Dichotic Digit Test (DDT), Pitch Pattern Sequence Test, and Monaural Selective Auditory Attention Test. Based on questionnaire responses, ten children underwent diagnostic testing, all of whom met the criteria for APD, yielding an overall prevalence rate of 4.16%. No significant gender differences were observed. Age-stratified analysis revealed a trend suggesting a linear increase in prevalence with age. The DDT exhibited the highest rate of abnormalities, whereas deficits in pitch pattern recognition were less common. The findings indicate that the BMQ, together with the employed diagnostic tests, provide a reliable approach for identifying APD in school-aged children. Prioritizing early detection is essential for enhancing intervention outcomes and minimizing long-term academic challenges. The implementation of standardized assessment protocols and routine school-based auditory screenings is strongly recommended.
