ABSTRACT
OBJECTIVE@#To develop and evaluate the improved Chinese hearing questionnaire for school children (CHQS) for mass epidemiology study on hearing impairment in China.@*METHOD@#Using the probability proportion to size (PPS) method, 8412 residents were investigated in 40 clusters in Jiangsu province with the WHO ear diseases and hearing disorders survey protocol. 87.9% of the residents aged 7 years and over answered the questionnaire and accepted the pure tone audiometry.@*RESULT@#The prevalence of hearing impairment was 12.9% by the questionnaire. Compared with "golden standard" (pure tone audiometry), Sen = 58.5%, Spe = 96.7%, PV+ = 78.9%, PV- = 91.7%, overall accuracy = 90.0%. The sensitivity for women was higher than men.@*CONCLUSION@#The questionnaire produced high efficiency and specificity values. It could be used in mass hearing screening, particularly in remote and rural area, although the sensitivity was as low as most questionnaires.
