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, 8 412 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.
