Background and ObjectivesZZTo improve hearing screening, we developed a more effective hearing screening questionnaire for infants and children to be utilized during medical check-ups. Subjects and MethodZZThrough literature review and discussions with an advisory council, we selected 10 questions to ask parents at each of the seven screening periods for their infants and children. In total, 223 parents of infants and children with and without hearing impairment (119 normal hearing, 104 hearing impaired) answered questionnaires at seven university hospitals in Korea. The advisory council modified questions with regard to sensitivity, specificity, positive, and negative prediction rate, preventing duplication among screening periods, and to address other questions related to development. ResultsZZFor hearing screens, we asked five questions per screening period. Collectively, these questions had 40-100% sensitivity and 45-90% specificity at each of the seven screening periods. ConclusionZZAlthough we do not advise that hearing questionnaires replace hearing tests, we developed in this study a more effective questionnaire that we suggest could be utilized during medical check-ups to enhance the hearing screening process.
