청각장애아동의 의사소통 관련 삶의 질 측정도구 개발

Abstract

This study aims to develop communication-related quality of life scale for children with hearing impairment. It consists of two sections, Study I and Study II. First of all, in order to produce communication-related quality of life scale for children with hearing impairment, in Study Ⅰ, I analyzed precedent research and constructed questions in the stage of question development. And then expert panels verified questions for content validity. Also, they were evaluated for the questionnaire understandability, and thereafter questions were finalized. Then, the Korean sign language based on the questions was produced in the Stuty Ⅰ. This questionnaire examined the item difficulty targeting 151 children with hearing impairment, configuration factors and the questions were abstracted through the explorer factor analysis, and I verified their reliability. As a result of the explorer factor analysis, four factors and twenty-five questions were included in the questionnaire. Also, the constructed validity was verified by the correlation analysis between the scores of four factors and the total score. And as a result of reliability analysis, the reliability in each configuration factor showed a high level of reliability which Cronbach’s α was .78～.86, and each question in the configuration factors showed also a high level of reliability which Cronbach’s α was .71～.86. In Study Ⅱ, I conducted t-test and F-test with diverse background variables, which was based on the collected data and the result of Study Ⅰ. Also, t–test was conducted between the children with hearing impairment and hearing children in the group of the school grades(elementary school, middle school, and high school) by the data collected from 272 hearing children. As a result, first, no difference was found in communication–related quality of life scale for the children with hearing impairment according to gender, school grades, degree of hearing impairment, way of communication practice and whether or not they use auditory assist devices. However, there was significant difference with the time the children with hearing impairment start using auditory assist devices among the groups: the sooner children use auditory assist devices, the better the result comes in communication-related life quality. Second, there was significant difference in communication–related quality of life scale between the hearing children and the children with hearing impairment according to school grades. The children with hearing impairment demonstrated lower score than hearing-children in all configuration factors and total score. Based on the results above, this study discussed the factors of communication–related quality of life scale for the children with hearing impairment, potential background variables of children with hearing impairment and communication-related quality of life of between children with hearing impairment and hearing children. Also, this study suggested the follow-up studies related to this subject.
