ABSTRACT

Purpose:
This study was to develop the quality of life (QOL) scale for adult and elder with hearing loss.
Method:
500 hearing impaired who were over 50’s participated. Firstly, 52 preliminary question items selected out of 100 key words were analyzed with average, standard deviation, skewness, kurtosis, correlation coefficient and variance inflation factor. Secondly, exploratory factor analysis was conducted. Prior to this analysis, Kaiser-Meyer-Olkin (KMO) and sphericity of Barlett were confirmed to validate the suitability of the process. Finally, confirmatory factor analysis was conducted with convergent and discriminant validities. To verify fitness measurement of the factor model, Turker-Lewis index (TLI), root mean error of approximation (RMSEA), comparative fit index (CFI) were also measured.
Results:
The values of average, standard deviation, skewness, kurtosis, correlation coefficient and variance inflation factor were within a permitted limit of discrimination and normality of 52 preliminary question items. The KMO value was 0.930 and Barlett value was 8886.460 (p < 0.001). Through exploratory factor analysis, final five factors and 31 items were extracted. This final items were named as quality of life in adult and elder with hearing loss (QOL-AEHL). Confirmatory factor analysis confirmed the high internal consistency showing over 0.7 at construction reliability for all five final factors. The value of TLI, CFI, RMSEA were 0.862, 0.874, and 0.063 verifying suitability of fitness measurement of the factor model.
Conclusion:
QOL-AEHL can be a useful tool to enhance the quality of life for the hearing impaired. Further study should be performed for standardization for practical application.
