뇌졸중 후 실어증 환자의 삶의 질 척도(SAQOL-39): 한국어판의 타당도 및 신뢰도

Abstract

Assessing health-related quality of life(HRQOL) is a matter of primary concern in the medical and social fields these days. The reason is because the evaluation for HRQOL is an useful method for inquiring effects of treatment in a social context. However, the majority of studies regarding HRQOL have excluded aphasic patients or used proxy assessment due to their language problems. Stroke and Aphasia Quality of Life Scale-39(SAQOL-39) is used for measuring quality of life in aphasic patients. In this study, we developed Korean version of the SAQOL-39 (K-SAQOL-39) by translating and cross-culturally adapting its original version and assessed its reliability and validity in Korean aphasic patients. The K-SAQOL-39 had high internal consistency(Cronbach's α=.971) and test-retest reliability(r = .909, p<.001). Verification of the concurrent validity resulted in a high correlation(r = .662, p<.001). Factor analysis findings revealed three distinct conceptual sub-domains that explained 64.11% of the total variance of the data. In conclusion, K-SAQOL-39 is an appropriate for measuring the quality of life for Korean aphasic patients.
