The Purpose of the this study was to identify reliability and validity of the Korean version of the Swallowing Quality of Life questionnaire(KSWAL-QOL). The study was performed in 71 patients diagnosed dysphagia by videofluoroscopy and 80 healthy swallowers. The reliability was good with a Cronbach's ${\alpha}$ and intraclass correlation coefficient of .86~.96 and .80~.93, respectively. The Pearson product moment correlation coefficients between KSWAL-QOL scales ranged from .17~.74 which was showed significant correlation. Healty swallowers scored higher than dysphagic patients on all scales and statistically significant differences were observed across all the scales between healthy swallowers and dysphagic patients(p<.01). Tube feeders scored lower than non-tube feeders on all scales and statistically significant differences were observed in all the scales except sleep(p<.05). There are significant difference between diet steps in all scales except eating desire, communication, fear and people on diet fourth step feeding had the highest scores on the all scales(p<.05). Because KSWAL-QOL seems to be a reliable and valid tool, it is considered to be appropriate as a tool to measure quality of life of patient with swallowing disorder.
