Abstract

The SF-36 is the most common instrument to check the quality of life for dialysis patients with chronic renal failure. However, there were too much burden for them to answer 36 items of it. So we purposed to develop the RFQoL-K reduced type of the SF-36. Participants who had newly registered for dialysis were enrolled in 29 medical centers during 45months from 2009. We developed the RFQoL-K through 355 people who applied the SF-36 at 3 and 12 months after registration and then checked it's internal validity. External validity about it was checked via 411 people who answered only one time survey after registration. In conclusion, the RFQoL-K had total 14 items which was consisted of 8 items on physical factors and 6 items on mental factors from the SF-36. The RFQoL-K summary scores explained 91-93% of the SF-36 summary scores. The RFQoL-K was well reflected SF-36 because the correlation and the internal consistency between two tools were very high 0.96 to 0.98 and 0.96 to 0.98 respectively.

만성신부전으로 인한 투석환자의 삶의 질 측정도구는 SF-36이 널리 사용되고 있지만 36문항은 설문에 어려운 점이 많아 이를 축소한 RFQoL-K를 개발하고자 하였다. 대상자는 2009년부터 45개월 동안 국내 29개 의료기관에서 만성신부전으로 투석을 시작한 신규등록환자이며 삶의 질 측정은 등록 후 3개월째와 12개월째에 응답한 355명을 대상으로 RFQoL-K를 개발하고 내적타당도를 조사하였으며, 기간 중 한 차례만 응답한 411명을 대상으로 외적타당도를 알아보았다. RFQoL-K는 원도구 36문항 중 신체적요소에서 8개 문항, 정신적요소에서 6개 문항의 14문항으로 축소 하였으며 원 도구를 90~93%설명할 수 있었으며 상관관계도 0.96~0.98로 높았고 내적일치성계수도 0.96~0.98로 매우 높아 RFQoL-K가 원 도구를 잘 반영하였다.
