Abstract

BACKGROUND AND OBJECTIVES: Our study evaluated the necessity of measuring the quality of life (QOL) with physiologic parameters by assessing inter-relationship between self reported measures, which are known as a tool for evaluation of generic and disease specific QOL.
SUBJECTS AND METHOD
From Oct. 2004 to Apr. 2006, polysomnograpy (PSG) results of 127 patients were retrospectively reviewed. QOL was assessed using the Medical Outcome Study 36-Item Short-Form Health Survey (SF-36), Self-reported measures including Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Stanford Sleepiness Scale (SSS), Insomnia Severity Index (ISI), and Beck Depression Inventory (K-BDI). The association between each domain on the SF-36 and self-reported measures were examined by Spearman correlation measures.
RESULTS
ESS, SSS, PSQI and ISI correlated well with SF-36, except for ESS, which didn't with Physical Functioning of SF-36. PSG indexes of patients with OSAS did not show correlation with self-reported measures.
CONCLUSION
All self reported measures including generic and disease specific QOL have their own significance in reflecting psychosomatic status in patients with OSAS. Self-reported measures could be more informative in the reflecting severity and pre/post treatment results in the aspect of psychosomatic effects in OSAS patients.
