Correlation Analysis between Self-reported Measures in Patients with OSA / 대한이비인후과학회지

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.
