Abstract

OBJECTIVES
Obstructive sleep apnea (OSA) is a disorder characterized by repetitive partial or complete occlusion of the upper airway during sleep that affects quality of life. The aim of this study was to develop the Korean version of the sleep apnea quality of life index (K-SAQLI) and apply it in Korean patients with OSA.
METHODS
Ninety-three patients with OSA completed the K-SAQLI. Its construct validity and responsiveness were tested by comparing the baseline and change scores obtained in each domain (i.e., daily functioning, social interactions, emotional functioning, and symptoms) using the medical outcome survey-short form 36 (SF-36).
RESULTS
The Cronbach alpha coefficients of internal reliability exceeded 0.60 in all the domains (daily functioning, 0.89; social interactions, 0.88; emotional functioning, 0.92; symptoms, 0.67; and total, 0.94). The K-SAQLI had a high test-retest correlation coefficient of 0.73 in the 20 randomized selected patients. The construct validity was confirmed by significant correlations with SF-36 subscale scores.
CONCLUSION
The results of this study demonstrate that the K-SAQLI may be applicable for clinical purposes.
