Abstract:
OBJECTIVES: We examined the effects of sleep variables and emotional factors including stress, anxiety and depression on the quality of life in insomnia patients. METHODS: We recruited 153 insomnia patients and 96 normal control (NC) subjects who visited three Public Health Centers in Kangwon-do from 2013 until 2015. The Pittsburgh Sleep Quality Index (PSQI), Korean version of Morningness-Eveningness Questionnaire (MEQ-K), Korean version of Epworth Sleepiness Scale, Ford Insomnia Response to Stress Test (FIRST), Hyperarousal Scale (HAS), Perceived Stress Scale (PSS), Anxiety-Sensitivity Index (ASI), Beck Depression Inventory (BDI), and Short Form-12 Health Survey Questionnaire (SF-12) were administered for each subject. We compared the scores of the above scales between the insomnia and control groups, using analysis of covariance to control for age. Stepwise regression analysis assessed the association of these variables with SF-12 scores. RESULTS: The scores of PSQI, FIRST, HAS, ASI, BDI in insomnia patients were significantly higher than those of NC subjects, but the Mental Component Summary (MCS) scores of SF-12 were lower. Stepwise regression analysis showed the scores of PSS and MEQ-K significantly predicted the MCS scores in NC subjects, and the BDI score predicted scores in insomnia patients. CONCLUSION: In our study, greater subjective stress and evening preference could explain lower mental quality of life in NC subjects. In insomnia patients, greater depression is an additional factor.
