Han, Kim, and Yoon: Factors Influencing Functional Health of Patients with Chronic Insomnia based on Theory of Unpleasant Symptoms

Abstract

Purpose

The purpose of this study was to identify factors influencing functional health of patients with chronic insomnia based on the Theory of Unpleasant Symptoms (TOUS).

Methods

Data were collected from 184 patients with chronic insomnia who had been treated at the sleep center in hospital in South Korea. Data were collected from 23 December 2014 to 18 May 2015 through self-reported questionnaires from pre-sleep arousal, worry, perceived stress, social support, insomnia symptom, and functional health. Data were analyzes using an independent t-test, one-way ANOVA, Pearson's correlation coefficient, and hierarchical multiple regression analysis with the SPSS/WIN 21.0 program.

Results

The regression model had an adjusted R2 of 50%, which indicated that pre-sleep arousal, social support, perceived stress, education, and insomnia symptom were significant predictors of functional health in patients with insomnia.

Conclusion

In order to improve the functional health of patient's with chronic insomnia, clinical nurses should develop and provide nursing interventions that improve social support and reduce pre-sleep arousal, stress, and insomnia symptoms.
