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.

PURPOSE
The aim of this study was to examine patients with Chronic Hepatitis B (CHB) and their level of knowledge of their disease, uncertainty, stress and health behaviors and to identify factors influencing their health behavior.
METHODS
A cross-sectional, descriptive design was used. The sample included 136 patients in a gastroenterology outpatient department at one hospital located in Seoul. The mean age of the subjects was 41 and 77.2% were male. Data were collected using a structured questionnaire from April to June 2009. The collected data were analyzed using SPSS/WIN 15.0.
RESULTS
The reported scores for knowledge of the disease, uncertainty, stress, and health behaviors were 14.43, 81.50, 26.50, 52.11, respectively. There were statistically difference between health behaviors and gender, age, marital status and antivirus treatment. A positive correlation existed between knowledge of disease and health behaviors (r=.199, p=.020). In contrast, there was a negative correlation between uncertainty and health behaviors (r=-.250, p=.003). The factors influencing health behaviors were knowledge of disease, gender, age, uncertainty, antivirus treatment, and marital status (R2=.267, p<.001).
CONCLUSION
These findings support that strategies for enhancing knowledge of disease and reducing uncertainty are needed to promote health behavior in patients with CHB.
