ABSTRACT

Objective: This study intends to understand the impact of the quality of sleep and level of depression of stroke patients on their quality of life. Methods: A survey was conducted with 155 stroke patients hospitalized or visiting as outpatients in the rehabilitation hospitals located in Daejeon. General characteristics were identified through percentage and frequency analysis, and the average scores for the quality of sleep, depression level, and quality of life were confirmed through descriptive statistics and one-way analysis of variance. The respondents were classified into depressed and non-depressed groups and sleep disorder group and non-sleep disorder groups, and an independent t-test was conducted. The correlation of unobserved variables with quality of life was analyzed, and the causality of factors influencing quality of life was analyzed through regression analysis. Results: Causality among the quality of sleep, level of depression, and quality of life was confirmed, and, as a result of hierarchical multiple regression analysis to confirm the causality between variables, a significant explanatory power was shown between gender and patterns-of-care (R ²=.15) in Model 1; patterns-of-care and level of depression (R ²=.33) in Model 2; and gender, level of depression, loss of sleep, and quality of sleep (R ²=.37) in Model 3. Conclusion: Correlation and causality among factors was confirmed by surveying and analyzing the quality of sleep, level of depression, and quality of life of stroke patients, and the future direction for occupational therapy for the improvement of quality of life could be understood.
