Purpose: The purpose of this study was to investigate the influencing factors on health-related quality of life of physically disabled persons. Method: Data was collected from 96 persons with a physical disability in three cities in Korea from June to September, 2003. Social support and depression were measured by a Social Support Questionnaire 6 ($SSQ_6$) and Center for Epidemiologic Studies Depression questionnaire (CES-D). The Rosenberg Self-esteem Scale was used to measure self-esteem. Health-related quality of life (HRQOL) was measured using Smith Kline Beecham Quality of Life Scale (SBQOL). The SPSS WIN 11.0 version program was used for data analysis. Result: There were significant differences of HRQOL according to monthly income and economic status. All subjects had a high level of depression and low self-esteem. Conclusion: The findings of this study show that self-esteem and the size of the social support network are significant influencing variables on HRQOL in physically disabled persons. Nursing intervention and counseling programs which improve self-esteem and increase the size of a social support network are needed to promote HRQOL in physically disabled persons.
