Abstract

Purpose: The purpose of this study was to explore influence of Type D personality of hemodialysis patients on quality of life and to elucidate mediation effects of depression and social supports between Type D personality and quality of life.

Methods: The subjects were 126 patients who were receiving hemodialysis treatments at four dialysis clinics in Pusan and Daegu metropolitans. Data were collected from January 22th to February 28th, 2018 and analyzed with descriptive statistics, χ2 test, independent t-test, Pearson's correlation coefficient and three-step mediated regression analysis using SPSS/WIN 22.0. Significances of mediation effects were examined using bootstrapping method based on SPSS Process Macro program.

Results: The prevalence of Type D personality in hemodialysis patients were 42.9%. Type D personality in hemodialysis patients had significant effects on quality of life, showing explanatory power of 12%. Depression showed complete mediating effects and also showed 42% of substantiating probability, and social supports showed partial mediating effects and showed 19% of substantiating probability.

Conclusion: Summing up the result of research until now, in order to improve the quality of life for Type D personality hemodialysis patient, it is necessary to develop strategies not only to relieve depression using early evaluation on depression status, consulting therapy, cognition behavior mediation and so on, but also to enhance social supports like participating in voluntary meetings and building up social network to expand relationship with close people.
