The main purposes of this predictive correlational research were to ascertain the relationship between self - care burden and quality of life as well as the ability of self - care burden to predict quality of life among post valvular replacement patients. The purposive sampling technique was used to select 170 post mechanical valvular replacement patients attending the Surgical Heart Clinic at the Out-Patient Department of Maharaj Nakorn Chiang Mai hospital. Zhan's concept of quality of life and Oberst's concept of self - care burden were used to guide the study.

The instruments used to collect the data in this study were composed of personal characteristic data form, the Self - care Burden of Post Valvular Replacement Patient Scale (SB - PVRS) developed by the investigator basing on OberstÕs concept of self - care burden , and the Quality of Life Questionnaire developed by Saifon Jubjai (1997). The Content Validity Index of the self - care burden scale was .87. For the SB - PVRS, the Cronbach's coefficient alpha of the self - care demand domain and self - care difficulty domain were .83 and .91 respectively. The reliability coefficient value of the Quality of Life Questionnaire was .84. The demographic data was analyzed by using descriptive statistic. The simple linear regression was used to test for the relationship between both variables. The results revealed that : 1) There was a negatively significant correlation between self-care burden and quality of life among post valvular replacement patients (r = -.30, p<.001). 2) Self-care burden explained 9% of the variance of quality of life among post valvular replacement patients (R² = .09, p<.001).The finding of the study was discussed in terms of self - care burden and quality of life concepts as presented in the conceptual framework. The implications to clinical nursing practice and further research were recommended.
