This study aimed to examine the quality of life (QOL) and well-being of haemodialysis patients and the relationship of two components of perceived expressed emotion (criticism/hostility and emotional over-involvement) and other psychosocial resources within the Conservation of Resources Model. Demographic variables and haemodialysis related information of patients, classified as resources, were also included in the study. One hundred and six haemodialysis patients voluntarily participated in the study. Before the main study, for evaluating the psychometric properties of the Symptom Distress Scale (SDS), Coping Self-Efficacy Scale (CSES), and Perceived Expressed Emotion Scale (PEES) a pilot study was conducted with the fifty-three haemodialysis patients. Results of the pilot study provided support for the reliability and validity of scales. For the main study, optimism, self-esteem, and perceived social support were taken as resources and were also included as measures. In order to test the main hypothesis of the studies a series of regression analyses were conducted. The results of the analysis revealed that predictors of well-being were age, self esteem, criticism/hostility factor of perceived expressed emotion and coping self-efficacy; predictors of physical health component of QOL were age, education, presence of additional diagnosis, and coping self-efficacy. Moreover, it was found that predictors of mental health component of QOL were the presence of additional diagnosis and coping self-efficacy; and predictors of the mean score of QOL were age, presence of additional diagnosis, self-esteem, and coping self-efficacy. Directions of the relationship between age, education, presence of additional diagnosis, and criticism/hostility were negative with the outcome variables, whereas, directions of the relationship between self-esteem and coping self-efficacy were positive with the outcome variables. The mediational role of coping self-efficacy in the association between resources and outcome variables were also investigated. Mediator effect of coping self-efficacy was found only for two variables. Firstly, the effect of duration of haemodialysis treatment was mediated by the coping self-efficacy for the well being measure. Second, coping self-efficacy carries the influence of the family income to the mean score of QOL. After discussing the findings of the present study in the light of the literature, the limitations and the clinical implications of the results and directions for the future studies were suggested.
