Abstract

In cancer patients, improving the quality of life is a basic goal of treatment, with the patient – physician relationship as a major factor. Therefore the aim of this structural equation modeling study was to analyze the influence of patient involvement in care on quality of life in 411 breast cancer patients undergoing outpatient chemotherapy and radiotherapy. Two questionnaires were used: 1-patient-physician questionnaire, 2-EORTC QLQC-30 (to measure QOL). The structural equation model exhibited an excellent data fit (Chi-Square= 31.04 / RMSEA= 0.042), T-values for all paths with the exception of that between patient satisfaction and emotional- cognitive function, were significant. According to the findings, various aspects of the physician-patient relationship are significantly and positively associated with quality of life and increasing patient involvement in care by increasing trust and satisfaction, was associated with marked improvement. The findings of this study emphasized the importance of an effective relationship between doctor and patient as a contributing factor for improving the quality of life. Therefore it is suggested that policymakers and decision-makers active in strategic planning for the health system and physicians responsible for treatment pay more attention to developing and improving relationships with patients as an approach to improving patient outcomes, particularly with reference to quality of life.
