RESUMO
INTRODUCTION: Malignant diseases are one of the leading mortalities in the world, causing a range of psychological symptoms and reducing the quality of life in oncology patients. Examine the correlation of religion with the quality of life and psychological symptoms in oncology patients. SUBJECTS AND METHODS: The cross-sectional study included 100 oncology patients in the test group and 80 internal medicine patients in the control group. A sociodemographic questionnaire was specifically designed for this study, the Duke University Religion Index, the Symptom Check List 90, and the WHOQOL-100 quality of life assessment were used to collect the data. RESULTS: The average score in oncology patients was significantly lower on the subscales for physical health (p<0.000), social connections (p<0.002), and intrinsic religiousness (p<0.046) in comparison to internal medicine patients. On the psychological symptoms scale, the average score was higher in oncology patients with the largest difference observed on the psychoticism subscale (p<0.078). CONCLUSION: Oncology patients are statistically less religious and are not satisfied with the quality of life in comparison to internal medicine patients. Psychological symptoms are more pronounced in oncology patients but the difference is not statistically significant. A lower level of religiousness is statistically negatively correlated with a higher severity of psychological symptoms.
