People that are diagnosed with cancer respond to the illness and medical care in their own way. Patient’s illness perception may have an effect on the mental health and on how they deal with medical conditions. Knowledge on illness perception and quality of life (QOL) can help the cancer patients to cope more effectively. In developing countries, there is very limited information about perception of cancer patients towards their condition. The aim of this study is to identify the association between illness perception and health related quality of life in Indonesian cancer patients.
This study is a cross sectional study that took place in Siloam General Teaching Hospital located in a suburban area of Tangerang. This study took place from July 2016 to January 2017. The samples included in this study were adult solid cancer patients. Health related QOL was measured using EORTC QLQ-C30. Illness perception was measured using Brief Illness Perception Questionnaire (B-IPQ). Analysis was done using Pearson or Spearman correlation.
From total 56 patients, 50 (89.3%) were female. The mean age of the patients was 48.6 (±10.9) years. Breast cancer was the most common type of cancer (76.7%), followed by adenocarcinoma of the colon (8.9%). The emotional representation subscale has significant correlation with global health status (r = -0.268; p = 0.046), cognitive functioning (r = -0.288; p = 0.031) and social functioning (r = -0.268; p = 0.045) domains of QOL. The identity domain has significant correlation with dyspnea (r = 0.297; p = 0.026) and diarrhea (r = 0.297; p = 0.026). The other subscales of illness perception did not have significant association with QOL.
Several subscales of illness perception had significant association with health related QOL. The knowledge about the relation between illness perception and QOL will allow the development of strategies in order to improve the global health status and functioning of solid cancer patients in our centre.
