Eysenck’s Personality Characteristics Significantly Contribute to the Quality of Life of Colon Cancer Patients

Background: Colon cancer is one of the leading cancers that cause death worldwide. Some studies show that personality characteristics play an important role in coping with colon cancer. This study aimed to explore the association between personality characteristics and quality of life in patients with colon cancer. Methods: A cross-sectional study was conducted on 200 subjects at the Oncology Clinic of the University Clinical Hospital Mostar between April 2019 and June 2021. A socio-demographic survey, the Eysenck Personality Questionnaire, and the WHOQOL-BREF questionnaire (for assessing the quality of life) were used for collecting data. Results: There was a significant positive correlation between extraversion and psychological health, social relations and the environment, and overall quality of life. A statistically significant negative correlation was found between neuroticism and physical health, mental health, and social relationships. Psychoticism correlated negatively with the domains of mental health and the environment. Neuroticism contributed negatively to the level of physical health, mental health, and social relations. Conclusion: Extraversion positively contributes to the quality of life in colon cancer patients. Neuroticism and psychoticism negatively contribute to the quality of life in colon cancer patients.
