Objective: To explore the mediating effect of coping style between illness perception and fear of cancer recurrence in patients undergoing radical prostatectomy.
Methods: A questionnaire survey was carried out in 254 eligible patients who underwent radical prostatectomy in the urology department of two comprehensive tertiary hospitals in Wenzhou City from June 2022 to December 2022. The questionnaires include the general data questionnaire, brief illness perception questionnaire (BIPQ), Medical Coping Modes Questionnaire (MCMQ) and Fear of Progression Questionnaire-Short Form (FoP-Q-SF). A structural equation model was used to analyze the mediating effect of coping style between illness perception and fear of cancer recurrence.
Results: The score of fear of cancer recurrence in prostate cancer patients is (30.08 ± 10.11). Illness perception, avoidance, and surrender coping styles could forward prediction fear of cancer recurrence (P=0.001, P=0.019, P=0.001); facing coping styles can negatively predict fear of cancer recurrence (P=0.001). Coping style played a part of the mediating role between illness perception and fear of cancer recurrence, and the mediating effect is 0.150，which accounted for 47.62% of the total effect.
Conclusion: Coping style is a mediator between illness perception and fear of cancer recurrence in patients undergoing radical prostatectomy. Doctors and nurses should reduce patients' negative perception, guide them to adopt positive coping strategies, and thereby reduce their fear of cancer recurrence.
