Total Pain and Fear of Recurrence in Post-Treatment Cancer Patients: Serial Mediation of Psychological Flexibility and Mentalization and Gender Moderation

: The research indicates that painful experiences can significantly affect the fear of cancer recurrence among cancer survivors, which is a distressing concern that influences both physiological and psychological recovery. This cross-sectional study aims to advance our comprehension of the associations between total pain and the fear of recurrence in post-treatment cancer patients by examining two potential mediators: psychological flexibility and mentalization. Three hundred and thirty-five participants (aged 22 to 88, 49.1% female) who had finished their cancer treatment completed self-report assessments of total pain, their fear of recurrence, psychological flexibility, and mentalization. The serial mediation analysis showed that all dimensions of total pain were positively and indirectly related to the fear of recurrence through psychological flexibility and mentalization in serial. Additionally, gender was found to moderate these serial mediational effects. In line with the psychological flexibility model, personal capacities to face difficult internal/external problems and interpret one's behavior in motivational terms can counterbalance a patient's negative emotions and feelings related to the illness. Gender factors also determine the way in which post-treatment cancer patients manage potential future anxiety and fears.
