Fear of recurrence of cancer is one of the most important psychological issues in the post-treatment period, which is considered in the framework of psycho-oncology as a multidimensional experience influenced by cognitive, emotional, and social factors. This fear can be accompanied by constant concern about the recurrence of the disease, sensitivity to physical symptoms, anxiety during medical follow-ups, and impaired quality of life. Investigating the structural model of fear of recurrence based on resilience, social support, and health anxiety can help to identify direct and indirect relationships between protective factors and psychological vulnerabilities.
Resilience is an important variable in adaptation to the cancer experience and refers to a person's capacity to maintain or restore psychological functioning in the face of stress and difficult situations. Survivors with higher resilience are usually more able to manage negative emotions, adapt to uncertainty, and use adaptive coping strategies. In the structural model, resilience can be expected to be associated with fear of relapse by reducing vulnerability to anxiety and strengthening a sense of psychological control. However, resilience does not imply immunity to fear, and even people with appropriate psychological resources may experience fear of relapse in certain situations, such as when conducting follow-up tests.
Social support is also an important environmental factor in post-cancer adjustment. Emotional support from family, friends, and the social network can increase feelings of belonging, security, and access to coping resources, and reduce the severity of psychological isolation. Appropriate social support may be directly related to reducing fear of relapse, as well as having an indirect effect by strengthening resilience or reducing health anxiety. In contrast, a lack of support or experience of inappropriate social relationships can increase feelings of vulnerability and make it more difficult to cope with the uncertainty of the disease.
Health anxiety is particularly important in this model as one of the variables of psychological vulnerability. A person who is hypersensitive to his or her physical condition may interpret normal changes in the body as threatening and associate them with the possibility of relapse. In such a situation, constant body monitoring, seeking medical information, and seeking reassurance can strengthen the cycle of anxiety. Therefore, it can be expected that health anxiety has a positive and direct relationship with the fear of relapse; the more concerned about the patient's physical condition, the more likely he is to be mentally occupied with the recurrence of the disease.
From a structural point of view, the relationships between these variables can be considered in the form of a multi-pronged model, so that resilience and social support are considered as protective resources and health anxiety as a vulnerability factor. In this model, resilience can be directly related to the fear of relapse and at the same time affect it by reducing health anxiety. In addition to the direct effect, social support can also play an indirect role in reducing the fear of relapse by strengthening resilience and reducing the feeling of psychological insecurity. Such a model allows the simultaneous study of direct, indirect, and interactive pathways between psychological and social variables.
Research evidence in psycho-oncology suggests that protective factors such as resilience and social support are associated with better post-cancer adjustment and higher quality of life, while variables such as health anxiety and extreme worry about physical symptoms are associated with psychological distress and greater fear of recurrence. However, the intensity and direction of these relationships may vary based on the type of cancer, stage of the disease, duration of treatment, physical condition, age, history of psychological problems, and quality of social relationships. Therefore, the structural model should be interpreted based on the characteristics of the study community and the clinical circumstances of the patients.
In practical terms, examining such a model can help psycho-oncologists identify a set of factors associated with it, rather than focusing solely on reducing the fear of relapse. If the prominent role of health anxiety is observed, cognitive-behavioral interventions can be used to correct catastrophic interpretations and reduce excessive body monitoring. If resilience is low, coping skills training, emotion regulation, and psychological flexibility can be included in the treatment plan, and if social support, family interventions, and support groups can be considered.
One of the advantages of the structural model is the possibility of simultaneous investigation of several factors affecting the fear of recurrence, however, the use of cross-sectional data to construct such models is limited and it is not possible to prove causal relationships between variables based solely on correlation. Also, differences in measurement tools, heterogeneity of cancer samples, and cultural differences can affect the results of the model. It is suggested that future research be conducted using longitudinal designs, larger samples, and different groups of patients with cancer, and the role of other variables such as emotion regulation, intolerance of uncertainty, rumination, and quality of life should also be investigated. A structural model based on resilience, social support, and health anxiety can provide a comprehensive framework for understanding the protective factors and vulnerability associated with fear of relapse and provide the ground for designing person-centered and multidimensional interventions in psycho-oncology.
