This study aims to evaluate the effectiveness of metacognitive therapy (MCT) in reducing fear of cancer recurrence (FCR) among cancer survivors. With advances in cancer treatment, more patients are surviving cancer. However, many survivors continue to experience fear of cancer recurrence, which can affect their emotional well-being, quality of life, and ability to return to normal daily activities. In this study, participants will receive a structured psychological intervention adapted from the ConquerFear program. This program has been modified to better fit local cultural needs. Participants will be randomly assigned to receive either metacognitive therapy or relaxation therapy. The study will compare the effects of these interventions on reducing fear of cancer recurrence, as well as their impact on emotional distress and quality of life. The results of this study may help develop effective psychological treatments to support cancer survivors in managing fear of recurrence and improving overall well-being.

Cancer has been the leading cause of death in Taiwan since 1982. The World Health Organization emphasizes that psychological and social care are as important as medical treatment in cancer care. Cancer patients experience multidimensional stress, including physical, psychological, and existential challenges, often accompanied by symptoms such as pain, anxiety, depression, insomnia, hopelessness, and fear of death. Advances in cancer treatment, including early detection, precision medicine, immunotherapy, and targeted therapy, have significantly improved survival rates. However, cancer survivors frequently experience ongoing physical, psychological, and social challenges. Fear of cancer recurrence (FCR) is one of the most prevalent and clinically significant concerns among cancer survivors, with prevalence rates ranging from 22% to 87% (Simard et al., 2013). Excessive FCR is associated with increased anxiety and depression, and may interfere with return to work and normal daily functioning. FCR has become a major focus in psycho-oncology worldwide, as it significantly affects psychological well-being, quality of life, and health-related behaviors among cancer survivors. This study aims to evaluate the effectiveness of metacognitive therapy (MCT) in reducing FCR among cancer survivors. MCT targets maladaptive metacognitive processes such as worry and rumination, which are central to the maintenance of emotional distress. The intervention is adapted from the Hong Kong version of the ConquerFear program and culturally modified for local use. A randomized controlled design will be used to compare the effectiveness of the adapted ConquerFear intervention with a relaxation therapy control condition in reducing FCR. In addition, the study will explore whether coping styles moderate the effectiveness of the intervention. The findings of this study are expected to provide evidence for developing effective psychological interventions to improve mental health outcomes in cancer survivors.
