Managing Fear of Cancer Progression Metacognition-based Vs Supportive-expressive Based Approaches

ConquerFear is a manualized intervention, consists of six individual sessions over 10 weeks. The key goals of this intervention are the following: (1) teach strategies for controlling worry and excessive threat monitoring, (2) modify underlying unhelpful beliefs about worry, (3) develop appropriate monitoring and screening behaviours, (4) encourage acceptance of the uncertainty brought about by a cancer diagnosis, and (5) clarify values and encourage engagement in values-based goal setting (19). Each session will last 60-90 minutes and be delivered by a trained therapist. After each session, participants will be given home-based exercises to practice the skills learned in the sessions. With the uncertainty surrounding the COVID-19 pandemic, instead of face-to-face sessions only, a hybrid mode of intervention delivery will be used by offering participants the choice of face-to-face or online sessions.

CALM is a semi-structured, manualized, individual psychotherapy intervention designed for patients with advanced cancer. It includes 3-6 individual therapy sessions, with each approximately lasts 45-60 minutes, delivered over 3-6 months. The sessions cover 4 domains: 1) symptom management and communication with health care providers; 2) changes in self and relations with close others; 3) sense of meaning and purpose; and 4) the future and mortality. All modules will be addressed with each patient, but the sequencing and time devoted to each domain can be varied, based on the concerns that are most relevant to each patient.
