The present study aims to conduct a randomized controlled trial to assess the effect of CALM intervention and ConquerFear intervention on fear of cancer progression among Chinese patients diagnosed with advanced cancer.
Cantonese- or Mandarin-speaking Chinese patients recently diagnosed with advanced or metastatic (i.e. stage III or IV) cancer
are the age of 18 years or above
Patients with major communication difficulties
are being unwilling or unable to commit 6 psychotherapy sessions

ConquerFear intervention
BehavioralConquerFear 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 intervention
BehavioralCALM 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.
Basic Cancer Care
BehavioralBasic Cancer Care intervention for the control arm was developed to help cancer survivors with health maintenance in long-term through providing comprehensive lifestyle guidance. The intervention incorporates relaxation training, dietary and physical fitness consultations with the key goals to (1) teach relaxation techniques, (2) offer personalized diet and physical activity advice, and (3) enhance survivors' perceived control over illness, thereby leading to better adjustment to cancer. Similar to the ConquerFear intervention, Basic Cancer Care intervention consists of 6 individual sessions over 10 weeks. Each session will last 60-90 minutes and be delivered by a trained therapist, a registered dietitian, and an exercise physiologist, respectively. A hybrid mode of intervention delivery will be also used by offering participants the choice of face-to-face or online sessions.
Fear of Progression
The 12-item short version of the Fear of Progression Questionnaire (FoP-Q-SF) will be used to assess the change in total score of fear of caner progression. Each item of the FoP-Q-SF is rated on 5-point Likert scales anchored at 1 (Never) to 5 (very often). Higher scores indicate higher levels of fear of cancer progression. Total scores range from 12 to 60. A cutoff of 24-33 was used to suggest subthreshold level of fear of progression and a score of 34 or greater suggest high levels of fear of progression.
Metacognitions
The 30-items Metacognitions questionnaire (MCQ-30) will be used to assess the change of metacognitive beliefs.Each item is rated on a 4-point Likert scale with a total score ranging from 30 to 120. High scores indicate a more maladaptive metacognitive style.
Depression
Change in total scores of depression will be assessed using the Patient Health Questionnaire-9 (PHQ-9). The PHQ-9 score can range from 0 to 27, with higher scores indicative of a higher level of depression. The PHQ-9 is a reliable and valid 9-item measure of depression that has been used widely in advanced cancer patients.
Death anxiety
Change in total scores of death anxiety will be assessed by the 15-item Death and Dying Distress Scale (DDDS). The DDS score can range from 0 to 90, with higher scores indicative of a higher level of death anxiety.
