Study protocol of ConquerFear-HK: a randomised controlled trial of a metacognition-based, manualised intervention for fear of cancer recurrence among Chinese cancer survivors.

INTRODUCTION: Fear of cancer recurrence (FCR) is a prevalent and frequently debilitating response to a cancer diagnosis, affecting a substantial proportion of cancer survivors. Approximately 30% of local Hong Kong Chinese cancer survivors in a recent survey reportedly experienced persistent high FCR over the first-year post-surgery. This was associated with lower levels of psychological well-being and quality of life. A manualised intervention (ConquerFear) developed primarily based on the Self-Regulatory Executive Function Model and the Rational Frame Theory, has been found to reduce FCR effectively among Caucasian cancer survivors. The intervention now has been adapted to a Chinese context; ConquerFear-HK. The primary aim of this study is to evaluate its efficacy vs a standard-survivorship-care control (BasicCancerCare) in FCR improvement in a randomised control trial (RCT). METHODS AND ANALYSIS: In this RCT, using the sealed envelope method, 174 eligible Chinese cancer survivors will be randomised to either the ConquerFear-HK or BasicCancerCare intervention. Both interventions include six sessions over 10 weeks, which will be delivered via face to face or online by trained therapists. The ConquerFear-HK intervention incorporates value classification, metacognitive therapy, attentional training, detached mindfulness and psychoeducation; BasicCancerCare includes relaxation training, dietary and physical activity consultations. Participants will be assessed at prior randomisation (baseline; T0), immediately postintervention (T1), 3 months (T2) and 6 months postintervention (T3) on the measures of FCR (Fear of Cancer Recurrence Inventory) as a primary outcome; metacognition (30-item Metacognitions Quesionnaire) and cognitive attentional syndrome (Cognitive-attentional Syndrome Questionnaire) as process outcomes; psychological distress (Hospital Anxiety and Depression Scale), cancer-related distress (Chinese Impact of Events Scale), quality of life (European Organisation for Research and Treatment of Cancer Quality of Life Core Questionnaire) and treatment satisfaction are secondary outcomes. ETHICS AND DISSEMINATION: Ethics approval has been obtained from HKU/HA HKW Institutional Review Board (ref: UW19-183). The patients/participants provide their written informed consent to participate in this study. The study results will be disseminated through international peer-review publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT04568226.

Dietary decision-making in Chinese breast cancer survivors: A qualitative study.

OBJECTIVE: To explore the dietary practices and decision-making process among Chinese breast cancer (BCA) survivors. METHODS: Using a grounded theory approach, this qualitative study involved individual semi-structured interviews with 30 BCA survivors. All interviews were audio-recorded and transcribed verbatim for analysis. RESULTS: Most of the participants reported making long-term diet modification. Key themes were grouped into three stages: (1) Motivation, (2) Diet modification, and (3) Maintenance. Most participants reported to be motivated by cancer causal attributions formulated through the evaluation of past dietary habits. Others embarked on changes out of compliance to social expectations. BCA survivors interviewed were willing to make trade-offs for health, but also influenced by peer and traditional Chinese beliefs. The lack of awareness of dietary guidelines was a crucial barrier to adopting healthy eating. Lastly, maintenance of newly formed dietary habits was reinforced by positive feedback but hindered by a lack of both self-efficacy and social support. CONCLUSIONS: While the majority of BCA survivors expressed willingness to improve their diets, changes made were often inconsistent with existing dietary recommendations. PRACTICE IMPLICATIONS: Future interventions may target factors at different decision-making stages: guiding evaluation of past diet, building self-efficacy and giving approval to encourage maintenance of healthy dietary behaviors.

Dietary changes adopted by Chinese colorectal cancer patients: A qualitative study.

OBJECTIVE: To explore influences on post-diagnosis dietary decision-making in colorectal cancer survivors (CRC) for future intervention development. METHODS: Individual semi-structured interviews were conducted with 30 CRC survivors. All interviews were recorded and transcribed verbatim for grounded theory analysis. RESULTS: Most CRC survivors interviewed reported making both short- and long-term changes post-diagnosis, influenced by physical symptoms and personal beliefs: short-term treatment-driven changes to facilitate recovery, manage treatment side-effects and avoid disruption in treatment; short-term 'patient role' driven changes heavily influenced by family members and cultural beliefs; long-term changes driven by residual symptoms and illness beliefs, including cancer causal attributions and beliefs about preventing future recurrences. Traditional Chinese medicinal (TCM) beliefs were influential in both short- and long-term dietary decision-making, which may explain why survivors focused on specific food items rather than food patterns. CONCLUSION: While our findings suggested that the majority of CRC survivors made dietary changes post-diagnosis, their dietary pattern and motivation may change over the course of their illness trajectory. Also, the types of changes made are often not consistent with existing dietary recommendations. It is necessary to consider illness perception and cultural beliefs when delivering dietary care or developing interventions for this population.
