ConquerFear-group: Feasibility study with pilot results of a psychological intervention for fear of cancer recurrence delivered in groups

ConquerFear-Group: A randomized controlled trial of an online-delivered group-based psychological intervention for fear of cancer recurrence in breast cancer survivors

OBJECTIVE

Fear of cancer recurrence (FCR) is a distressing concern among cancer survivors. Interventions to address FCR need to be effective but also accessible and low cost. This randomized controlled trial evaluated the efficacy of an online group-based psychological intervention for FCR (ConquerFear-Group).

METHODS

Eligible breast cancer (BC) survivors had completed primary treatment 3 months-5 years previously, were ≥18 years, and scored ≥22 on the Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF). Participants were randomized to online ConquerFear-Group (focusing on metacognitive strategies, values-clarification, and education about follow-up behavior) or online group-based relaxation training (active control). Questionnaires were completed at baseline (T1), 1 week post-intervention (T2), three (T3) and six (T4) months later. The primary outcome was FCR (FCRI total). A number of secondary and process outcomes were also collected. Treatment effects were evaluated with mixed linear models.

RESULTS

Of 866 eligible BC survivors, 475 (55%) completed the FCR screening, and 85 (18%) were randomized to ConquerFear-Group or relaxation training (2 × 6 groups). Compared with control participants, ConquerFear-Group participants experienced larger reductions in FCR (Cohen's d = 0.47, p = 0.001) and FCR severity (d = 0.57, p < 0.001), as well as mindfulness and decentering from baseline through follow-up, and improvements in emotion regulation (T2), worry (T2, T3) and rumination (T2) at some time points.

CONCLUSIONS

The results demonstrated statistically significant and stable effects of ConquerFear-Group on FCR that were maintained over a 6-month period. It is suggested to investigate the program in a real-life setting, where a pragmatic trial can further demonstrate feasibility and effectiveness.

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.

Impact of the CALM intervention on breast cancer patients during the COVID-19 pandemic

OBJECTIVE

The COVID-19 outbreak has adversely affected breast cancer patients both physically and mentally. Managing Cancer and Living Meaningfully (CALM) is a psychological intervention that is easy to implement. It also decreases the possibility of virus transmission because it can be administered online. Therefore, this study investigated the effects of CALM on the sleep quality, memory, psychological distress, and quality of life (QoL) of breast cancer patients during the ongoing COVID-19 pandemic.

METHODS

Sixty breast cancer patients were recruited and randomly assigned to a CALM group and a Care as Usual (CAU) group. They filled in questionnaires before and after the CALM intervention and CAU. These included the Sleep Quality Scale (SQS), Prospective Memory Scale (PM), Retrospective Memory Scale (RM), Psychological Distress Thermometer (DT), and Quality of life (QoL) Scale.

RESULTS

The scores of all the aforementioned scales after the CALM intervention (ACM) were significantly lower compared to the said scores before the CALM intervention (BCM) and after Care as Usual (ACU) (t = 12.369/8.013, t = 8.632/4.583, t = 7.500/6.900, t = 12.479/9.780, t = 12.224/6.729 respectively, P < 0.05) There was a linear correlation between the QoL, DT, and SQS scores.

CONCLUSION

CALM is an effective psychotherapy for breast cancer patients, especially during the COVID-19 pandemic, for improving the QoL because it relieves psychological distress and enhances sleep quality.

Study protocol for the evaluation of Fear-Less: a stepped-care program for fear of cancer recurrence in survivors with early-stage disease

BACKGROUND

Fear of cancer recurrence (FCR) is a significant unmet need amongst cancer survivors and is consistently associated with psychological distress and impaired quality of life. Psychological interventions for FCR, such as ConquerFear, have demonstrated efficacy in reducing FCR and improving emotional wellbeing. Unfortunately, there are barriers to the uptake of evidence-based FCR treatments in clinical practice. A stepped-care FCR treatment model may overcome these barriers and has demonstrated potential in people with advanced melanoma. This study aims to evaluate the acceptability, feasibility, and impact of a stepped-care FCR treatment model (Fear-Less) in people with other cancer types, who have completed treatment with curative intent.

METHODS

Sixty people with early-stage cancer (defined as individuals who have received treatment with curative intent and with no metastatic disease) will be screened for FCR using the Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF). Individuals reporting moderate FCR (FCRI-SF between 13 and 21) will be offered a clinician-guided self-management resource; those reporting high FCR (FCRI-SF ≥ 22) will be offered individual therapy according to the ConquerFear protocol. Participants will complete purpose-built evaluation surveys assessing their FCR screening and intervention experiences. Clinicians will also complete a survey regarding their experiences of the treatment model. Fear-Less will be evaluated in terms of (1) acceptability (i.e., patient and clinician experience), (2) feasibility (i.e., referral uptake, treatment adherence, and time taken to screen and deliver interventions), and (3) impact (i.e., pre- to post-intervention FCR changes).

DISCUSSION

The Fear-Less stepped-care model is a novel framework for screening FCR and stratifying survivors to the appropriate level of treatment. Our study will provide an indication of whether Fear-Less is a feasible and acceptable FCR model of care amongst survivors with early-stage disease and inform further investigations of this model.
