Group Metacognitive Therapy for Anxiety and Depression in Cancer Survivors

Study Overview
=================
Brief Summary
-----------------
This study aims to test the potential of group metacognitive therapy in alleviating emotional distress in cancer survivors. The investigators aim to find out if a group based approach is acceptable to patients and feasible to deliver in a routine clinical health psychology service.

Detailed Description
-----------------
Survival rates in cancer continue to improve, with over 2 million adult cancer survivors in the United Kingdom, projected to increase to 4 million by 2030. Around 25% of these survivors require treatment for clinical levels of emotional distress. Current pharmacological treatments are not very effective and are not well tolerated by patients, who prefer psychological treatments. However, meta-analyses of well-controlled studies of psychological treatments indicate that these achieve only small effect sizes. Reflecting this limited efficacy in the face of the need for psychological treatment, the National Cancer Survivorship Research Initiative highlighted development and evaluation of practically feasible interventions for depression and anxiety in cancer survivors as an urgent research priority. It is recognised that current influential psychotherapeutic approaches need to be modified to meet the specific needs associated with cancer. However modifications have been pragmatic rather than theory-driven and have not improved efficacy. The study addresses the stages of 'development' and 'piloting and feasibility' in Medical Research Council guidance on intervention development, albeit with a relatively well-defined starting point given existing evidence for efficacy of metacognitive therapy (MCT) in other settings and promising preliminary evidence of applicability in cancer. The investigators will conduct a phase I open trial to test the potential efficacy of group MCT in cancer survivors and the hypothesised causal metacognitive mechanisms underpinning treatment response.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Group Metacognitive Therapy<br>Group metacognitive therapy (MCT) is a brief psychological intervention designed to be delivered in small groups of 4-8 patients over a course of six, 90 minute sessions conducted on a weekly basis | Behavioral: Group Metacognitive Therapy<br>* Group MCT is based on a manualised protocol and is structured in the following way. In session 1, idiosyncratic case formulations based on the generic metacognitive model are developed for each participant. Socialization helps patients to understand that worry/rumination and unhelpful coping strategies are maintaining emotional distress. Patients are then introduced to, and practice well established treatment techniques to modify negative beliefs about uncontrollability of rumination/worry. Later sessions address relapse prevention and involves modifying remaining use of the 'cognitive attentional syndrome', reviewing residual conviction in positive and negative beliefs and consolidating and strengthening alternative ways of responding to negative thoughts.<br>|
