Acceptance and Commitment Therapy (ACT) in Inflammatory Bowel Disease

A Randomized Controlled Trial of Acceptance and Commitment Therapy (ACT) in Inflammatory Bowel Disease

Over 18,000 Irish people are affected by the inflammatory bowel diseases (IBD), Crohn's disease and ulcerative colitis. These illnesses often arise at a young age and can be associated with significant physical disability. In addition, there is considerable psychosocial disability associated with IBD. Previous studies have suggested that simple psychological interventions may be valuable in improving quality of life and may even improve disease activity. However, there has been no comprehensive trial to determine the precise effect of psychological interventions on quality of life (QOL), stress or disease activity. Our aim is to conduct a randomised controlled trial of a simple psychological intervention to determine it's effect on QOL and stress

The inflammatory bowel diseases (IBD), which include Crohn's disease and ulcerative colitis, are chronic conditions that often arise in young patients and may lead to a lifetime of physical disability. Psychological disabilities are also prevalent in patients with chronic diseases and epidemiological studies indicate that IBD patients are at increased risk of anxiety and mood disorders, with depression rates more than double that of matched community samples (27% versus 12%). IBD patients are also at increased risk of illness-related psychological difficulties including body image concerns, sexual problems and reduced self-esteem. Therapeutic approaches to inflammatory bowel disease naturally focus on treatments that minimise disease activity and normalise physical function. Thus, there has been considerable research conducted on 5 ASA medications, steroids, immune modulators and biologic agents. In contrast, little attention has been paid to important, but 'low-technology', issues including quality of life and psychological comorbidities including depression, anxiety, stress, altered body image, sexuality, illness attitudes, self-esteem and other psychosocial IBD co-morbidities. Nevertheless, patient reported data and outcomes are increasingly being incorporated into research that informs strategic healthcare documents that, in turn, help formulate healthcare policy. Contemporary European and British guidelines now emphasise the benefits of a patient centred service that supplies psychological as well as medical support. In addition to the burden that psychological disease places upon IBD patients, there is evidence that psychological morbidity and stress is also associated with disease activity. IBD patients with depression experience more disease flares than those with no diagnosable psychological condition and a Canadian study has also suggested that stress can be associated with disease flares. In contrast, a Spanish study on 163 patients concluded that stressful life events do not trigger exacerbations in IBD patients. Overall, it is likely that the relationship between stress and disease activity is bi-directional with each one influencing the other to some extent. To date, interventions aimed at reducing psychological distress in IBD have tended to focus on either psychological education, stress management including relaxation techniques and autogenic training, psychodynamic psychotherapy, cognitive behavioral therapy and hypnosis. Studies have been variable with regard to psychological content and almost all had multiple methodological limitations, making it difficult to draw conclusions about the value of these interventions. Perhaps the most comprehensive review of psychological studies in IBD, which included 16 studies, concluded that while psychological interventions can make a positive contribution to best practice multidisciplinary IBD treatment, well designed studies are needed to determine the efficacy of different treatments. We aim to conduct a multicenter randomised controlled trial to determine the efficacy of Acceptance and Commitment Therapy (ACT) on the psychological wellbeing of IBD patients. We aim to include 80 patients in this longitudinal study (40 in each arm). IBD patients attending St Vincent's University Hospital and Beaumont Hospital are treated in protocol driven inflammatory bowel disease clinics with therapy adhering to international treatment guidelines. We currently use protocols developed by the European Crohn's and Colitis Organisation (ECCO) and American Gastroenterology Association (AGA). Our care incorporates formalised multidisciplinary teamwork with standardised clinical monitoring, use of contemporary biomarkers of disease activity and a full range of current therapies including 5-ASA and steroid medications, immunological therapies, open and laparoscopic surgery as appropriate, endoscopic treatment as necessary and the latest biological agents as per protocol. Thus, the study will take place in a clinical environment in which we adhere to the most modern practices. Initial assessment Biological assessment The initial assessment will comprise standardised and validated questionnaires to determine biological status. Specifically, we will assess: Demographic data Region, urban/rural, race, age, education, martial status, family history, occupation, employment status, smoking and alcohol history Nutritional status Body Mass Index Exercise status Godin Leisure-Time Exercise Questionnaire IBD history Disease type, duration, clinical, therapeutic and surgical history, Hospital admissions and visits, GP visits Disease activity Harvey Bradshaw Index (CD), Mayo Score (UC), physical examination Medication adherence Medication Adherence Report Scale 5 (MARS5) Laboratory indices Biochemical, immunological and haematological variables, faecal calprotectin, hair cortisol Psychological assessment This will include validated instruments to build a structured picture of the IBD illness. We will assess: General Quality of Life Short Form 12, Healthy days IBD specific QOL Short Health Scale Stress/anxiety/depression Depression Anxiety Stress Scales (DASS) 21 and Stress Thermometer Self Esteem Rosenberg Self Esteem Survey Body Image Modified Hopwood Body Image Scale Disease acceptance Acceptance and Action Questionnaire - Revised Interventions Group 1) Control (n=40) The control group will consist of 40 patients who will who will not receive treatment for 26 weeks and will then receive the ACT program. Group 2) Acceptance and Commitment therapy (n=40) ACT is a behavioural therapeutic approach that uses processes of acceptance, mindfulness, commitment and behaviour change to increase psychological flexibility. In terms of ACT for IBS specifically, its use is in guiding patients to develop a willingness to come in contact with their unpleasant experiences of physical symptoms and with the feeling of embarrassment, anticipatory anxiety and distressing thoughts commonly associated with IBS. The former agenda of trying to eliminate symptoms and distressing cognitive and emotional states can then be replaced by an agenda focusing on creating a more meaningful life with IBS. Assessments during intervention period Weekly assessments will be performed during the intervention period. These will include the Harvey Bradshaw Index (CD), Mayo Score (UC), Short Health Scale, (DASS) 21 and Stress Thermometer Eight week assessment Biological assessment Medication adherence Medication Adherence Report Scale 5 (MARS5) Nutritional status Body Mass Index Exercise status Godin Leisure-Time Exercise Questionnaire Disease activity indices Harvey Bradshaw Index (CD), Mayo Score (UC) Laboratory indices Biochemical, immunological and haematological variables, faecal calprotectin, hair cortisol Psychological assessment General Quality of Life Short Form 12, Healthy days IBD specific QOL Short Health Scale Anxiety/Depression Beck Depression Inventory, Beck Anxiety Inventory Stress Depression Anxiety Stress Scales (DASS) 21 and Stress Thermometer Self Esteem Rosenberg Self Esteem Survey Body Image Modified Hopwood Body Image Scale Sexuality Modified Golombok-Rust Inventory Disease acceptance Acceptance and Action Questionnaire - Revised 26 week assessment Repeat of 8 week assessment Hair Cortisol Measurement The effects of stress are mediated by the stress hormone cortisol. Cortisol is involved in the regulation of glucose and lipid metabolism, body composition, and the immune system. Cortisol is traditionally measured in serum or saliva. However, because cortisol is secreted in a circadian rhythm and with pulses, the timing of sample collection is crucial when measuring cortisol in serum or saliva. In addition, cortisol is a stress hormone, and acute stress, such as that caused by the research setting or venepuncture, will influence measurements. A single measurement of cortisol in serum or saliva therefore poorly reflects medium and long-term cortisol levels. An alternative method to measure cortisol is in scalp hair. This method offers long-term measurements of cortisol levels, with 1cm of hair representing cortisol levels of approximately one month. In the last few years, the measurement of cortisol in scalp hair has been well validated. We will measure hair cortisol at the initial assessment, at the conclusion of therapy (8 weeks) and at the 26 week visit.

This group will consist of patients who will receive ACT therapy.This intervention will run with 8-12 participants in each group for a duration of 8 weeks. Each group session will last 1-1.5 hours.

The control group will consist of patients who will receive no ACT therapy during the 26 week st udy period

This intervention will run with 12-15 participants in each group for a duration of 8 weeks. Each group session will last 1-1.5 hours.
