Plain English Summary
Background and study aims
Anorexia nervosa (AN) is a serious eating disorder in which people keep their body weight low by dieting, vomiting, using laxatives or excessively exercising. It affects men and women of all ages, but is most common in young women. AN affects the whole body, and can lead to serious mental health issues, such as depression and problems with cognitive (thinking, learning and memory), as well as damage to major organs such as the heart and kidneys. If the weight loss is particularly severe, then hospitalizing the sufferer to help them gain weight is the main treatment option. The length of hospital stay and death rate in the year after admission for patients with severe anorexia nervosa is higher than for other psychiatric conditions. It has been found that that actively involving the family in shared management reduces the readmission rate and improves both patient and family well-being. It has also been found that self-management materials for patients also improves outcomes. The aim of this study is examine whether adding self-management materials for both carers and patients improves both patient and carer outcomes and service use in the year following specialist inpatient treatment for patients with severe anorexia nervosa.
Who can participate?
Anorexia patients aged 17 or over who have a carer including family and/or friends willing and able to provide some aftercare support) who is also willing to take part
What does the study involve?
Patients and their carers are randomly allocated to one of two groups. Those in the first group receive usual treatment alone. Those in the second group receive usual treatment with the addition of the shared self-management materials, which are available online. The self-management materials are available on two online platforms (one for patients and one for carers) and contain self-management tools which support the individual and the family, such as workbooks, DVD, vodcasts, questionnaires, feedback, with chat line and e mail support. Patients’ and carers’ wellbeing are measured on admission and at 3-monthly intervals over the following 18 months using multi-method assessment techniques. In addition, service use, costs, and the role of prospective mediators and moderators of clinical outcomes are measured.
What are the possible benefits and risks of participating?
Findings from previous scientific studies show that both parties (carers and patients) can benefit from this type of program. Carers experience less stress and burden, and patients maintain the changes from inpatient care more effectively. There are no notable risks involved with participating.
Where is the study run from?
22 NHS or non-NHS inpatient/daycare units in England and Scotland (UK)
When is the study starting and how long is it expected to run for?
November 2016 to October 2021
Who is funding the study?
National Insitute for Health Research - Health Technology Assessment Programme (UK)

| Scientific title | A multicentre, investigator-blinded, randomised, 18 month, parallel group, superiority study to examine whether the addition of a patient and carer shared management intervention improves patient wellbeing following inpatient treatment for anorexia nervosa |
| Study acronym | TRIANGLE |
| Study hypothesis | The overall aim is to compare the effectiveness and cost-effectiveness of adding a shared management intervention aimed at reducing patients’ distress to treatment as usual for inpatients with anorexia nervosa. Using a randomized controlled trial, we will examine whether there is an improvement in eating disorder symptoms with less care-giving burden and service use in the 18 months post-admission. Primary objective: To examine whether adding a guided shared management intervention for patients and carers aimed at reducing patients’ distress is more effective than usual care in the 18 months following admission. Secondary objectives: 1. To assess the following secondary hypotheses as to whether augmenting aftercare treatment as usual with a combined skills-sharing intervention will: 1.1. Improve BMI and increase quality of life for patients in the year following admission 1.2. Reduce distress, burden and increase quality of life for carers in the year following admission 1.3. Reduce days in hospital in the 18 months post-discharge 1.4. Be more cost-effective than treatment as usual in terms of distress and quality-adjusted life years gained in the 18 months following admission 2. To have available a set of theoretically-grounded, empirically-supported tools including highly-teachable health behaviour techniques for patients, carers, and professionals that can be readily disseminated 3. To examine the process variables that are thought to mediate and moderate change for patients and caregivers 3.1. To determine the impact of the combined intervention on variables targeted by the various component parts of the intervention (e.g. accommodation, expressed emotion, interpersonal functioning) 3.2. To assess the fidelity of the intervention using (1) rating scales, (2) thematic analysis of guidance sessions (3) feedback (qualitative and quantitative) from patients and caregivers 3.3. To conduct exploratory analyses of whether BMI, level of psychopathology, duration of illness, type of admission (voluntary/involuntary) has an impact on overall outcome and whether there is an interaction with type of aftercare given |

| Intervention | Participants are randomised to one of two groups by King’s Clinical Trials Unit based on patient body mass index and clinical service. Intervention arm: Participants and their carers will be able to access the intervention materials on the study website. The intervention materials consist of: a workbook, a library of short video-clips; 8 online group forum sessions and up to 6 joint Skype sessions (patient-carer) with a health professional. Participants will be able to use the workbook and video-clips and to take part in 4 online group forums during hospital admission. At discharge, they will be able to participate in 4 additional online group forums and will be able to receive up to 6 joint Skype sessions with a health professional. Participants will complete regular assessments up to 18 months post-randomisation (i.e. baseline; monthly surveys; questionnaires at 3, 6, 9, 12 and 18 months). Participants will receive a visual feedback of their scores over time, after completing some of these questionnaires. The questionnaires will be completed on the study website. Control arm: Participants and their carers will be randomised by the King’s Clinical Trials Unit based on patient body mass index and clinical service. Those allocated to the control condition will complete regular assessments on the study website (i.e. baseline questionnaires; weekly surveys; questionnaires 3-, 6-, 9-, 12-, and 18-month post-randomisation). Participants will receive a visual feedback of their scores over time, after completing some of these questionnaires. |

| Publication and dissemination plan | The overall aim is to inform clinical practice within the NHS. Given that a large proportion of the intervention includes materials that are in production with a minimal amount of guidance, we anticipate that the intervention is scalable with the possibility for high reach. Indeed, past research suggests that interventions requiring limited professional input may be more readily disseminated (69). The dissemination plan will target various audiences at different levels: 1. Professional: Planned submission of papers including the study protocol to leading journals. Authorship will determined based on the contribution to each paper. Planned presentation of findings at eating disorder, psychiatric, student counselling and primary care conferences etc. We will disseminate the results to the special interest groups within the professional bodies of the multiple disciplines involved in the care of this group of patients (nurses, psychology, occupational therapy, dieticians, social workers, etc.). Data sharing with potential collaborators (UK and International) will be encouraged. 2. Policy: A full report with the executive summary will be sent to all NHS commissioning agencies. The co-applicant LG, COO of BEAT, will use this to assist in dialogues with policy makers, including MPs. 3. Patients and public: BEAT will coordinate this aspect of dissemination. Dissemination strategies will include presentations/blogs on eating disorder charities and carer and user websites and communication channels (FEAST, BEAT, Students Mind, etc.) at yearly carers’ and users’ workshops, media articles, discussion forums, website postings, and schools’ training events. Training will be conducted through presentations, discussions, small groups teaching and large group seminars. A summary of findings will be made available on the websites of the key charities and the Psychological Medicine website at the Institute of Psychiatry. All participants will also be sent newsletters and will have free admission to the carers conference. 4. Media: The Press Offices at South London and Kings College will co-ordinate dissemination to the media. The study team aims to present the results on radio Woman's Hour and All in the Mind. Patient participation groups, newspapers and neighbourhood organizations will also be contacted to disseminate findings. |
