Transition Care in Anorexia Nervosa Through Guidance Online from Peer and Carer Expertise (TRIANGLE)

Posted 19/03/2018


TRIANGLE is a multi-centre study which investigates transitions from intensive hospital treatment for anorexia nervosa (inpatient or day care) to home, so that in the future we can make these difficult periods less stressful for both patients and carers. The research aims to examine which level of information and support may be helpful to patients and their carers during treatment and following discharge. The TRIANGLE trial is funded by the National Institute for Health Research, Health Technology Assessment (NIHR HTA) programme (project ref number 14/68/09).  

Who can take part?  

To take part patients must be:  

  • Adults aged 17 or over. 
  • DSM-5 diagnosis of Anorexia Nervosa or subclinical/atypical Anorexia Nervosa, with a body mass index (BMI) of < 18.5 kg/m2. 
  • Admitted to an inpatient unit or attending day-care for a minimum of 4 days/week. 
  • Carer (family member or friend) willing to participate willing and able to provide some aftercare support. 
  • Consent within 2 months from admission to hospital. 
  • Access to an electronic device (e.g. mobile phone, computer, laptop, tablet) and the internet in order to use the study’s website.  

Eligibility will be fully assessed by the hospital team.  

What does the study involve?  

If you decide to take part, your involvement in the project will last 18 months from when you are first recruited. A chance-related system will determine your study group allocation and you will be asked to complete some questionnaires throughout the 18 months. You will receive access to a self-monitoring tool and depending on which group you are allocated to you will also receive access to some information/materials, whilst still receiving support from your clinical team. At the end of the study all participants will have access to the study materials.
