Plain English summary of protocol

Background and study aims
Individuals who are at risk of rare familial dementias, specifically frontotemporal dementia (fFTD) and familial Alzheimer’s disease (FAD) report struggling with guilt and anxiety about the risk to themselves and their children, decisions about whether to get tested, uncertainty about the onset of symptoms, and see their risk of potentially developing dementia as a barrier in life. Ongoing work suggests that these psychological difficulties also affect their ability to participate and remain in clinical drug trials, compromising the development of new treatments. Despite this there are currently no tailored interventions available to support people with the psychological consequences of living at risk of genetic dementias.
This study aims to determine the effectiveness of the IWARF blended in-person/online support programme in improving mental wellbeing for people living at risk of genetic dementias as well as understand people's experience of using this programme through interviews after they have used it.

Who can participate?
People aged 18 years and over with a first-degree relative who is symptomatic and/or a known mutation carrier for an inheritable form of dementia (either familial Alzheimer’s disease [FAD] or familial Fronto-Temporal Dementia [fFTD])

What does the study involve?
Participants will complete some questionnaires and then be randomly allocated to use the online programme or to their usual care. Those assigned to the online programme will be invited to take part in an 8-week intervention comprising 10 online modules in 6 topic areas with additional psychoeducational videos and three video conference check-in sessions. Initially, participants will be shown an introductory video to demonstrate how to use the intervention and to explain the different features. Throughout the programme participants will have the option to contact the IWARF research team via email if they have any problems or queries.
Participants will be invited to complete the modules that correspond to their needs, at their own pace, with check-in sessions occurring at intervention-beginning, middle and end (facilitated by a Research Assistant or Research Fellow who will be trained/supervised by experienced Clinical Psychologists and researchers). Modules cover issues identified as important during the intervention development stages (e.g., rumination about risk or positive genetic status; uncertainty; making the most of life at risk; isolation). A mixture of materials will be used, including informational videos and independent activities, most drawing on Acceptance and Commitment Therapy (e.g., using mindfulness-based acceptance techniques to manage rumination).
All participants taking part will be invited to complete questionnaires again at 8 weeks and 6 months after the start of the study, to understand if there has been greater change in their wellbeing after the intervention compared to usual treatment. Participants completing the online programme will also be invited to interviews about their experience.

What are the possible benefits and risks of participating?
This intervention is uniquely tailored to the needs of people living at risk of familial dementias. As a result, participants might feel better equipped to manage some of the practical and emotional aspects associated with living at risk of rare familial dementias. There are no clear risks to participation and should participants feel upset or distressed by any of the questions and/or content they will be able to discuss these in person with members of the research team during the check-in sessions built into the intervention.

Scientific titleImproving Wellbeing Associated with Rare Familial dementias (IWARF): an online support programme to improve psychological outcomes in people living at risk of inheriting either familial frontotemporal dementia or familial Alzheimer's disease
Study acronymIWARF
Study objectivesIt is hypothesised that the Improving Wellbeing Associated with Rare Familial dementias (IWARF) online support programme may lead to improvements in a range of psychological outcomes (e.g., anxiety, depression, distress, wellbeing, quality of life etc) for people living at risk of inheriting either familial Fronto-Temporal Dementia (fFTD) or Familial Alzheimer's disease (FAD)
Ethics approval(s)

Approved 10/01/2024, UCL Research Ethics Committee (University College London, 2 Taviton St, London, WC1E 6BT, United Kingdom; +44 (0)20 7679 8717; ethics@ucl.ac.uk), ref: 8545/008

Health condition(s) or problem(s) studiedFamilial dementias and specifically familial Fronto-Temporal Dementia (fFDT) and Familial Alzheimer's Disease (FAD)
InterventionThe aim of this study is to test the effectiveness of an online support programme (IWARF) via a randomised controlled trial (RCT) to improve a range of psychological outcomes for people living at risk of inheriting either fFTD or FAD. Specifically, this study will examine whether the online support programme is associated with improvements in wellbeing and reductions in depression and anxiety reductions in psychological inflexibility and experiential avoidance (theoretical tenets of Acceptance and Commitment Therapy) and improvements in overall quality of life and loneliness. The study has been designed as a two-arm RCT, whereby participants will be randomised to (1) the intervention group that will use IWARF, the online training and support programme, or (2) a waiting list control group who will access the rare dementia support website. In an embedded process evaluation, intervention participants will also be asked to complete a scale of system usability and be invited to an interview to discuss their experience. Randomisation will be provided via a secure online platform hosted by NWORTH CTU, Bangor University. Once consent and baseline measures have been completed participants will be entered into the randomisation system. A dynamic adaptive randomisation algorithm will be used to maintain the allocation ratio of 1:1 and balanced within stratification variables. Randomisation will be stratified by diagnosis (i.e., FAD, fFTD) and at-risk status (i.e. known mutation carrier, known non-carrier, unknown).

Participants assigned to the online programme will be invited to take part in an 8-week intervention comprising 10 online modules in 6 topic areas with additional psychoeducational videos and three video conference check-in sessions. Initially, participants will be shown an introductory video to demonstrate how to use the intervention and to explain the different features. Throughout the programme participants will have the option to contact the IWARF research team via email if they have any problems or queries.

Participants will be invited to complete the modules that correspond to their needs, at their own pace, with check-in sessions occurring at intervention-beginning, middle and end (facilitated by a Research Assistant or Research Fellow who will be trained/supervised by experienced Clinical Psychologists and researchers). Modules cover issues identified as important during the intervention development stages (e.g., rumination about risk or positive genetic status; uncertainty; making the most of life at risk; isolation). A mixture of materials will be used, including informational videos and independent activities, most drawing on Acceptance and Commitment Therapy (e.g., using mindfulness-based acceptance techniques to manage rumination).

All participants taking part will be invited to complete questionnaires again at 8 weeks and 6 months after the start of the study, to understand if there has been greater change in their wellbeing after the intervention compared to usual treatment. Participants completing the online programme will also be invited to interviews about their experience.
