Plain English Summary

Background and study aims
Resilience refers to one’s ability to ‘bounce back’ and cope successfully in the face of life challenges. Strengthening the ability of people with dementia to bounce back in the face of a dementia diagnosis may provide the building blocks to create an environment that maximises their functioning, social connectedness and social performances. This study seeks to find out if it is possible to create such an environment.

Who can participate?
Older people over the age of 60 with memory problems/dementia who live at home in the community and their primary carers

What does the study involve?
All participants will receive a special programme of activities which will run over 15 weeks. These activities will have 3 key things:
1) A 7-week programme, (1 hour twice a week), for people with memory problems/dementia which consists of group activities, focused on promoting and maintaining their mental ability. There will be an average of 5 people in each group and the programme will be delivered by a health professional
2) An 8-week physical exercise programme, (1 hour per week for 4 weeks and 2 hours per week for 4 weeks), for people with memory problems/dementia delivered by an exercise expert. Participants will be supported by older people in the community to complete the exercises.
3) An educational programme which will have three parts (i) a 1 hour programme on dementia for members of the public delivered by a person trained in dementia care (ii) a 6 week educational programme for carers, (1 hour 40 mins a week), delivered by members of the research team (iii) a dementia training workshop for GP’s (1.5 hours) delivered by a GP trained in dementia care.

What are the possible benefits and risks of participating?
Taking part in this study will help us find out whether people with memory problems/dementia and their primary carers feel that the different activities are acceptable, that it is possible to deliver them in the community and that the way we measure the impact of the activities is not too difficult. The information we get will also help us plan a much larger study to gauge how effective the activities might be in helping people with memory problems/ dementia to live well with their dementia. It is not expected that people with memory problems/dementia and their carers will have any side effects from carrying out the different activities.

Where is the study run from?
National University of Ireland Galway, Ireland

When is the study starting and how long is it expected to run for?
The study commenced on 14th November 2016 and is due to end on 31st October 2020

Scientific title

The feasibility of a Comprehensive Resilience-building psychosocial Intervention (CREST) for people with dementia living at home in the community



Study hypothesis

To determine the feasibility of the CREST complex psychosocial intervention for people with dementia and their carers living in the community. Quantitative and qualitative feasibility assessment data will be collected to inform the decision to proceed with a future RCT and its optimal design

Ethics approval

CREST is a multi-level complex psychosocial intervention. All participants will receive the intervention. The intervention will run over 15 weeks and is comprised of various interrelated components targeting different participants and will include:
1) A 14-hour cognitive stimulation programme ‘Making a difference’ delivered over 7 weeks (1 hour twice a week), to people living with dementia
2) A 12-hour physical exercise programme, delivered over 8 weeks, (1 hour a week for 4 weeks and 2 hours a week for 4 weeks), by an exercise specialist to people living with dementia who will be supported by older people from the community
3) A dementia education programme which consists of three elements (a) a 1 hour one-off Community dementia awareness programme, delivered by trained dementia/community champions to members of the public (b) a 10 hour, educational programme delivered over 6 weeks, (1 hour 40 mins a week), by members of the research team to the carers of people with dementia (c) a 1.5 hour one-off continuing professional development (CPD) and accredited GP workshop delivered by a trained GP facilitator
