Plain English Summary

Background and study aims
Acquired brain injury – injury caused to the brain by an event like an accident or infection – can have profound and life-changing consequences. Treatment typically focuses on rehabilitation – trying to recover as much function as possible in commonly-affected areas like mobility and thinking skills, and helping people compensate for long-term problems.
We have worked with patients to develop a new treatment that focuses on wellbeing by building opportunities for positive psychological experiences, positive health behaviours and social connectivity.

This project will test the feasibility of running a full-scale trial of our treatment and answer important questions about how best to run such a trial.

Who can participate?
Adults over 18 years, with acquired brain injury and psychological distress, living in the community.

What does the study involve?
Participants will be randomly assigned to either ‘treatment as usual’ or ‘group-based positive psychotherapy.’ The intervention consists of an eight-week group-based positive psychotherapy that has been developed by the researchers. The intervention will be delivered by clinical psychologists working in NHS brain injury services. Each session lasts 2.5 hours with activities to try at home between sessions. Several measures will be recorded at baseline, after the eight-week intervention and at 3 months follow-up.

What are the possible benefits and risks of participating?
The study will provide important information that is needed to establish if a full-scale study could take place. The intended benefits of this will be to increase wellbeing and decreasing psychological distress for people with an acquired brain injury, as well as giving a meaningful role to survivors of brain injuries.

A level of ‘psychological distress’ is an eligibility criteria for participation in the intervention, therefore some psychological distress may be experienced during the intervention, we have safety procedures in place to manage this. Acquired brain injuries can cause different types of cognitive problems, we have set out eligibility criteria relating to cognition so we can be reasonably sure the participants will be able to engage in the intervention. This also means we can avoid including participants that may be unable to engage in the intervention, which could potentially cause them psychological distress. Like in all studies, there is a risk of data breaches that could expose confidential information. We have managed this by not including personally identifiable participant information on our database, including data procedures for all staff to follow, and by setting a training standard for all staff involved in the study.

Public involvement
Our research is shaped by the feedback that we have received from brain-injury survivors. They have told us clearly what they want from healthcare providers. Our patients have been involved in developing the new treatment and planning this proposal. A key aspect of our treatment is the use of patient-mentors. Importantly, three service users are co-applicants on our application and all have experienced the intervention as participants and mentors. These individuals have individual skills that add considerable value to the intervention as well as the research team.

Scientific title

Group-based positive psychotherapy for people living with Acquired Brain Injury: A feasibility study



Study hypothesis

The methodological approach will be feasible to determine the clinical and cost-effectiveness of a novel positive psychology intervention in a future trial for people living with ABI compared to a ‘treatment as usual’ control group (TAU)

Acquired brain injury


Participants will be randomly assigned using an electronic database system, to either ‘treatment as usual’ or ‘group-based positive psychotherapy.’ The novel intervention consists of an eight week group-based positive psychotherapy that has been developed by the researchers. The intervention has been developed using the ‘GENIAL’ model of well-being. The intervention will be delivered by clinical psychologists working in NHS brain injury services. Each session last 2.5 hours with activities to try at home between sessions. Several measures will be recorded at baseline, after the eight week intervention and at 3 months follow-up.

Primary outcome measure

The primary outcome regarding feasibility will be assessed against the ACCEPT criteria for the trial. This includes recruitment across sites, recruitment rate, intervention compliance clinicians, interventions compliance participants, randomisation process, data collection from participants, attrition rates and differences between groups in serious adverse events (SAEs) measured using case report forms and patient records.

Secondary outcome measures

1. Psychological distress measured using the DASS-21 at time 1 (before the intervention), 2 (after the intervention), and 3 (follow-up at 3 months)
2. Well-being measured using the PERMA profiler at time 1, 2 and 3
3. General health and well-being using heart rate variability at time 1, 2 and 3
4. General capability measured using the ICECAP-A at time 1, 2 and 3
5. General health state and quality of life using the EQ-5D-5L at time 1, 2 and 3
6. Health care costs using the client service receipt inventory (CSRI) at time 1 and 3
7. Participant experience of recruitment, eligibility, consent and their experience of several aspects of the intervention (session context, length, homework, their experience of using the materials) will be explored using qualitative methods and analysis. This only applies to the participants who attended the positive psychotherapy group at time 2
