Plain English summary of protocol
Background and study aims
Following a stroke, around one third of people will have aphasia. This is a language disability that affects speaking, understanding, reading, and writing. We want to test a new therapy for people living with aphasia that targets language recovery, confidence, and emotional wellbeing. We have had excellent results in our university clinic. Now we want to see if it will work well in NHS settings, and what kind of support and training is necessary to deliver it.
Loss of language can be devastating: aphasia has been described as ‘identity theft’, and it is common that people with aphasia become depressed, anxious and isolated. People with aphasia want treatment to focus on improving both language and emotional wellbeing, yet they describe struggling to access mental health support due to their language difficulties. Further, once home they often receive limited language therapy, yet language therapy is most effective when people receive at least 20 hours.
We have developed a new therapy for language recovery and emotional wellbeing through running a series of workshops with five people with aphasia, three family members and four Speech and Language Therapists. We also met with experts in psychological therapy. We then trialled the new therapy in our university clinic with eight people with aphasia. We found that people improved in how confident they felt talking in different situations and made significant progress with their own personal goals (e.g., feeling at peace, ordering in a cafe). All participants were highly positive about combining psychological and language therapies within a single treatment.
Who can participate?
Adults who have aphasia as a result of a stroke can take part in the study. Participants need to be able to give informed consent and be willing to take part in therapy sessions and assessments.
What does the study involve?
Phase One: we will develop training packages, including online resources and support. We want to explore what training and support will help therapists in the NHS deliver the new therapy.
Phase Two: we will recruit 42 people with aphasia: half of them will receive the new therapy; half of them will receive standard care. The therapy is up to 23 therapy sessions spaced across 7 to 12 weeks, with some sessions delivered by experienced Speech and Language Therapists, and some by students or rehabilitation assistants who will be given careful support.
We will interview people with aphasia, family members and therapists about their experiences. We will also assess participants’ confidence communicating, language, quality of life and emotional wellbeing. We will assess everyone when they start in the study, and then 3 and 6 months later.
What are the possible benefits and risks of participating?
Participants may enjoy taking part. They may find it interesting to talk about their stroke and their life in the research visits. It may help other people with aphasia in the future. There are no medical risks or dangers to taking part. Participants will still receive normal NHS care. The main disadvantage to taking part is that participants will give up some time.

| Scientific title | EmotionaL and Language recovery in Aphasia (ELLA): a feasibility study developing a novel intervention for people living with post-stroke aphasia |
| Study acronym | ELLA |
| Study objectives | 1. Feasibility of developing and delivering a training package, resources and support that enable delivery of ELLA within NHS services 2. Acceptability of ELLA to people with aphasia, family members, and clinicians when delivered in NHS community services and perceived mechanisms of change 3. Feasibility of delivering ELLA within NHS community services, including barriers and facilitators 4. Feasibility and acceptability of study processes including recruitment and retention of participants, treatment fidelity, and documentation of usual care 5. Feasibility of conducting a future definitive RCT investigating clinical and cost effectiveness; determining primary outcome measure and sample size of future definitive trial |

| Intervention | There are two stages to the ELLA study. Phase one (months 1 to 11) is the preparatory stage, including developing training and resources. Phase two (months 12 to 27) is a feasibility randomised controlled trial. We will recruit 42 participants living with post-stroke aphasia from 6 to 8 community NHS services. Participants will be randomly allocated to either the ELLA intervention or treatment as usual. The intervention will be up to 23 ELLA therapy sessions spaced over 7 to 12 weeks. The therapy has been designed to be delivered by an experienced Speech and Language Therapist, with some sessions optionally delegated to be delivered by either student Speech and Language Therapists or rehabilitation assistants, under the oversight of the experienced therapist. The therapy targets language and emotional recovery, integrating evidence-based interventions. ELLA will be instead of equivalent language therapy, but in addition to all other usual NHS care. It can be delivered in person or online. Participants allocated to the control arm will receive standard NHS Speech and Language Therapy plus all other usual care. Outcomes will be communicative participation, mood, language, and quality of life. Participants will be randomised to either intervention or control. Participants with aphasia will be assessed at baseline (prior to receiving the intervention), 3 months, and 6 months post-randomisation. Participants with aphasia will be supported through collecting outcome measures in face-to-face interviews, by an experienced Speech and Language Therapist or other clinician with specialist training in facilitating the communication of people with aphasia. They will be able to select whether they wish to see the researcher in person (for example, in their own home) or online. A purposive sample of participants with aphasia, significant others, therapists, and student or assistant therapists will be invited to take part in in-depth interviews. We are interested in how people experience the intervention. Interviews will take place at the venue of the participant's choice (for example, their own home or online). Therapists will also complete brief questionnaires about their experiences of receiving the training, and pre- and post-study questionnaires exploring their experience of work and delivering therapy. |
| Intervention type | Behavioural |
| Primary outcome measure | Feasibility outcomes. Outcomes 1- 4 will be calculated using numbers presented in the CONSORT diagram; progression will be assessed using the traffic light criteria. 1. Proportion eligible/ screened measured using screening logs at the end of the 6 months recruitment period, ≥30% progress; 20-29% amend; <20% stop 2. Proportion who consent/ screened measured using consent forms at the end of the 6 months recruitment period, ≥60% progress; 40-59% amend; <40% stop 3. Recruitment over the course of the study measured using monthly consent rate over the 6-month recruitment period, ≥32 progress; 20-32 amend; <20 stop 4. Retention at 6 months post randomisation measured using follow up numbers of participants completing 6-month assessment (those who have not withdrawn or are lost to follow up), ≥80% or greater progress; 64-79% amend; <64% stop 5. Proportion who adhere measured using therapy logs to determine if participants have received at least 12 sessions at the end of the treatment period, ≥60% progress; 49-59% amend; <49% stop |
| Secondary outcome measures | 1. Communicative participation - measured using the Communicative Participation Item Bank at baseline, 3 and 6 months 2. Psychological distress - measured using the General Health Questionnaire - 12 item version at baseline, 3 months and 6 months 3.

| IPD sharing plan | The datasets generated during and/or analysed during the current study will be stored in a publically available repository. We anticipate we will store them on figshare. This will be fully anonymised data, shared after publication of the results of the study. We do not intend to share qualitative data, as we believe this has the potential to identify participants, and may change the dynamic of qualitative interviews. |
