Plain English Summary

Background and study aims
Volunteer Support involves a volunteer, such as a student or member of the community, spending time with a person living in the community with mental health difficulties. The volunteer and patient will meet every 2 weeks for a period of 6 months, and they will do joint social activities which they will decide on together. They can also meet with other pairs of patients and volunteers and spend time together as a group. This Volunteer Support aims to improve the patient’s social interactions and engagement with the community. This study aims to find out whether Volunteer Support can help to improve care for people living with severe mental illness in Bosnia and Herzegovina. More specifically, the researchers want to find out how patients and volunteers experience Volunteer Support when it is used on a regular basis. They also want to find out if Volunteer Support improves outcomes like quality of life and symptoms.

Who can participate?
Patients aged 18 and older with severe mental illness

What does the study involve?
All patients are randomly allocated into two groups: one group receives Volunteer Support and one group (the control) does not receive Volunteer Support (both groups receive their usual treatment). The two groups of patients are compared to see if Volunteer Support makes a difference to outcomes like quality of life and symptoms. Patients in the Volunteer Support group are also interviewed to see how they experienced the intervention.

What are the possible benefits and risks of participating?
For patients, they will be taking part in testing an intervention which might lead to improved quality of life, social functioning and symptoms. The study will benefit volunteers who take part in terms of the training and supervision they will receive to enable them to implement the intervention. For all participants involved in the study, their suggestions and experiences might be incorporated into further adaptations of Volunteer Support, so that it is tailored to the needs of patients, carers and clinicians in the context of the mental health care system in Bosnia and Herzegovina. Severe mental illnesses cause a high burden for societies with high levels of distress and high costs to individuals who are affected. This is particularly worse in low and middle-income countries such as Bosnia and Herzegovina, where there is a lack of human and financial resources for specialised mental health services in the community. The testing of Volunteer Support will provide evidence for interventions for people with severe mental illness in the community. It is unlikely that any significant ethical, legal or management issues will arise from this study, but some potential risks might be: within the research assessments and interviews that take place across both studies, questions will be raised with participants that might trigger feelings of distress or anxiety. Participants may experience anxiety in trying a new intervention. Throughout the intervention-testing period, individuals will continue to receive their routine care, including any medication, in addition to the test intervention. The intervention can be stopped at any point. The intervention to be tested (Volunteer Support) has an evidence base for effectiveness. There may be risks for volunteers who are supporting someone with mental illness, including the emotional burden and maintaining patient confidentiality. The researchers will minimise these potential risks by providing in-depth training to volunteers to help them understand what severe mental illness, how to manage the volunteer-patient relationship and how to keep in regular contact with the volunteer coordinator. There will be ongoing support and supervision for volunteers throughout the intervention period.

Study information

Scientific title

Testing the effectiveness, acceptability and feasibility of Volunteer Support in severe mental illness in Bosnia and Herzegovina: a randomised controlled trial


Study hypothesis

To test the acceptability, feasibility and effectiveness of Volunteer Support against usual treatment.
The specific research questions are :
1. How can Volunteer Support be used to support community mental health care in Bosnia and Herzegovina?
2. How is Volunteer Support experienced by patients and volunteers?
3. How do patient outcomes change when Volunteer Support is used?

Patients with severe mental illness (including psychosis)


72 patients will be recruited, and each patient will be randomly allocated to either a control or intervention group. Randomisation will be done by UK based research team using STATA statistical software and allocations communicated to the unmasked researchers in Bosnia team. Patients will be randomised to either the intervention or control groups so that each patient will either receive Volunteer Support OR receive their usual treatment.

Masking: randomisation will take place after recruitment of participants and completion of baseline assessments. Follow-up assessments at 6 and 12 months will be completed with participants by masked researchers. Measures are in-place to ensure that researchers completing follow-up research assessments remain masked to participant allocation.

Patients allocated to the intervention group will receive Volunteer Support delivered by a volunteer every 2 weeks. The intervention will be over 6 months during which patients will receive 6-7 Volunteer Support sessions. Volunteer Support is where a volunteer (such as a student or member of the community) spends time in the community with someone experiencing mental health difficulties. The focus of this intervention is joint social activities (e.g. walking in the park, playing sport) and each patient will be paired with one volunteer. There is flexibility for patient-volunteer pairs to spend time in groups with other patient-volunteer pairs.

Patients allocated to the control group will receive their usual treatment over the 6 month period.

Results and Publications

Publication and dissemination plan

The statistical analysis plan is being written and the trialists are planning publication(s) of a large protocol paper describing the work of their Research Group, including this study, and are considering writing more detailed protocol papers. They intend to publish the quantitative and qualitative findings from this study by August 2020. Regarding dissemination, this study is part of a research group which also aims to build sustainable research capacity. The dissemination plan therefore aims to inform research, policy and practice. The trialists plan to disseminate findings across Bosnia and Herzegovina and across the wider regional network of South Eastern Europe. Dissemination will include publications, attending conferences, and using platforms like Twitter and the Group website.

IPD sharing statement
The trialists will ensure that the study dataset is available for sharing on request following the publication of the main research papers. This is to ensure the scientific impact of the project is maximised. Prior to making the dataset available to interested individuals, the dataset will be pseudonymised and any potentially identifiable data removed. For publications that require data to be accessible, they will comply with this as guided by FAIR principles.
