Plain English Summary

Background and study aims
DIALOG+ is an intervention delivered on a tablet or smartphone using an app. It is designed to help mental health professionals to improve the structure of their routine meetings with patients. It also helps to improve communication with patients during these meetings. Patients are first asked about how satisfied they are with eight areas of their lives (e.g. physical health, family relationships, leisure activities) and three areas of the treatment they are receiving (e.g. practical help, meetings), which is called the DIALOG scale. The patient then chooses up to three areas to discuss in more depth with their health professional. The clinician then discusses each area chosen by patients, using four steps that focus on solutions to the identified problems. This study aims to find out whether DIALOG+ can help to improve care for people living with severe mental illness in Uganda. More specifically, the researchers want to find out how patients and health professionals experience DIALOG+ when it is used during their routine meetings. They also want to find out if DIALOG+ improves outcomes like quality of life and symptoms.

Who can participate?
Patients aged 18-65 with severe mental illness (psychosis, bipolar disorder, psychotic/severe depression), epilepsy and/or substance misuse

What does the study involve?
All patients are randomly allocated into two groups. Patients in the DIALOG+ group use the app with their clinicians once per month for a period of 6 months. The other group (the control) do not receive DIALOG+ (both groups receive their usual treatment). The two groups of patients are compared to see if DIALOG+ makes a difference to outcomes like quality of life and symptoms. Patients in the DIALOG+ 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 also benefit clinicians 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 research, their suggestions and experiences might be incorporated into further adaptations of DIALOG+, so that it is tailored to the needs of patients, carers and clinicians in the context of the mental health care system in Uganda. 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 Uganda, where there is a lack of human and financial resources for specialised mental health services in the community. The testing of DIALOG+ 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 will 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 (DIALOG+) to be tested has an evidence base for effectiveness.

Study information

Scientific title

Testing the effectiveness, acceptability and feasibility of DIALOG+ in severe mental illness in Uganda: a randomised controlled trial


Study hypothesis

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

Mental, neurological and substance misuse disorders, which includes severe mental illness (psychosis, severe depression and anxiety), epilepsy and comorbid substance misuse


14 clinicians will be recruited. For each clinician, the research team will recruit 12 of their patients and then each clinician-patient cluster will be randomly allocated to active control or intervention group. Randomisation will be done by the UK based research team using STATA statistical software and communicated to the unmasked researchers in Uganda team. Clinician-patient clusters (12 patients per clinician) will be randomised to either the intervention or active control groups so that each clinicians will be either delivering DIALOG+ OR completing the DIALOG scale with their recruited patients.

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 and to minimise risk of contamination in clinicians allocated to the active control group. For example, masked researchers will not be based at the hospital where the research is taking place, and clinicians in the active control and intervention groups will be trained separately.

Patients allocated to the intervention group will receive DIALOG+ at their routine outpatient clinic appointments once per month. This will be delivered by their usual clinician using an app on a tablet computer. The intervention will be over 6 months during which patients will receive 6-7 DIALOG+ sessions. DIALOG + is a technology mediated intervention, which involves a structured patient assessment covering satisfaction with eight life domains and three treatment domains (DIALOG scale) and a four-step solution focused therapy approach to address patient concerns (+). DIALOG+ aims to make routine meetings between clinicians and patients therapeutically effective.

Patients allocated to the active control group will complete the DIALOG scale at their routine outpatient clinic appointments once per month. The scale is completed using an app on a tablet computer (therefore controlling for the use of the tablet).. This will take place over a 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. The trialists 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. They plan to disseminate findings across Uganda and across a broader, regional consortium, THRiVE, which operates across East and Central Africa, and which the PI in Uganda leads on. 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.
