Plain English Summary

Background and study aims
DIALOG+ is an intervention delivered on a tablet 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 life (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 the patient, using a four-step approach that focuses 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 Argentina. 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?
Any patient receiving care at one of the study sites who has a primary diagnosis of severe mental illness and who is aged 18-65

What does the study involve?
Patients use the DIALOG+ App within their routine clinical appointments once per month for a period of 6 months. This is delivered by their usual clinician using an app on a tablet computer. The intervention is over 6 months during which patients receive 6-7 DIALOG+ sessions. The researchers also interview patients and clinicians who have used DIALOG+ to see how they experienced the intervention.

What are the possible benefits and risks of participating?
Severe mental illnesses cause high levels of distress to affected individuals. In countries such as Argentina there is often a lack of human and financial resources for specialised mental health services in the community. This study will provide evidence on how to include effective and long-lasting local-based interventions for community based mental health programs in the country. Overall, the study will build both mental health and research capacity within Argentina. Additionally, for patients who will be involved in testing the intervention, this might lead to improved quality of life and symptom reduction. Mental health professionals will also benefit in terms of the training and supervision they will receive to enable them to implement the intervention.
The researchers do not predict any significant risks from participating in this study; however, it is possible that whilst completing the research assessment or qualitative interviews, the questions asked might trigger feelings of distress or anxiety. To minimise this risk, researchers with experience working with people with severe mental illness were employed. Additionally, research assessments can be stopped at any point, and further support can be provided to the participant if necessary. Participants might also experience anxiety in trying new interventions. Through the intervention-testing period, individuals will continue to receive their routine care, including any medication. The intervention can be stopped at any point.

Patients with severe mental illness (including psychosis, bipolar disorder and severe depression)


At least 5 clinicians and 40 patients will be recruited. Patients will receive DIALOG+ at their routine clinical 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+). DIALOG+ aims to make routine meetings between clinicians and patients therapeutically effective.

Results and Publications

Publication and dissemination plan

The researchers intend to publish the quantitative and qualitative findings from this study by March 2021. 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 researchers plan to disseminate findings across Argentina. Dissemination will include publications, attending conferences, and using platforms like Twitter and the group website.

IPD sharing statement
The datasets will be held at QMUL in anonymised form. Data sharing with external interests will be considered only after the publication of the findings that reflect the given data. The datasets will be available upon request from Stefan Priebe ( The data collected will be both quantitative and qualitative. The duration of availability of data has not yet been decided. During the course of the study, data will be shared internally between the research group using an online data collection platform called REDCap. The method for sharing the data externally (if required) will be decided in due course.
Informed consent will be obtained from all participants involved in the study. All participants are assigned a patient ID at the point of enrollment and all subsequent data collected will be linked to this ID, without any link to identifiable data following Good Clinical Practice.
