Research and your data

At ieso, we believe that everyone should have access to effective mental healthcare, when and where they need it.

We want to make therapy as good as it can be – so that everyone receives the support that is right for them, first time.

We do this by providing types of therapy that already have a strong evidence base to show that they work. We then invest heavily in research to understand how to make therapy as effective as possible, for as many people as possible.

By analysing patterns in the aggregated, de-identified data from thousands of patients, our scientists and clinicians can learn how our patients’ treatment outcomes relate to the therapy they are given. This enables us to discover more about the causes of mental health conditions, and why different people respond better to different types of therapy. We use this information to make our existing products and services more effective, and to develop new ones.

We take data privacy extremely seriously. Mental health is deeply personal; we store patient data confidentially, protect it using the highest encryptions and security standards, and use it responsibly in accordance with local laws, regulations and standards. We have internal procedures in place to safeguard your privacy so that only the minimum necessary information is used to conduct the research on the most de-identified data possible, including anonymisation where possible.

Providers of NHS-funded mental health services in England are required to provide a specified set of data (Minimum Data Set) to NHS Digital, who use this to create a picture of services delivered around the country to check that quality standards are similar everywhere. Much of our research is based on this NHS Minimum data set, but we also use machine learning, natural language processing (NLP) and artificial intelligence (AI) on questionnaire data, typed communications between you and your therapist, and on therapist summaries of your treatment sessions.

We are committed to being transparent about how we collect, use, retain, share and protect patient data for treatment and research, so that you can understand the benefits and risks, and make informed choices about how your data is used.


It’s natural to have an interest in your treatment. People often want to know what we do, how it works and whether it will work for them. Here’s our take on some of the questions we often come across. If you don't see your question here, get in touch with us by submitting a question through our contact page here. We’ll be glad to help.


ieso is committed to delivering a high quality service. The views and experiences of the people that use our service are important to us and help us in the process of continuous quality improvement.
