The science behind our solution.
Deeply evidence based.
Behavioural science has been harnessed for over 50 years to design effective strategies to promote mental health and prevent problems such as depression and anxiety.
Our solution translates behavioural treatments into the real world. We combine psychological science with clinical epidemiology, data science and health economics.
The value of the Third Age Therapeutics solution has been tested in rigorous scientific experiments in the form of randomised controlled trials. This underpinning research was funded by the National Institute for Health and Care Research (NIHR) and featured in Forbes.
“These results are an important step forward in understanding what works in tackling and preventing loneliness and depression. The research is also a great example of how public money allows researchers, healthcare professionals and the public to work together across institutions and organisations to deliver results that will really make a difference to people’s health and wellbeing.”
