The free app will help people monitor their own mood and will help detect signs that they are becoming depressed or anxious. If the app finds a person could benefit from help, it will point them towards local treatment services, often ones that they can access without first going to their doctor.
On a PhD programme funded by the Medical Research Council and the Economic and Social Research Council, the Mood Mate app collects data anonymously to analyse whether monitoring mood over time helps people seek treatment - contributing to crucial research which could help health authorities provide better treatments in the future.
The app is the brainchild of Alex Gyani, a researcher in the Department of Psychology at the University of Reading. Alex first had the idea to conduct a trial using an iPhone app in December last year. Since then, Alex has been working to develop the app with a team of programmers and developers at the University of Reading.
Alex said: "Having a randomized controlled trial built into an app that is available on the iTunes store is a fantastic way to conduct research and the more participants we can recruit, the more we will learn. That's why an app is such a great way to conduct a trial like this one.
"We hope it will enable us to find new ways to help people suffering from mental health problems in the UK get the psychological treatments that have been shown to work."
More people than ever are suffering from stress, anxiety and depression. National surveys have found that 1 in 6 people could be suffering from a common mental health disorder at any given time. But many people are not accessing treatment that has been shown, in clinical trials, to be effective.
The Mood Mate app is designed to help increase the number of people who access psychological therapies in the UK. The government has spent £400 million on its Improving Access to Psychological Therapies (IAPT) initiative since 2007, including training 6,000 new therapists in Cognitive Behavioural Therapy (CBT). These treatments work, with one study showing that more than half of patients recovered and stayed well.
But the NHS is not treating as many people as it budgeted for. Some GPs are not referring patients to mental health services and some patients do not disclose these issues to their GPs, preferring more informal routes. The Mood Mate app is designed to help people decide if they need help and give them the information they need to refer themselves to local mental health treatment services, rather than having to go through a GP.
Mood Mate is available to be downloaded free from iTunes now.
Alex Gyani said: "We're absolutely thrilled with the early success of Mood Mate on the iTunes store. I was confident that we had created a great app, but the massive early take-up just shows the huge demand that exists for alternative ways for people with mental health issues to find help.
"Not only can the users of Mood Mate find help, but they'll also be contributing to vital research into better ways to link people with psychological treatments that work."
