Mental Health App Can Protect Vulnerable Young People Against Depression: Study Finds - Video

A cognitive behavioural therapy (CBT) app has been found to significantly prevent increases in depression in young people who are at high risk - and could be implemented as a cost-effective public mental health measure.

Globally, concern is growing about the high and steadily increasing rates of anxiety and depression in young people. Effective and scalable ways of preventing poor mental health in this group are needed, and digital tools such as mobile apps have been proposed as part of the solution.

Whilst there is emerging evidence for mental health apps being effective in treating anxiety and depression, this project led by the University of Exeter is the first to rigorously test a mental health app on such a large scale across four countries. Two linked papers published in Lancet Digital Health report the results of the ECoWeB-PREVENT and ECoWeB-PROMOTE trials, which ran concurrently in the four-year study funded by Horizon 2020. Critically, these studies found that a CBT self-help app can protect vulnerable young people against depression.

In one of the largest studies of its kind, 3,700 young people took part across the UK, Germany, Belgium, and Spain and were allocated into two trials based on their emotional competence abilities at the start of the study. That resulted in 1,200 young people with reduced emotional competency scores that confer increased risk for depression such as increased worry and overthinking going into one trial focused on prevention, whilst 2,500 without such risk went into the other trial focused on wellbeing promotion.

Those two groups were then randomised in equal numbers to three different apps developed by the study. There was a self-monitoring app where people can report their emotions every day, a self-help app that provided personalised training in emotional competence skills, and a self-help app based on CBT principles. Participants were then followed up at three months and 12 months to see how their wellbeing and depression symptoms changed.

The trials found the CBT app prevented an increase in depression, relative to self-monitoring in the higher risk sample, but that there was no difference between any of the interventions in their effects for the lower risk sample.
