Treating insomnia with online cognitive behavioural therapy (CBT) could reduce mental health problems such as anxiety, depression, and paranoia, according to a large randomised controlled trial published in The Lancet Psychiatry.

The Wellcome-funded study, co-authored by Professor Terry Brugha from our Department of Health Sciences (pictured), was conducted by researchers at the Sleep and Circadian Neuroscience Institute, University of Oxford. It found that sleep disruption is a driving factor in the occurrence of paranoia, hallucinatory experiences, and other mental health problems in young adults (university students) with an average age of 25.

The researchers aimed to improve sleep in these individuals in order to determine the effect on mental health problems such as paranoia (excessive mistrust), anxiety, and depression. 3,755 university students across the UK were randomised into two groups. One group received online cognitive behaviour therapy (CBT) for insomnia; the other group did not but had access to standard treatments.

Individuals who received the CBT sleep treatment showed large reductions in insomnia, as well as small, sustained reductions in paranoia and hallucinatory experiences. The treatment also led to improvements in depression, anxiety, nightmares, psychological well-being, and daytime work and home functioning. Those who received CBT were also less likely over the course of the trial to experience a depressive episode or an anxiety disorder. The research suggests that understanding and treating disrupted sleep could provide a key route for improving mental health.

The University also facilitated student volunteer access to the trial.
