First of its kind digital therapeutic research identifies poor sleep as a target for improving depressive symptoms

The effects of the digital therapeutic Sleepio1 may extend to depressive symptoms, according to new research published today in the Journal of Sleep Research.
In the largest ever study examining the effects of a fully-automated digital sleep improvement program based on cognitive behavioural techniques (Sleepio) on insomnia and depressive symptoms, researchers found that use of Sleepio improved not only insomnia symptoms, but also depressive symptoms in individuals with insomnia and clinically significant depressive symptoms. Further analyses revealed a significant proportion of the improvements in depressive symptoms were caused by the improvements in sleep.*
The study included 3,352 participants and was a sub-analysis of data from two large effectiveness trials of Sleepio. The original trials investigated the effects of Sleepio on physical health and functioning and on mental health, respectively. In each case, study participants received digital cognitive behavioral techniques using Big Health’s Sleepio program.
The findings revealed that:
- Sleepio was associated with significant improvement not only in sleep, but also in mental health. Those using Sleepio experienced clinically meaningful and statistically significant reductions in depressive symptoms compared to the control group 8-10 weeks after intervention, with these effects maintained at 22-24 weeks after intervention
- Participants using Sleepio were almost 3 times more likely to no longer experience clinically significant depressive symptoms compared to control participants at post-intervention
- Improvements in sleep – as a result of using Sleepio – were responsible for causing 87 percent of the improvement in depressive symptoms
The findings of this latest research suggest that the effects of Sleepio are not limited to sleep and may also extend to improving co-occurring depressive symptoms. According to the researchers, addressing sleep problems in individuals with co-occurring depressive symptoms may increase the odds of depressive symptom resolution by a factor of 2.4 to 3 times.
Commenting on the findings, lead researcher and Research Manager at Big Health, Dr Alasdair Henry, said:
“Our study suggests that evidence-based digital therapeutics for sleep could be a powerful way to help millions of people not just sleep better, but also improve their depressive symptoms.
In clinical studies, Sleepio has repeatedly achieved statistically significant and clinically meaningful improvements in sleep and mental health. Our latest results indicate that Sleepio can be an effective way to help those experiencing insomnia and clinically significant depressive symptoms achieve better outcomes over the long term through evidence-based cognitive and behavioural techniques. ”
Professor of Clinical Psychology at the University of Oxford, Daniel Freeman, added:
“Depressive symptoms can be associated with significant stigma, which can prevent people from seeking help. These results show that addressing sleep may be an effective option for improving depressive symptoms, potentially providing a less stigmatized route to addressing broader mental health.
Digital programs like Sleepio overcome many of the barriers associated with accessing other forms of evidence-based care and it certainly increases people’s options. It could help in filling the enormous gap that currently exists in access to mental health care around the globe, and is particularly urgent during the current pandemic, when even access to routine care is disrupted.”
With this study publication, Sleepio is the subject of 40 published papers in the clinical literature, including 12 randomised controlled trials (RCTs).
