Abstract
Around one in three of the UK population suffer from sleep problems, resulting in high costs to society. Cognitive behaviour therapy for insomnia (CBT-I) has been shown to be effective. Community-based workshops may be a cost-effective way to provide CBT-I to groups that are usually hard to reach or reluctant to seek treatment. A sample of 151participants aged 18 or over from five London boroughs who self-referred were randomised into a group receiving workshops and a waiting list control group. 111 provided complete data on service use and outcome measures. Results from the cost-effectiveness and cost-utility analyses are presented using cost-effectiveness acceptability curves. At a maximum willingness to pay per quality-adjusted life-year (QALY) of £30,000, the probability of the intervention being cost-effective is 80%. If commissioners are willing to pay £150 per point improvement on the Insomnia Severity Index, which is approximately the cost of the intervention, there is a 97% probability of cost-effectiveness. Community-based CBT-I workshops are likely to be a cost-effective intervention to improve insomnia symptoms and are a promising low-level option to include within the panoply of interventions that are encouraged within the UK policy of increasing access to psychological therapies.
