Research summary
It is estimated that 69% of common mental health problems include distress caused by sleep disturbance, yet such difficulties are rarely treated within primary care mental health services. However, specific group-based interventions for insomnia (Cognitive Behaviour Therapy for Insomnia, CBT-I) have been developed and evaluated; a recent meta-analysis of 23 studies (including data from 1379 participants) suggests that CBT-I should be offered in primary care (Johnson et al. 2016) as a group intervention.
The aim of the proposed research is therefore to conduct a pilot study to evaluate the acceptability and feasibility of implementing a single 2.5 hour evidence-based group workshop for insomnia (CBT-I) for clients of a primary mental health service. Clients of the service who have identified sleep difficulties as a problem will be offered a CBT-I intervention as part of their routine clinical care. These clients will be invited to participate in the research study to evaluate the acceptability and feasibility of the intervention, through a post-workshop review of their experience of the workshop and how well it met their needs. Participants will also complete a standardised assessment of sleep quality - the Insomnia Severity Inventory (ISI, Morin, 1993) before and after the workshop.
Although the ISI has been shown to be a very good measure of sleep quality, asking clients to complete the seven item scale does increase their treatment burden. We therefore also want to investigate whether it is possible to extract a 'Sleep Subscale' from a standard measure of mental health that clients already routinely receive. In order to do this, we need to analyse the fully anonymised data from a large number of clients who have already completed this measure (The Patient Health Questionnaire, PHQ9). We can then compare whether changes on the ISI are also reflected in the PHQ9 'Sleep Subscale'.
