Description of intervention(s) / exposure
Insomnia patients living in or near the Tamworth area will be referred into the study by their GP. Alternatively, patients may see a poster/flyer in the GP waiting room and contact the study coordinator directly. A total of 24 eligible and willing patients will be randomly assigned to either the sleep intervention group (N=12) or the wait-list control group (N=12).
Participants assigned to the sleep intervention group will be invited to undertake a sleep intervention following the completion of their baseline questionnaires, with no waiting period. The sleep intervention is led by a trained Practice Nurse and it is an evidence based behavioural therapy sleep intervention with cognitive components. It consists of 4 x 1.5 hour individual sessions with each session taking place once a fortnight over a period of 7 weeks. Sessions 1: will provide the patient with information about sleep. Session 2: will provide the patient with information about clinically proven effective behavioural treatments for insomnia. These include Stimulus Control Therapy, Sleep Restriction Therapy, Paradoxical Intention and Sleep Hygiene. A discussion about what interventions are most likely to work for a particular patient will be addressed in this session. Session 3: will be about increasing patient awareness about their behaviours and thought patterns. Barriers preventing patients from starting or maintaining changes will be discussed and motivation and confidence levels will be explored. Session 4: will consolidate the information presented during the course. Future individual sleep plans for patients will be explored and discussed.

Comparator / control treatment
Participants randomly assigned to the wait-list control group will receive treatment as per usual as well as receive booklets containing written information on relaxation strategies and the relationship between mood and sleep. After 3 months has elapsed from the completion date of their baseline questionnaires, participants in the wait-list control group will be offered the same sleep intervention as the treatment group.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation Method: It will be done individually using a randomisation list prepared ahead of time. This will be done on a 1:1 ratio in terms of either being assigned to the Intervention group or the Wait List control group. It will be done using permuted blocks of varying size with allocation concealment achieved by sequentially number opaque sealed envelopes.

Summary
Brief summary
Insomnia is a common and distressing sleep disorder. Untreated insomnia is responsible for increasing health care utilisation through negatively impacting on mood (depression & anxiety), family and workplace behaviour which in turn increases a socioeconomic burden on the community (Ohayon 2002; Siebern & Manber 2010; Hilman et al., 2008). Cognitive Behavioural Therapy (CBT-i) is the most efficacious treatment for insomnia by enabling the individual to change current ineffective behaviours and challenge faulty beliefs about sleep (Morin et al., 2006). Effective behavioural sleep interventions include sleep restriction therapy (Edinger & Means, 2005) stimulus control therapy (Bootzin, 1972) paradoxical intention (Morin 1993) and sleep hygiene (Hauri, 1991). These behavioural sleep interventions have successful treatment outcomes when run by the equivalent of Practice Nurses in Scotland and do not require trained psychologists (Espie et al., 2001; Espie et al., 2007). Although CBTi has proven effectiveness, access to both sleep centres and professionals who are able to provide such services is limited in most major cities and is often absent in rural communities in Australia. More recently a “stepped care” model to treat insomnia has been proposed (Espie 2009). This model proposes a generic pyramid where the majority of patient care is undertaken at baseline with an evidence-based but less intense treatment intervention whilst “greater expertise” in both assessment and treatment is used towards the top step of the pyramid. This model has considerably validity in the treatment of insomnia patients using group CBTi which has an efficacious record in a number of different age groups and settings. For many rural families the cost of going to capital cities for an ongoing treatment intervention is not feasible. There are also the ongoing issues of social isolation and increased depression rates particularly in young men in rural communities. Treating insomnia symptoms is an effective first step to address these issues. Training Practice Nurses to undertake a predominantly Behavioural Therapy (BT) intervention will enable the provision of a treatment which is both easily accessible and has been shown to improve sleep and mood in most individuals. The primary aim of this project is to assess the outcomes of a BT intervention for insomnia when delivered by Nurse practitioners in a medical setting in rural NSW.
