Brief description Chronic insomnia is a prevalent health problem that affects 5-10% of the population. It is associated with significant physical and mental health problems as well as lowered quality of life. By far the most common treatment for insomnia continues to be sleeping tablets despite the problems of drug dependence, daytime impairment and long term loss of effect. It is also despite the evidence that behavioural therapies are more effective in the long term. In clinical experiments stimulus control therapy (SCT) is consistently the most effective of the behavioural therapies. However, SCT is difficult to carry out over the 4-6 week period necessary for effective treatment. If the treatment process could be shortened, it may increase the number of successful treatments. We have developed a laboratory procedure which includes the effective elements of SCT. These elements include sleep restriction and the experience of one rapid sleep onset each night. Our procedure involves some sleep deprivation and the experience of many (over 40) rapid sleep onsets over just one day. Therefore, it condenses 40 nights of the re-training benefits of SCT into just one day. A preliminary study has shown this procedure to be as effective as normal SCT. However, with no follow-up therapy to the procedure the initial gains tended to diminish with time. Our proposal is to test and extend the possible benefits of this new treatment procedure. We will compare it with the standard SCT as well as combine it with SCT. We feel that the greatest benefit may be to use the laboratory procedure as a kick start to SCT, which will by-pass the most difficult first 2--3 weeks of SCT. This will greatly reduce the time as well as absolutely improve the outcome. In further studies the laboratory procedure may be transferred to the patient s home, thereby further increasing its effectiveness. We feel the proposal will lead to a significant improvement in the non-drug treatment of insomnia.
