The object of this study is to determine variables associated with therapy-success of a cognitive behavioral self help intervention for insomnia. In this study all participants receive an online self-help CBT manual consisting of information (psycho-education) about sleep and cognitive-behavioural exercises. Adult persons with insomnia will be invited via a popular scientific website to fill out online questionnaires. Participants will be measured 4, 16, and 40 weeks after intervention with the same questionnaires.

| Cognitive Behavioral Treatment | Behavioral | The techniques used throughout the self-help manual are all effective in reducing insomnia: 1) Stimulus control: patients should only go to bed when sleepy, use the bed and bedroom for sleep (and sex) only, maintain a regular rising time, avoid daytime naps and get out of bed and go into another room when unable to fall asleep within 15-20 minutes (return only when sleepy). 2) progressive muscle relaxation. 3) sleep hygiene education (improving health and environmental factors that affect sleep). 3). Sleep restriction, whereby participants will stay only the time in bed that they sleep. 4) cognitive therapy to challenge and dispute incorrect and unhelpful thoughts about sleep (e.g. I must sleep at least 8 hours, otherwise I'll be a wreck tomorrow). |
