Vicious cycles of sleeplessness: A new scale for insomnia
Ytterligare information: Sleep, 26: Suppl., A298.
Worries about sleep, negative expectations of sleep, and frustration about sleep loss are assumed to play an important role in the development of insomnia. Eight items designed to measure aspects of vicious cycles of sleeplessness (VCS), on which insomnia patients and controls were found to differ in an earlier study, were used to form a new VCS scale. A sleep questionnaire including the VCS scale was sent to a randomly selected sample of 1400 subjects, aged 20–64 years. The response rate was 78.0%. The scale showed a one-factor structure, and had an adequate internal consistency. Women scored higher than men. Scores were significantly higher in a group of 263 subjects who complained of insomnia than in the others. The scores of subjects complaining of insomnia were fairly normally distributed. It is concluded that the VCS scale shows adequate reliability and is a possible tool for characterizing patients with insomnia. The next step is to administer the scale to a clinical sample, and also to let patients fill out the scale before and after treatment
