Abstract [en]

The aim of this study was to investigate whether arousal, distress, and sleep-related beliefs are related to the development of insomnia. From a randomly selected sample of 3,600 individuals from the general population (50-60 year), 2,239 participants filled out a baseline and 1-year follow-up questionnaire. Logistic regression and cluster analysis were used to investigate whether the psychological mechanisms were related to the development of new cases of insomnia over one year and whether it was possible to classify the participants based on their profiles of psychological mechanisms. The results showed that arousal, sleep-related beliefs, and depression were significantly related to the development of new cases of insomnia (13% of the variance). High scores on all three mechanisms were characteristic of one cluster (18% new cases of insomnia) and low scores on the mechanisms of another cluster (5% new cases of insomnia). This study shows that arousal, sleep-related beliefs, and depression are associated with the development of insomnia, and that psychological mechanisms often co-occur in individuals who develop insomnia.
