Nytt ljus över dagbesvär vid insomni: spelar psykologiska processer en underskattad roll?

Sammanfattning: This study examined the psychological processes of autonomic arousal and distress, erroneous beliefs about sleep, worry about sleep, selective attention and monitoring and safety behaviours related to sleep, on the subject of daytime impairments associated with insomnia. The psychological processes were evaluated against as follows: sleep measures, anxiety, depression, medical disease and the use of medications. The measure daytime impairments complied with the established research diagnostic criteria. A correlation analysis indicated that psychological process, anxiety, depression and one of the sleep measures are associated with daytime impairments. The results of a multiple regression analysis proved that only erroneous beliefs about sleep, worry about sleep and safety behaviours related to sleep are linked to daytime impairments associated with insomnia. An influential mechanism taking part in the psychological processes appears to be catastrophic thinking concerning personal sleep. One crucial clinical conclusion is that treatments for daytime impairments associated with insomnia should focus more on the relevant psychological processes, rather than on the particular sleep difficulties.
