Effekt av digital CBTi på insomni, arbeids og daglig aktivitetsnivå
Kognitiv atferdsterapi for insomni (CBT-i) er en veletablert behandling av insomni, men få studier har undersøkt påvirkningen av digital CBTi (dCBTi) på arbeids og daglig aktivitetsnivå. Forskere fra NTNU, Folkehelseinstituttet, St. Olavs hospital og Newcastle University har i denne studien, med 1721 deltagere diagnostisert med insomni, undersøkt om CBTi hadde bedre effekt på arbeids og daglig aktivitetsnivå enn tradisjonelle søvnhygieneråd. Resultatene i studien viste at dCBTi var en effektiv behandling for insomni, og hadde positiv effekt på arbeids og daglig aktivitetsnivå, og støtter behovet for økt tilgang til dCBTi.

Study objectives: Cognitive behavioral therapy for insomnia (CBT-I) is a well-established treatment for insomnia, but few studies have explored its impact on work and activity impairment.
Methods: Data stem from 1721 participants enrolled in a randomized controlled trial comparing the efficacy of digital CBT-I compared with Patient Education. Baseline and 6-month follow-up assessments included self-reported ratings of presenteeism and general impairment (Work Productivity and Activity Impairment Questionnaire), and absenteeism (hours of missed work) and employment status. Insomnia was measured using the Insomnia Severity Index (ISI). Mediation analyses were conducted for each outcome with ISI scores at baseline and 9-week follow-up as the mediator. The analyses were adjusted for potential confounders (e.g., sex, age, comorbidities).
Results: dCBT-I was found to be associated with reduced activity impairment compared with PE (by 5.6%) but not presenteeism, absenteeism, or changes in employment status. Mediation analysis showed that changes in insomnia severity largely mediated improvements in presenteeism (by 5.4%) and activity impairment (by 5.5%). There were no significant mediational effects on absenteeism or employment status.
Conclusions: This study shows that dCBT-I is not only effective in improving insomnia. But also demonstrates positive effects on work and daily activities in general, supporting the need for increased access to dCBT-I.
