Insomnia therapy improved remission across delivery formats, with differences in completion
A review of randomized trials found higher remission odds with individual, group and online therapy. Completion was higher with individual therapy than with the online formats.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Cognitive behavioral therapy for insomnia was associated with higher remission odds across every delivery format examined. Individual and supported online formats also showed higher remission odds than fully automated online therapy in an adjusted analysis. However, that comparison came from meta-regression, while lower completion remained a challenge for the online formats.
This abstract-based summary cannot assess an individual's likely benefit: follow-up periods, control details and confidence intervals are not reported. The adjusted comparisons across formats do not establish that delivery method alone explains the differences.
What researchers found
Insomnia remission across delivery formats
Each therapy format versus control groups; odds-ratio analyses. Assessment timing was not reported.
What counted as therapy
The therapy had to include both sleep restriction and stimulus control to qualify for this review. The authors distinguished supported online programs from fully automated ones, alongside individual and group treatment.
Completion answers another question
Researchers assessed remission and whether participants finished every session. Individual therapy had higher completion than either online format, highlighting that symptom outcomes and treatment participation answer different questions about how a program performs.
