Unguided digital insomnia therapy improved symptoms, with widely varying results
A review of randomized trials found lower insomnia and depression symptom scores after treatment, but large differences between studies complicate the overall picture.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Unguided digital cognitive behavioral therapy for insomnia reduced insomnia severity and depressive symptoms across the included trials. The pooled results describe symptom scores after treatment, while substantial variation between studies means the average cannot show how consistent the benefit was across programs or participants, or how long it lasted.
Results differed substantially across trials, and the abstract does not describe the comparison treatments or follow-up lengths. This abstract-based summary therefore cannot establish durability or which program would work best.
Symptoms were the outcomes
The review assessed insomnia severity and depressive symptoms. Improvements in these measures do not by themselves show remission, restored daily functioning or reduced need for other care; those outcomes are not reported here.
Averages conceal differences
Both web and app programs appeared in the analysis, but the abstract does not establish that either format is superior. Large differences among trial results remain central to interpreting the pooled findings.
