SHUTi digital insomnia therapy outperforms online education in meta-analysis

A meta-analysis published in SLEEP assessed two decades of research on Sleep Healthy Using the Internet (SHUTi), a digital cognitive behavioral therapy for insomnia program. Investigators searched four databases through October 7, 2025, identifying 29 publications reporting unique data from 25 studies involving 14,166 participants. Outcomes included the Insomnia Severity Index (ISI), sleep onset latency, and wake after sleep onset, measured using sleep diaries.

Among participants provided SHUTi, average declines from baseline to follow-up were at least 8 ISI points, 21 minutes in sleep onset latency, and 27 minutes in wake after sleep onset excluding early morning awakening, or 35 minutes including it. Across 10 randomized controlled trials against online education, standardized mean differences favored SHUTi at post-assessment and six- and 12-month follow-ups: −1.03 to −0.85 for ISI, −0.41 to −0.32 for sleep onset latency, and −0.48 to −0.45 for wake after sleep onset. Overall, 64% completed a full therapeutic dose.

These findings support SHUTi as an insomnia treatment across diverse populations, with comparative benefits persisting through one year. However, the outcomes were participant-reported, and the baseline-to-follow-up declines should not be interpreted as treatment effects versus control. Only the abstract was available; details on risk of bias, heterogeneity, and funding could not be assessed.
