Sleep therapy improved measured sleep outcomes after acquired brain injury
Randomized trials favored cognitive behavioral therapy for sleep disturbances after brain injury. Whether face-to-face and digital delivery differ remains uncertain.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Cognitive behavioral therapy improved pooled measures of sleep disturbance in people with acquired brain injury. Reported benefits included better perceived sleep quality and fewer insomnia symptoms. Both traditional and digital delivery showed improvements, but the absence of a statistically significant difference between them does not establish that the approaches work equally well.
The abstract omits participant totals, control conditions and follow-up duration. It describes CBT as safe without reporting adverse-event results, leaving safety and lasting benefit unclear.
What researchers found
Overall sleep disturbances
The -0.95 difference is in standard deviations, units based on how widely sleep scores vary. The negative value indicates fewer disturbances with CBT; comparator conditions and timing were unreported.
What improved
The review assessed overall sleep disturbance and separate sleep domains. Participants reported better sleep quality and fewer insomnia symptoms; the authors also reported improved objectively measured sleep efficiency. These outcomes do not establish brain-injury recovery.
Comparing delivery methods
The subgroup analysis did not detect a statistically significant difference between traditional and electronic CBT. This leaves uncertainty about their relative effects; it does not show that the delivery methods are equivalent.
