Computerized cognitive behavioral therapy for insomnia reduces subjective overreporting of sleep onset latency in veterans with moderate-to-severe traumatic brain injury
In 36 veterans with insomnia and moderate-to-severe TBI, cCBT-I (SleepEZ program) decreased the discrepancy between subjective and objective sleep onset latency, driven by improvements in subjective but not objective sleep measures. Sleep efficiency discrepancies grew larger post-intervention due to subjective improvements without corresponding objective changes.

Computerized cognitive behavioral therapy for insomnia reduces subjective overreporting of sleep onset latency in veterans with moderate-to-severe traumatic brain injury The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 42/100 (low).
The Claim
Computerized cognitive behavioral therapy for insomnia reduces subjective overreporting of sleep onset latency in veterans with moderate-to-severe traumatic brain injury
This conclusion is most relevant to: United States veterans aged 18-60 years with current insomnia and a history of moderate-to-severe traumatic brain injury (N=36).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Changes in Subjective-Objective Sleep Discrepancies Among Participants With Post-acute Moderate-to-Severe Traumatic Brain Injury Following Computerized Cognitive Behavioral Therapy for Insomnia. (The Journal of head trauma rehabilitation, 2026) —
How It Works
The proposed biological pathway:
- ▸cCBT-I improves subjective sleep perception
- ▸Subjective sleep onset latency overreporting decreases
- ▸Objective sleep measures do not improve correspondingly
- ▸Result: Sleep efficiency discrepancy increases
Who Might Benefit
Evidence fit by population:
- ▸United States veterans aged 18-60 years with current insomnia and a history of moderate-to-severe traumatic brain injury (N=36)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Secondary analysis of intervention-arm data only, no control group comparison
- ▸Small sample size (N=36) limits generalizability
- ▸Actigraphy collected only during initial and final weeks, not throughout entire intervention
Frequently Asked Questions
What is the SleepEZ program?▼
SleepEZ is an online, primarily self-guided computerized cognitive behavioral therapy for insomnia program, with adjunctive assistance from a study clinician.
Did cCBT-I improve objective sleep measures in TBI patients?▼
No, objective sleep measures (actigraphy) did not show corresponding improvements, leading to larger discrepancies in sleep efficiency.
What sleep parameters showed the largest discrepancies at baseline?▼
At baseline, participants overreported sleep onset latency and early morning awakening, but greatly underreported waking after sleep onset, resulting in higher total sleep time on diaries compared to actigraphy.
Why is concurrent use of subjective and objective measures recommended?▼
Because subjective and objective sleep measures often disagree; using both provides a more complete picture of sleep health, especially after moderate-to-severe TBI.
