Insights
Cognitive behavioral sleep interventions effectively reduce sleep onset latency in children and adolescents. While total sleep time showed no self-reported improvement, actigraphy indicated a slight increase, with benefits sustained at follow-up.
Area of Science:
- Pediatrics
- Sleep Medicine
- Behavioral Science
Background:
- Sleep problems are prevalent in children and adolescents, often exacerbating existing comorbid conditions.
- Effective interventions are crucial for improving pediatric sleep quality and overall health.
Purpose of the Study:
- To evaluate the efficacy of cognitive and behavioral sleep interventions in school-age children and adolescents.
- To analyze effects on total sleep time, sleep onset latency, wake after sleep onset, and daytime sleepiness.
Main Methods:
- Systematic literature search identifying six randomized controlled trials (n=528).
- Data extracted on sleep onset latency, total sleep time, wake after sleep onset, and daytime sleepiness using ratings and actigraphy.
- Analysis included immediate post-intervention and short-term follow-up data.
Main Results:
- Sleep onset latency significantly decreased with interventions, measured by both sleep diaries and actigraphy.
- Actigraphy showed a small but significant increase in total sleep time.
- No significant effects were observed for wake after sleep onset or daytime sleepiness immediately post-intervention.
- Follow-up data indicated sustained improvements in sleep onset latency and wake after sleep onset.
Conclusions:
- Cognitive and behavioral sleep interventions show promise for improving sleep in pediatric populations.
- Heterogeneity in treatment protocols and high risk of bias necessitate cautious interpretation of findings.
- Further large-scale, rigorous trials are required to confirm efficacy and refine interventions.
Study Objectives:
Sleep problems are common in children and adolescents and can aggravate comorbid disorders. This meta-analysis examined the effect of cognitive and behavioral sleep interventions (with four or more treatment sessions) from randomized controlled trials on school-age children and adolescents.
Methods:
In a systematic literature search, six randomized controlled trials were identified (n = 528; mean age = 14.6 years; female = 63%) that reported total sleep time (TST), sleep onset latency (SOL), wake after sleep onset, and daytime sleepiness from ratings and actigraphy.
Results:
After intervention, no effect was seen on self-reported TST, but when measured with actigraphy, an effect favoring the intervention group was observed (+11.47 minutes, P = .05). SOL decreased in the intervention group compared to the control group after intervention as measured by both sleep diaries (-9.31 minutes, P = .007) and actigraphy (-19.48 minutes, P < .0001). Effect sizes ranged from small to large. No effect was found for wake after sleep onset or daytime sleepiness. Short-term (4 to 8 weeks) follow-up data from four studies indicated maintained positive effects on SOL: sleep diaries -15.85 minutes (P = .01) and actigraphy -23.67 minutes (P < .0001). At follow-up, the effects on wake after sleep onset from ratings (-14.41 minutes, P = .001) and actigraphy (-7.54 minutes, P = .01) were significant, favoring the intervention group (moderate to large effect sizes). No effect on TST was indicated.
Conclusions:
Cognitive and behavioral sleep interventions are indicated to improve sleep in school-age children and adolescents. However, because treatment protocols were heterogeneous and risk of bias high, results should be interpreted with caution. Large and rigorous trials are needed.
