Insights
A novel parent-based intervention using the "Dream Changer" device significantly reduced childhood nightmares and sleep anxiety. These positive effects on children
Area of Science:
- Pediatric Sleep Medicine
- Child Psychology
- Behavioral Intervention
Background:
- Recurrent childhood nightmares can negatively impact children and their parents.
- Effective, accessible interventions are needed to address childhood nightmares.
Purpose of the Study:
- To evaluate the efficacy of a new parent-based intervention for childhood nightmares.
- To assess the impact of the "Dream Changer" device on nightmare frequency and sleep anxiety.
Main Methods:
- A randomized controlled trial involving 56 children (aged 3-10) and their parents.
- Intervention group received the "Dream Changer" device; control group was waitlisted.
- Parents completed online surveys assessing nightmare frequency, sleep anxiety, and daytime sleepiness.
Main Results:
- The "Dream Changer" intervention significantly reduced children's nightmare frequency (p = 0.001) and sleep anxiety (p = 0.006).
- Improvements were maintained at a 3-month follow-up.
- No significant effects were observed on children's sleep metrics or parental daytime sleepiness.
Conclusions:
- The "Dream Changer" intervention shows preliminary efficacy in reducing childhood nightmares and anxiety.
- This brief, accessible intervention offers a potential solution for affected families.
- Further research with larger samples and longer follow-ups is warranted.
Study Objectives:
Recurrent nightmares in childhood may have a range of detrimental effects for both the child and parents. This randomized controlled trial evaluated the efficacy of a novel parent-based intervention for childhood nightmares, using a new device called the "Dream Changer."
Methods:
A total of 56 children aged 3-10 years (M = 7.1 ± 2.1 years; 51.8% boys), and one of their parents were randomized to either the intervention or waitlist control group. The intervention group received a "Dream Changer"-a light-emitting remote-control-like device that the child was encouraged to take to bed and use upon experiencing a nightmare. Parents completed online surveys at baseline, 1-week, and 2-weeks following the intervention. Parents in the intervention group additionally completed a 3-month follow-up survey. Outcome variables included children's nightmare frequency, sleep-wake patterns, and sleep anxiety, as well as parents' daytime sleepiness.
Results:
Significant group-by-time interaction effects were found for nightmare frequency (p = 0.001) and sleep anxiety (p = 0.006). Parents of children who received the "Dream Changer" reported fewer nightmares (Mdifference = 1.7, p < 0.001, d = 1.06) and decreased anxiety (Mdifference = 0.9, p = 0.001, d =0.41) at post-intervention, whereas such benefits were not found in the waitlist control group. Three-month follow-up assessments demonstrated that gains were maintained over-time. Interaction effects were not significant for children's sleep metrics or for parents' daytime sleepiness.
Conclusions:
The present study provides preliminary evidence for the efficacy of a brief, highly accessible intervention for reducing children's nightmares and nighttime anxiety. Future research may wish to test these effects using larger samples and longer follow-up assessments.
Clinical Trial Registration:
The trial has been registered at the Australian New Zealand Clinical Trials Registry (https://www.anzctr.org.au/; Identifier:ACTRN12620000633987).
