Insights
The KiSS program significantly improved pediatric insomnia, with most children no longer meeting diagnostic criteria one year post-treatment. This effective intervention for childhood insomnia showed stable results and high acceptance.
Area of Science:
- Pediatric Sleep Medicine
- Child Psychology
- Behavioral Therapy
Background:
- Insomnia is prevalent in school-aged children, frequently co-occurring with other mental health conditions.
- The KiSS program, a multicomponent intervention, was evaluated in a pediatric insomnia clinic.
- The study targeted an
- all-comer
- population, including children with comorbid disorders.
Purpose of the Study:
- To assess the effectiveness and acceptance of the six-session KiSS treatment for pediatric insomnia.
- To evaluate the long-term stability of treatment outcomes.
- To determine the program's suitability for children with comorbid mental health issues.
Main Methods:
- Forty-five families with children aged 5-10 years were randomized to either the KiSS intervention or a wait-list control group.
- The KiSS program integrated cognitive behavioral therapy for insomnia (CBT-I), hypnotherapy, and imagination techniques.
- Sleep diaries were used to track sleep efficiency (SE) and sleep-onset latency (SOL) before, immediately after, and 3, 6, and 12 months post-intervention.
Main Results:
- The KiSS intervention led to significant sleep improvements, with only 1.75% of treated children meeting insomnia criteria at 12 months.
- Sleep efficiency (SE) improved to 96%, and sleep-onset latency (SOL) decreased to 23 minutes, with normalized total sleep time.
- All observed sleep improvements were sustained for at least one year, and the program demonstrated high acceptance with zero dropouts during treatment.
Conclusions:
- The multimodal KiSS sleep training effectively improves sleep in children with insomnia, including those with comorbid mental disorders.
- The program's structure, with three sessions for parents and three for children, allows for easy implementation as a standalone or adjunctive therapy.
- Further research, including dismantling studies and trials with active control groups, is warranted.
Abstract:
Background: Insomnia is common in school-aged children and often associated with other mental disorders. Here, we investigated the effectiveness and acceptance of the KiSS program in an "all-comer" pediatric insomnia clinic. Participants/Methods: Forty-five families (children: 5-10 years, 57.8% female) were randomly assigned to the multicomponent six-session KiSS treatment (CBT-I, hypnotherapy, and imaginations) or a wait-list control group. A sleep diary was recorded before intervention or waiting time, immediately after, as well as 3, 6, and 12 months postintervention (primary outcome: sleep efficiency, SE; sleep-onset latency, SOL). Results: Sleep improved significantly after the KiSS intervention. Three to 12 months after the intervention, only 1.75% of treated children still met the diagnostic criteria for insomnia. SE improved to 96%, and both SOL (reduced to 23 min) and total sleep time were normalized. All improvements were stable for at least one year after the intervention. KiSS was well accepted (0% dropout during intervention) and well tolerated. Conclusions: Treatment with the multimodal sleep training KiSS leads to positive changes in the sleep of children with insomnia, including a subset of children that presented with comorbid mental disorders. With only three sessions for parents and three sessions for children, the treatment can be readily implemented as a stand-alone treatment or be combined with other interventions. Dismantling studies and studies with an active control group are ongoing.
