The Lighter Touch: Less-Restriction in Sequentially Implemented Behavioral Sleep Interventions for Children with Rare...

Area of Science:

• Pediatric Sleep Medicine
• Neurodevelopmental Disorders
• Behavioral Interventions

Background:

• Sleep difficulties are prevalent in children with rare genetic neurodevelopmental conditions (RGNC).
• Behavioral interventions are common for neurodevelopmental conditions but understudied in RGNC.
• Research is needed to identify effective and minimally restrictive interventions for this population.

Purpose of the Study:

• To investigate the effectiveness and acceptability of behavioral sleep interventions for children with RGNC.
• To determine the minimally sufficient components of behavioral sleep interventions.
• To apply a principle of least restriction in intervention sequencing.

Main Methods:

• A single-case multiple baseline design was employed.
• Eight children with RGNC (mean age 7.3 years) participated.
• Intervention components were sequentially administered based on the principle of less restriction.

Main Results:

• Significant improvements were observed in sleep onset latency (7/7 children), night wakings (6/7), and early morning waking/unwanted bed-sharing (3/3).
• Most improvements occurred during less restrictive intervention phases (circadian, antecedent, positive reinforcement).
• Five participants required modified extinction procedures; improvements were maintained at follow-up and interventions were parent-acceptable.

Conclusions:

• Function-based, less restrictive behavioral strategies are effective for treating sleep difficulties in children with RGNC.
• These strategies can be sufficient and should be implemented before more restrictive approaches.
• Prioritizing less restrictive interventions ensures effectiveness and parent acceptability.
