Collateral Child and Parent Effects of Function‑Based Behavioral Interventions for Sleep Problems in Children and Adolescents with Autism.

This study looked at whether helping children with autism sleep better also improved other areas. When 41 children with autism received sleep treatment, not only did their sleep improve, but they also showed better behavior and fewer autism symptoms. Parents also slept slightly better and felt less stressed. While these extra benefits were small, they were positive, showing that fixing sleep problems can help the whole family.

This study examined the broader effects of function-based behavioral sleep interventions on 41 children and adolescents with autism spectrum disorder. Beyond improving sleep problems, the interventions produced collateral benefits including reductions in children's internalizing and externalizing behaviors and autism symptom severity. Parents also experienced small improvements in their own sleep quality and stress levels, though relationship quality remained unchanged (possibly due to already high baseline scores). While the collateral benefits were generally small in magnitude, they were consistently positive, supporting the value of treating sleep problems in autism as it may have ripple effects across multiple domains of functioning for both children and families.

Function-based behavioral sleep interventions for autism may provide benefits beyond sleep improvement, including reduced behavioral problems and autism symptoms. Clinicians should consider sleep intervention as potentially impacting multiple domains. The family-wide benefits support treating sleep problems as a priority intervention area in autism care.

Study design and methodology are not clearly described in the abstract. Sample size appears modest (41 participants). The magnitude of collateral benefits was generally small. Baseline relationship quality scores were already high, potentially creating ceiling effects for improvement in this domain.

This study follows McLay et al., Journal of Autism and Developmental Disorders, (2020) to investigate whether the function-based behavioral sleep interventions received by 41 children and adolescents with autism spectrum disorder (ASD) produced collateral improvements in ASD severity, internalizing and externalizing symptoms and parent relationship quality, ratings of depression, anxiety and stress, and personal sleep quality. Concomitant with reduced sleep problem severity, improvements were found in children's internalizing and externalizing behavior and ASD symptom severity. Small improvements were also found in maternal sleep quality and parental stress. There was little change in parental relationship quality post-treatment, possibly reflecting high baseline scores.

Overall, collateral benefits were generally small but positive, consistent with the limited extant research, and underscore the importance of investigating collateral effects across a range of variables.
