Sleep Health among Children Adopted from Foster Care: The Moderating Effect of Parent-Child Sleep Interactions.

Objectives: Sleep disruption is prevalent among children placed in foster care, elevating risk for a range of deleterious outcomes. Theoretically, achieving permanency via adoption may have a positive influence on children's sleep via the presence of various factors, but little is known about the sleep health of children adopted from foster care, including predictors and moderators of sleep health.

Method: The current study included 226 parents who adopted a child from foster care in the U.S. (aged 4-11 years) within the past two years and a propensity score matched sample of 379 caregivers of children currently in foster care. Both samples completed online questionnaires about their child's sleep, physical, and mental health.

Results: Comparatively, children in foster care experienced more nightmares, night terrors, moving to someone else's' bed during the night, and worse overall sleep quality, whereas adopted children were reported to experience significantly more nighttime awakenings. In the adopted sample, a greater number of prior foster placements unexpectedly predicted lower total sleep disturbance scores, but this relationship was moderated by parent-child interactions around sleep. In general, greater parental involvement in children's sleep was associated with lower levels of child sleep disturbance.

Conclusions: Findings suggest that while specific sleep problems might remit after children in foster care achieve permanence, nighttime sleep fragmentation often persists. Parent-child interactions surrounding sleep may be pivotal in improving sleep health in this population.
