Insights
Sleep problems in young children experiencing maltreatment are linked to increased internalizing and externalizing behaviors. Napping, however, is associated with better social-emotional functioning, highlighting sleep
Area of Science:
- Child Psychology
- Developmental Psychology
- Sleep Science
Background:
- Sleep disturbances are common in young children exposed to maltreatment.
- Poor sleep quality may negatively impact social-emotional well-being in this vulnerable population.
- Reciprocal relationships between sleep and social-emotional functioning are suspected.
Purpose of the Study:
- To investigate the longitudinal associations between sleep problems and social-emotional functioning in infants and toddlers.
- To examine the impact of daily napping on social-emotional development in children from families involved with Child Protective Services (CPS).
Main Methods:
- Longitudinal study with 123 parent-child dyads referred to CPS for maltreatment.
- Data collected at baseline and 3, 6, and 9 months post-baseline.
- Parent-reported measures of child's social-emotional functioning (internalizing/externalizing behaviors, social competence) and sleep problems/napping.
Main Results:
- Higher baseline externalizing behavior predicted more sleep problems at 3 months.
- Sleep problems at 3 months were associated with increased internalizing and externalizing behaviors at 9 months.
- Napping at 3 months was linked to lower internalizing/externalizing behaviors and higher competence at 9 months.
Conclusions:
- Parental concerns about sleep problems longitudinally correlate with internalizing and externalizing behaviors in maltreated children.
- Children's napping behavior longitudinally associates with improved social-emotional outcomes, including reduced internalizing/externalizing behaviors and enhanced competence.
Objective/Background:
Insufficient and/or poor-quality sleep may contribute to poor social-emotional well-being, and vice versa, among young children who have experienced maltreatment. This study examined longitudinal associations between sleep and social-emotional functioning among a sample of infants and toddlers from families involved with Child Protective Services (CPS) for maltreatment.
Participants:
Participants were 123 parents and their infant or toddler (baseline age 10 to 24 months) from families referred to CPS for maltreatment.
Methods:
Data were collected at baseline and at 3, 6 and 9 months post-baseline. At all time points, parents completed a questionnaire about their child's social-emotional functioning including internalizing behavior, externalizing behavior, and competence in social-emotional skills and social relatedness. At 3 months post-baseline, parents reported about their child's sleep problems and daily napping behavior.
Results:
Higher baseline externalizing behavior was associated with a greater propensity for sleep problems at 3 months post-baseline. Sleep problems at 3 months post-baseline were associated with higher internalizing and higher externalizing behavior at 9 months post-baseline. Daily napping at 3 months post-baseline was associated with lower internalizing behavior, lower externalizing behavior, and higher competence at 9 months post-baseline.
Conclusions:
Among this sample of young children from families involved with CPS for maltreatment, parents' concerns about their child having a sleep problem longitudinally associated with children's internalizing and externalizing behavior. Children's daily napping behavior longitudinally associated with later internalizing behavior, externalizing behavior, and competence.
