Cross-informant agreement between caregivers and teachers for prosocial behavior across child welfare settings.

Healthy social functioning has been a growing focus for understanding children's positive development and well-being. Despite the flexibility and cost-effectiveness of behavior rating scales, there has been a rising issue of concern in both practice and research applications regarding rating scales and its low cross-informant agreement. The present study aimed to analyze the extent to which caregivers and teachers agree about children's prosocial behaviors, identify whether there were differences in the degree of agreement across child welfare settings, and ultimately offer recommendations for assessing behavior for children involved with child welfare services. To do so, the reports of 1,224 children, caregivers, and teachers from the National Survey of Child and Adolescent Well-Being (NSCAW) I who have been investigated by Child Protective Services (CPS) for abuse and/or neglect have been examined. Intra-class correlation coefficients (ICCs) of caregiver and teacher assessment of children's prosocial functioning were calculated to understand the degree of agreement in their perceptions of children's prosocial behaviors. ICC values presented show that agreement was low but significant across all samples and subscales (ICC range, .11-.22). It is suggested that future researchers pursue examination of the underlying mechanisms or factors that contribute to informant discrepancies.

The relationship between diurnal cortisol slope and cognitive development among children maltreated as infants.

Little is known about the role of hypothalamic-pituitary-adrenal (HPA) axis functioning for children's cognitive development, especially among vulnerable groups. The current study explores the relationship between diurnal cortisol slope and cognitive outcomes among children at the ages of 5 and 6 who have been maltreated as infants and involved with child protective services, using data from the National Survey of Child and Adolescent Well-Being (NSCAW) I (N=158). Multiple regression analyses showed that a greater decline in salivary cortisol from morning to evening was positively associated with scores on applied problems and expressive communication, even after adjustment for confounding. It was also associated with lower odds of cognitive disability. There were null associations with letter-word identification, passage comprehension, auditory comprehension, matrices, and vocabulary. Results suggest that children involved with child protective services as infants, and thus exposed early to likely 'toxic' levels of stressors, may face dysregulation of the HPA axis and particular difficulties in some aspects of cognitive function. Potential explanations and implications for policy are discussed.
