This study examined associations between maltreatment and early developmental vulnerabilities in a population sample of 68,459 children (M = 5.62 years, SD = .37) drawn from the Australian state of New South Wales, using linked administrative data for the children and their parents (collected 2001-2009). Associations were estimated between (a) any maltreatment, (b) the number of maltreatment types, and (c) the timing of first reported maltreatment and vulnerability and risk status on multiple developmental domains (i.e., physical, social, emotional, cognitive, and communication). Pervasive associations were revealed between maltreatment and all developmental domains; children exposed to two or more maltreatment types, and with first maltreatment reported after 3 years of age, showed greater likelihood of vulnerability on multiple domains, relative to nonmaltreated children.
This article examines the relationship between preschool quality and children's early development in a sample of over 7,900 children enrolled in 578 preschools in rural Indonesia. Quality was measured by: (1) classroom observations using the Early Childhood Environment Rating Scale-Revised (ECERS-R), (2) teacher characteristics, and (3) structural characteristics of preschools. Children's development was measured using the Early Development Instrument (EDI). The article proposes two methodological improvements to preschool quality studies. First, an instrumental variable approach is used to correct for measurement error. Second, ECERS-R is adjusted to the local context by contrasting items with Indonesia's national preschool standards. Results show that observed classroom quality is a significant and meaningful positive predictor of children's development once models correct for measurement error and apply a locally-adapted measure of classroom quality. In contrast, teacher characteristics and structural characteristics are not significant predictors of child development, while holding observed classroom quality constant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
