Background: Little is known about the nature, range and prevalence of different subgroups in language trajectories extant in a population from 4 to 11 years. This hinders strategic targeting and design of interventions, particularly targeting those whose difficulties will likely persist. Methods: Children's language abilities from 4 to 11 years…

The Early Head Start evaluation included 17 sites drawn from the first two waves of programs started more than a decade ago. By design, the Administration on Children, Youth and Families (ACYF) selected programs that would reflect the range of service options and context of all extant program rather than choosing a representative sample. The sites…

Proximal environmental variables illustrate aspects of the environment that are experienced directly and specifically by the child. The current study examined the associations between three proximal environmental variables: (1) quality of the home environment, (2) regularity of family routines and (3) frequency of parenting daily hassles and…

This article describes a case study in the use of the Family Check-Up (FCU), a family-based and ecological preventive intervention for children at risk for problem behavior. The FCU is an assessment-driven intervention that utilizes a health maintenance model; emphasizes motivation for change; and offers an adaptive, tailored approach to…

The authors examined the longitudinal effects of the Family Check-Up (FCU) on parents' positive behavior support and children's school readiness competencies in early childhood. It was hypothesized that the FCU would promote language skills and inhibitory control in children at risk for behavior problems as an indirect outcome associated with…

Background: Five DNA markers (single-nucleotide polymorphisms, SNPs) have recently been found to be associated with general cognitive ability "g") in a sample of 7414 7-year-old twins. These children have also been studied at 2, 3, 4, and 7 years of age on measures of cognitive and language development and behaviour problems; family environment…
