Parenting programs have been shown to be effective in preventing and reducing externalising problems in young children. Despite their efficacy, the low rate of initial parental engagement in these programs is a major challenge for clinicians and researchers. Few studies have examined factors associated with rates of initial engagement in parenting…

Young children are surrounded by ubiquitous environmental print (e.g. signs, product labels) on a daily basis in their homes and communities. Parent-child interactions with environmental print has the potential to foster emergent literacy. A randomised controlled pre-posttest study was conducted to examine the effects of a parent-child…

Executive functions (EFs) develop rapidly in preschoolers and lay an important foundation for school readiness. One potential method of supporting EF development is through mindfulness-based interventions (MBIs). Whereas studies with older children and adults have supported this approach, research with young children has been more limited. In the…

This paper presents evidence on the amount of classroom variation in gains across various domains of achievement within the Tennessee Voluntary Pre-Kindergarten (TN-VPK) program; the data are taken from the randomized control trial (RCT) design of the TN-VPK evaluation. This study explores areas where those differences are largest, and offers…

Secondhand smoke (SHS) is caused by burning tobacco products that emit up to 7000 chemicals and over 70 carcinogenic compounds. Thirdhand smoke (THS) is solid residue remaining on furniture and carpets, including suspended particles derived from a burned tobacco product. Exposure to these compounds occurs through inhalation, oral ingestion, or…

This study evaluated the efficacy of the Preschool First Step (PFS) to Success early intervention for children at risk for attention deficit hyperactivity disorder (ADHD). PFS is a targeted intervention for children 3-5 years old with externalizing behavior problems and addresses secondary prevention goals and objectives. As part of a larger…

Access to Head Start has been shown to improve children's preschool experiences and school readiness on selected factors through the end of 1st grade. Two more years of follow-up, through the end of 3rd grade, can now be examined to determine whether these effects continue into the middle elementary grades. The statistical design and impact…

The Nuffield Early Language Intervention is designed to improve the spoken language ability of children during the transition from nursery to primary school. It is targeted at children with relatively poor spoken language skills. Three sessions per week are delivered to groups of two to four children starting in the final term of nursery and…

Studies of small-scale "model" early-childhood programs show that high-quality preschool can have transformative effects on human capital and economic outcomes. Evidence on the Head Start program is more mixed. Inputs and practices vary widely across Head Start centers, however, and little is known about variation in effectiveness within…

The goals of the Head Start Impact Study (HSIS) are to: (1) determine the impacts of Head Start on children's school readiness and parental practices that support children's development; and (2) to determine under what circumstances Head Start achieves its greatest impacts and for which children (US Department of Health and Human Services, 2010).…
