Notes from the review of this manuscript

In 2020, HomVEE updated this review to move child school attendance measures from the Positive Parenting Practices to the Child Development and School Readiness domain because ACF determined that HomVEE should place all school attendance and absence measures in that domain.

In addition to the randomized controlled trial, this study also reported findings from a matched comparison group design study. Outcomes from this comparison received a moderate rating when baseline equivalence was established on race/ethnicity, SES, and baseline measures of the outcomes. Several outcomes from this comparison received a low rating because the intervention and comparison groups were not equivalent on the cognitive pretest at baseline.

Study Participants

This study took place in two unnamed cities in Arkansas and New York. In Arkansas, families were recruited by word of mouth and with flyers. In New York, students were recruited through the city’s Public School Early Childhood Center. The participants in the two cities were quite different. In Arkansas, 93% of the participants were African American, 6% were white, 0% were Hispanic, 1% were another ethnicity, 42% received public assistance as their primary source of income, and 37% had not completed high school. In New York, 27% of the participants were African American, 24% were white, 30% were Hispanic, 19% were another ethnicity, 29% received public assistance as their primary source of income, and 26% had not completed high school.

Setting

The study was conducted in two unnamed cities, one in Arkansas and one in New York. The Arkansas city was relatively small and the school district served only 6,200 students, but the New York city has a population of 200,000 and is the fourth-largest in the state.

Comparison Conditions

Comparison families did not receive any of the HIPPY services. In the New York site, all study children were in preschool during the first study year and kindergarten during the second year. In the Arkansas site, the comparison children did not receive any preschool services. Most children at this site entered kindergarten in the second year of the study, but 8% were late kindergarten starters so were one year behind the other participants in formal schooling.
