The Parents as Teachers (PAT) program is a parent-education program that in
cludes home visiting and is designed to begin prenatally or at birth. Throu
gh home visits, vis itors called parent educators help parents to strengthe
n their parenting skills and knowledge of child development and to prepare
young children for school. This article describes the PAT program and repor
ts the results of evaluations of two randomized trials of PAT: (1) die Nort
hern California (Salinas Valley) Parents as Teachers Demonstration, which s
ewed primarily Latino parents in the Salinas Valley of California's Montere
y County, and (2) the Teen Parents as Teachers Demonstration, which served
adolescent parents in four counties in Southern California.
The two, evaluations revealed small and inconsistent positive effects on pa
rent knowledge attitudes, and behavior, and no gains in child development o
r health, when anal! ses compared the experimental and control groups overa
ll. However, subgroup analyses in the Salinas Valley program indicated that
children in primarily Spanish-speaking: Latino families benefitted more th
an either non-Latino or English-speaking Latino families, with significant
gains in cognitive, communication, social, and self-help development. Subgr
oup analyses in the Teen PST Demonstration indicated that families that rec
eived both PST servicer, and comprehensive case management services designe
d to help mothers improve their life course benefitted most. Subgroup analy
ses in the Salinas Valley study suggested that children in families that re
ceived more intensive services benefitted more than children whose families
received less intensive services. Results from that study suggested that h
ome visits produced about a one-month developmental advantage per 10 visits
for participating children.
