This paper describes the Parent Child Development Center (PCDC) model and related experimental programs at Birmingham, Houston and New Orleans and summarizes findings from data gathered during the first five years of program operation. Preliminary findings from data collected after 1975 are also reported. All PCDC programs share several common features which define the PCDC approach to parent education. PCDCs must actively engage low-income families with young children between the ages of birth and three years. They are multidimensional programs providing a range of information and experiences to parents on children's development, child-rearing techniques, health, nutrition, home management, adult skills in relating to organizations and institutions and community resource utilization, while offering social activities and social and health services. Established in 1970 by the Federal Government to help mothers raise socially and cognitively competent children, PCDCs were found to have positive short-term outcomes related to child corpetence. Preliminary analyses of data collected since 1975 at the Birmingham and New Orleans sites show that mean Stanford-Binet IQs in program and control groups were nearly identical by the time participating children reached 60 months of age. At both sites, IQ effects at the time of program graduation appeared to be weaker for later cohorts, but the cohort across group interactions were not significant. (Author/RH)
