The purpose of this study was to examine parenting types in a low-income sample from a person-oriented approach. Data were used from a public use data set from the Early Head Start Research and Evaluation Project (EHSREP) along with new extant ratings of parenting behavior from the EHSREP archive of videotaped parent-child observations. Parenting behavior indicators were examined using latent class analysis as a grouping strategy across three time points to characterize this sample of 2631 Early Head Start mothers. Three latent classes of mothers were identified at 14, 24, and 36 months: developmentally supportive (the largest group in this sample), unsupportive, and negative. Predictors of parenting types were also examined and parenting types were linked to child outcomes. The results of these analyses show common characteristics of these distinct types of parents likely to be in Early Head Start programs and may help programs identify which families would most benefit from services to help them increase behaviors to promote their young children's early development.
