The analysis improves upon prior research in several ways. First, longitudinal data was used from the Fragile Families and Child Wellbeing Study (FFCW), which has, to date, followed children from birth to age 9. The FFCW consists of a population-based sample of relatively disadvantaged urban families. Second, the associations of interest were examined by two statistical approaches. In a descriptive trajectory analysis, hierarchical linear modeling (HLM) was used to estimate associations of child maltreatment experiences with children’s initial levels of cognitive and social-emotional functioning at age 3, as well as with their developmental trajectories in these areas over the following 6-year
