Notes from the review of this manuscript
This manuscript analyzes findings from the same randomized controlled trial as Bernard et al. (2012), and additional contextual information about the study is from this source. Information to establish baseline equivalence of the groups on socioeconomic status was based on correspondence with the author.

Study Participants
This randomized controlled trial (RCT) assigned parents to either ABC-Infant or a comparison home visiting program. Eligible families were those referred to Child Protective Services for risk of child maltreatment. At enrollment, children were younger than 2 years old. The follow-up was conducted when children were about 9 years old. The sample at follow-up included 100 children (44 in the ABC-Infant group and 56 in the comparison group). Characteristics of the ABC-Infant group (comparison group in parentheses) were as follows: 71 (68) percent of children were African American, 2 (13) percent were Caucasian, 21 (13) percent were biracial, 6 (6) percent were another race, and 21 (23) percent were Hispanic. Household income was less than $10,000 for 57 (66) percent of study families.
Setting
The study was conducted in a large mid-Atlantic city.
Intervention condition
Note: Navigate to the model page for more information about the home visiting model. See the source manuscript for more information about how the model was implemented in this study.
Comparison Conditions
Comparison families received Developmental Education for Families (DEF) in home visits that were the same duration (10 hour-long sessions) and frequency (weekly) as ABC-Infant. DEF was designed to enhance cognitive and linguistic development. For this study, the components related to promoting parental sensitivity or responsiveness were removed to distinguish it from ABC-Infant.
