Notes

This manuscript analyzes findings from the same randomized controlled trial as Bernard et al. (2012). Additional contextual information about the study and to determine attrition is from Bernard et al. (2012) and based on correspondence with the author.

Study Participants

This randomized controlled trial (RCT) assigned eligible families to either ABC-Infant or a comparison home visiting program. Eligible families were participants in a foster care diversion program with children younger than 2 years who were referred to the program from Child Protective Services for various issues placing children at risk (for example, domestic violence, parental substance use, homelessness, or neglect). A total of 105 mother-child dyads were included in the study at follow-up (50 in the ABC-Infant group and 55 in the comparison group). In the ABC-Infant group, 64 percent of children were African American, 12 percent were Caucasian, 24 percent were biracial, and 20 percent were Latino. The majority (56 percent) of households reported an annual income of less than $10,000.

Setting

The study was conducted in a large mid-Atlantic city.

Home Visiting Services

ABC-Infant consisted of 10 weekly hour-long home visits. The sessions focused on five topic areas: providing nurturance, following the child’s lead, refraining from frightening behavior, parents recognizing the effect of their own childhood experiences on their parenting behavior, and learning the importance of touch and children’s emotions. Across all sessions, parent trainers engaged parents in structured activities with their children and then provided feedback on observations of participants’ parenting behavior, both in real-time and by playing back video recordings from the sessions. 

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 parental sensitivity were removed to distinguish it from ABC-Infant.
