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.
The study was conducted in a large mid-Atlantic city.
ABC-Infant, a brief parenting intervention consisting of 10 sessions each an hour long, occurred weekly in participants’ homes. Parent coaches conducted the sessions and provided parents with real-time feedback using videos of the sessions to highlight parenting strengths and weaknesses. The coaches also engaged parents in structured activities with their children and incorporated research findings in the information provided to the parents. The sessions focused on five topic areas: providing nurturance and interpreting child signals, responding in sensitive ways and delighting in the child, refraining from frightening behavior, identifying the parent’s personal challenges that may hinder nurturing parenting behavior, and consolidating the information and skills that parents learned.
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.
The staff in both groups were selected based on their experience in working with children and their interpersonal skills. Parent coaches received training and supervision as appropriate to their roles.
