Study Participants

The study is a randomized controlled trial. The Division of Family Services in Delaware referred mothers who had an unsubstantiated allegation of child neglect to participate in the study. After eligible mothers consented to participate, researchers randomly assigned 13 mothers to the Attachment and Biobehavioral Catch-Up (ABC) condition and 11 to the Developmental Education for Families (DEF) (control) condition.Based on the screening criteria, all mothers had children ages 6 to 20 months old and a household income less than $35,000. Most mothers identified as African American or European American.



Home Visiting Services

ABC is an intervention designed to teach parents nurturing, sensitive, and nonfrightening ways of interacting with their children. The intervention was implemented across 10 weekly sessions in parents' homes with a parent coach interacting each week with the parent and child. Parents are also assigned homework each week to reinforce the skills taught during the session.

Comparison Conditions

DEF is another home-based intervention. Like ABC, it is also a manualized treatment conducted over 10 sessions with a parent coach. However, its focus is on improving children's gross and fine motor, cognitive, and language skills.

Staff Characteristics and Training

The characteristics and training of the parent coaches are not described.
