Study Characteristics

Study Participants The sample included 1,308 mothers with children about 5.5 years old at assessment. All women enrolled in Healthy Steps within four weeks of the child’s birth. Study enrollment occurred between September 1996 and November 1998. Just over one in three parents had a college degree, and 40% had incomes above $50,000 at baseline. Most study participants were white (65%) or African American (21%). The most common maternal age groups were 20-29 (48%) and over 30 (42%).
Setting The six sites—Allentown, PA, Amarillo, TX, Florence, SC, Iowa City, IA, Pittsburgh, PA, and San Diego, CA—were randomly assigned as part of the national evaluation. (There were nine other sites that used quasi-experimental comparisons. These comparisons received a low rating, however. See Study Ratings for details.) Sites were group practices, hospital-based clinics, or pediatric practices in health maintenance organizations.
Home Visiting Services Healthy Steps Specialists provided well-child care, up to six home visits in the first three years, a child development telephone information line, child development and family health checkups, written materials for parents that emphasize prevention, parent group meetings, and links to community resources. Families actually received fewer than two visits, on average, during the child’s first 2.5 years.
Comparison Condition Children in the control group received routine pediatric care but had no exposure to the Healthy Steps Specialist or to Healthy Steps materials.
Staff Characteristics and Training Specialists were early childhood educators, nurses, nurse practitioners, social workers, or professionals with other relevant expertise. Each attended annual trainings conducted by the Boston University Healthy Steps team and administered services in cooperation with pediatricians and pediatric nurse practitioners. Sites also received program and training manuals and technical assistance through biweekly teleconferences. Implementation of written protocols was monitored by the Healthy Steps national program office. See Guyer et al. (2003) for more details.
