This prospective, longitudinal investigation examined factors that influenced the use of well-baby services among a low-income, minority, high-risk group. The health belief model was used as the theoretical framework. Data were collected from 44 primiparous, black mothers attending an urban maternal child health care clinic by interviews at the first and sixth months after the birth of their infants. Analysis focused on the cues component of the model and explored the kinds of cues that influenced the mothers to bring their babies to the well-baby clinic. One important finding was that for mothers influenced by health information from radio or television, FYI commercials on television were most often reported.
