A study gauged the effectiveness of prenatal intervention with low socioeconomic, first-time fathers whose partners were experiencing a high- or low-risk pregnancy. Of the 67 men, who were recruited by their partners, half were randomly assigned to participate in an intervention program designed to acquaint fathers-to-be with information, insights, and clinically appropriate techniques in responsive care for infants. Intervention group fathers received two intensive sessions on the nature and capabilities of the preborn and newborn, sensitive responsiveness to preborn and newborn cues and partner cues. After infants' births, fathers were videotaped with infants during two feeding interactions. At time one, intervention fathers were rated from videotapes as significantly more sensitive during feeding interactions. At time two, 1 month later, differences between father groups approached significance. It is concluded that findings demonstrate that an information support program for first-time, low socioeconomic class fathers is feasible, particularly when women in high- or low-risk pregnancies enlist their partners' participation.
