The efforts expended by pediatricians in a variety of private practice settings to educate mothers of first-born children about child behavior and development were examined in relation to various outcome measures of mother and child functioning over a time period of one-and-a-half years.Mothers learned more about child development in group settings than in solo practice settings, but differences between medical groups with and without nurse practitioners were not significant. Mothers receiving care from pediatricians who made at least a moderate effort to teach, learned more about child development, described more use of positive contact with their children, and felt they were helped more in their childrearing efforts than did mothers receivingThe value of well-child visits as they are currently conducted is being questioned.
