The Better Babies Project is attempting to intervene with inner city pregnant women, many of whom are poor, to change their behavior in order to reduce the many behavioral risks associated with delivering a low birthweight infant. The research objective of this intervention is to offer and document the provision of consistent and comprehensive services to pregnant women with differing risk factors and differing needs. Several concepts underlie this intervention approach. They include: (1) one-on-one delivery by paraprofessionals to participants; (2) the provision of a comprehensive set of services; and (3) monthly development and reassessment of needs-based intervention plans. Some of the tools which were developed to manage a pregnancy intervention fall into three categories: (1) standardized assessment inventories and records of needs and services; (2) an administrative data base that records needs and services; and (3) interim measures of success in applying the intervention. Included are sample handouts and forms used in the intervention and preliminary data tables. (RJC)
