Although retrospective descriptive studies still predominate, more prospective studies, randomized controlled trials, multi-site studies, and quasi-experimental designs are being conducted. Qualitative methods are helping to measure nontraditional outcomes. A research agenda should be established based on discussion and debate within the profession. Midwife investigators need to build research teams and collaborate with other disciplines. Key areas for future research include alternative therapies, breastfeeding, cost-effectiveness, cultural studies, gynecology, health policy, menopause, postpartum care, substance abuse interventions, and the woman's experience of birth and midwifery care.
