Perinatal nursing research: a 25-year review--1976-2000.

Parent-infant nursing research from 1976-2000 is reviewed through four groups of studies: development of research instruments, studies of mothers and fathers through the childbearing years, studies of newborns (both healthy and at risk), and studies of special populations. Potential directions for maternal/parent/newborn nursing research in the 21st century are suggested.
