The designs and methods of published nursing research: 1956-1983.

This study describes the relative frequencies over time of designs and methods used in nursing research articles published in three refereed journals. All articles published in 1956, 1961, 1966, 1971, 1976, 1981, and 1983 were reviewed (N = 434); 83% were research articles. Methodological research comprised 11% and historical research 1% of the 362 research articles. The designs of the remaining 317 research reports were classified as experimental (27%) or observational (73%). Use of experimental designs peaked in the mid-1960s (41%) and appears to be on the decline (20% in 1983). Cross-sectional studies predominated throughout the period (49%). Methods, including types of subjects, sample selection, and data collection instruments, are described and analyzed for time trends. The findings are discussed in light of the designs and methods advocated in nursing texts and literature.
