This analysis describes the characteristics of nursing research today, and identifies trends and changes in research over the past three decades. A sample was drawn from four nursing research journals of 137 substantive studies, 14 published in 1952–53, 20 in 1960, 40 in 1970, and 63 in 1980. The analysis revealed that over this period nursing research (1) increased substantially in amount; (2) became more clinically focused; (3) demonstrated a greater theoretical orientation; and (4) became more sophisticated and sound in methods employed. Among the limitations noted were insufficient conceptualization and the failure to build a cumulative science. Suggestions are offered for future research.
