Content: Afterwards, for almost century reports of nursing  research were rare. Research and theory developed separately in nursing. Between 1928 and 1959 only 2 out of 152 studies  reported a theoretical basis for the research design. In 1970’s growing number of nurse theorists were  seeking researchers to test their models in research and  clinical application
Grand nursing theories are still not widely used. In  1990’s borrowed theories were used more. Now the focus of research and theory have moved more  towards middle range theories
Purpose  of Theory in Research
To identify meaningful and relevant areas for study. To propose plausible approaches to health problems. To develop or refine theories
Define the concepts and proposed relationships between  concepts. To interpret research findings
To develop clinical practice protocols. To generate nursing diagnosis.
