One method of research for evidence-based practice in nursing is 'qualitative research': The word implies an entity and meanings that are not experimentally examined or measured in terms of quantity, amount, frequency, or intensity. With qualitative research, researchers learn about patient experiences through discussions and interviews.
Repeated measures design is a research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods. [1] For instance, repeated measurements are collected in a longitudinal study in which change over time is assessed.
The National Institute of Nursing Research (NINR), as part of the U.S. National Institutes of Health, supports clinical and basic research to establish a scientific basis for the nursing care of individuals across the life span—from management of patients during illness and recovery, to the reduction of risks for disease and disability, and the promotion of healthy lifestyles.
Practitioner research refers to research and/or workplace research such as evaluation performed by individuals who also work in a professional field as opposed to being full-time academic researchers.
