Davis Company PP New York, NY SN 9780803661134 LK fadavispt.mhmedical.com/content.aspx?aid=1187146121 RD 2024/03/28 AB In the development of questions for research or the use of published studies for evidence-based practice (EBP), we must be able to establish logical foundations for questions so that we can interpret findings. This is the essential interplay between theory and research, each integral to the other for advancing knowledge. Theories are created out of a need to organize and give meaning to a complex collection of individual facts and observations. The purpose of this chapter is to discuss components of theories, mechanisms for developing and testing clinical theories, and how we apply theory to research and the application of evidence.
