The present study is an attempt to present a process of relationship among theory, research, and practice in nursing. First, the term theory is defined as well as each of the theory's basic elements. Secondly, the concepts of research and practice are discussed in terms of their potential for stemming, testing, and redefining the theory. Thirdly, the concepts of theory, research and practice are presented as a triple spiral which works as a dinamic process. Within this process the theory, research, and practice interact to improve each other.
