Advances in Nursing Science: July/September 2017 - Volume 40 - Issue 3 - p E1-E19 doi: 10.1097/ANS.0000000000000152 Buy Metrics Abstract Transitions Theory (TT) states that change and transition are phenomena that make humans more vulnerable to health risks. Transitions Theory was evaluated through a text analysis of 4 publications, 3 nursing expert focus group interviews in Switzerland, and a mapping review of the transition literature of the last 5 years. Although the implementation of TT into Swiss nursing practice seems problematic due to conceptual deficiencies, transition is a meaningful nursing topic. The connection between TT, research, and practice is weak. Yet guidelines for theory description, theory analysis, and theory actualization could enhance and strengthen the body of knowledge in nursing. © 2017 Wolters Kluwer Health, Inc. All rights reserved.
