ESSAY: COLLAPSE Theory, Research, and Evidence-Based Practice

As they explore the world around them, young children often want to know the “why” and “how” of the things they observe. This is similar to what researchers do when they approach a new problem. Researchers develop new theories or build on old ones to explain the “why” of the world around them. They use models and conceptual frameworks to help explain “how” the processes and events they observe occur. Together, theories and models provide an understanding of the world and allow researchers to explore it in meaningful ways.

Virtually all research questions can benefit from the use of an existing theory or model. Researchers should consider their research questions and select the most suitable theory or model, which then serves as a foundation for the research design. The selection of a theory or model is an important part of the research process.

In this Discussion, you focus on the role of theory and models in research and evidence-based practice.

In the last decade, there has been a significant progress towards adopting the use of theoretical approaches in not only providing better understanding but also in explaining how and why some scientific implementations fail while others succeed (Polit & Beck, 2017).  Theories or models are crucial in facilitating appropriate application and selection of relevant and most suitable approaches in implementing research and practices.
