This paper is a discussion of the use of the Levine Conservation Model to guide the investigation of an exercise intervention to mitigate cancer-related fatigue.
Researchers use conceptual models or theoretical frameworks to provide an organizing structure for their studies, to guide the development and testing of hypotheses, and to place research finding within the context of science. Selection of an appropriate and useful framework is an essential step in the development of a research project.
A descriptive approach is used to present the components of the conceptual model and details of the articulation of the study intervention and outcomes with the model.
The Levine Conservation Model provided a useful framework for this investigation, conducted in 2002-2006, of the effects of exercise on fatigue and physical functioning in cancer patients. The four conservation principles of the model guided the development of the exercise intervention, the identification of salient outcomes for patients, and the selection of appropriate instruments to measure study variables. The model is also proving useful in the analysis and interpretation of data in relation to the conservation principles.
Use of an appropriate conceptual model facilitates the design and testing of theory-based interventions and the development of science to support nursing practice.
本文探讨使用莱文守恒模型来指导一项减轻癌症相关疲劳的运动干预研究。
研究人员使用概念模型或理论框架为其研究提供组织结构，指导假设的形成与检验，并将研究结果置于科学背景中。选择合适且有用的框架是开展研究项目的关键步骤。
采用描述性方法呈现概念模型的组成部分以及该研究干预措施与模型的衔接细节和结果。
莱文守恒模型为2002年至2006年开展的这项关于运动对癌症患者疲劳及身体功能影响的研究提供了有用的框架。该模型的四个守恒原则指导了运动干预措施的制定、确定患者的显著结果以及选择测量研究变量的合适工具。该模型在与守恒原则相关的数据的分析和解释中也证明是有用的。
使用合适的概念模型有助于基于理论的干预措施的设计与检验以及支持护理实践的科学发展。
