CORE--EVALUATION CORE

评估干预措施可能带来的益处的能力对于发展科学知识以指导护理实践至关重要。然而，干预研究的复杂性，即人类健康行为的复杂性，沿着生物，行为和环境因素之间的相互作用，对寻求描述干预影响的研究人员提出了重大的方法学挑战。此外，在医疗保健的问责制和护理研究的方法严谨性的需要，提高了相关的，可靠的，有效的方法来衡量和评估干预措施的结果的需要。这包括收集和分析成本数据，以满足对新的和现有的卫生保健干预措施的健康效益和经济影响的信息需求。评价核心将提供重要咨询， 技术支持和指导，以加强约翰霍普金斯大学护理学院干预研究的评价方面。 评估核心将为中心的试点项目以及教师当前和未来的研究提供必要的专业知识和服务。评价核心的具体目标是： 1.协助教师选择，分析和解释健康，生活质量和成本结果。 2.提供统计咨询。 3.为数据管理和数据完整性维护提供技术支持。 4.协助教师分析仪器的心理测量特性。 5.就过程评价的设计提供咨询。

The ability to evaluate possible benefits of an intervention is essential to the development of scientific knowledge to guide nursing practice. However, the complicated nature of intervention research, namely the complexities of human health behaviors along with the interplay between biological, behavioral and contextual factors present significant methodological challenges to researchers seeking to delineate the impact of an intervention. In addition, the demand for accountability in health care and the need for methodological rigor in nursing research have heightened the need for relevant, reliable, and valid methods for measuring and evaluating the outcomes of interventions. This includes the collection and analysis of cost data addressing the need for information about both the health benefits and the economic implications of new and existing health care interventions. The Evaluation Core will provide the critical consultation, technological support, and mentorship to strengthen the evaluative aspects of intervention research in the Johns Hopkins University School of Nursing. The Evaluation Core will provide essential expertise and service to the pilot projects of the Center as well as to the current and future research of faculty. The specific aims of the Evaluation Core are to: 1. Assist faculty in selecting, analyzing and interpreting health, quality of life, and cost outcomes. 2. Provide statistical consultation. 3. Provide technological support for data management and maintenance of data integrity. 4. Assist faculty in the analysis of the psychometric properties of instruments. 5. Provide consultation on the design of process evaluations.
