Intervention studies that address the goals of the Healthy People initiative are increasing, and many focus on health concerns of children and adolescents. The purpose of this paper is to present strategies and discuss the rationale for including intervention fidelity in study design.
Researchers need to verify that their interventions were delivered as designed (intervention fidelity), and that variations from the design can be assessed. Infidelity can result in non-significant findings that are not due to the study design but rather to elements that affected the intervention delivery.
Addressing intervention fidelity in study design supports the researcher's conclusion about associations between intervention and outcomes and helps reduce premature abandonment of potentially useful interventions.
针对“健康人民”倡议目标的干预研究日益增多,许多研究聚焦于儿童和青少年的健康问题。本文旨在介绍策略并讨论在研究设计中纳入干预保真度的基本原理。
研究人员需要验证其干预措施是否按设计实施(干预保真度),以及是否可以评估与设计的差异。干预不保真可能导致无显著结果,这并非由于研究设计,而是由于影响干预实施的因素。
在研究设计中考虑干预保真度有助于研究人员得出关于干预与结果之间关联的结论,并有助于减少过早放弃可能有用的干预措施。
