ABSTRACT

This exploratory study examines how three types of fit (technical, cultural, and political) between an evidence-based practice and adopting organization explain fidelity in terms of quantity and quality of core components implemented. Using data from 20 supportive housing programs, fidelity was calculated using a quantitative scale and fit was coded using qualitative program director interviews. Relationships between fidelity and fit were tested with Fisher’s exact tests. Cultural fit predicted both high quality and quantity fidelity, and technical fit predicted high-quality fidelity. Interviews provided qualitative examples of how fit influenced implementation. Study results provide preliminary support for the relationship between practice-organization fit and fidelity.

摘要

这项探索性研究考察了基于证据的实践与采用组织之间的三种类型的契合度（技术，文化和政治上）如何根据所实施的核心组件的数量和质量来说明保真度。使用来自20个支持性住房计划的数据，使用定量表计算保真度，并使用定性计划主任访谈对拟合度进行编码。保真度与适合度之间的关系用Fisher的精确检验进行了检验。文化适应性预测高质量和数量保真度，而技术适应性预测高质量保真度。访谈提供了适合度如何影响实施的定性示例。研究结果为实践组织适应度与忠诚度之间的关系提供了初步支持。
