本文对创新扩散研究范式的变迁进行了回顾和思考，并对这一社会变迁理论的进一步发展提出了建议。随着时间的推移，传播研究的主要重点进行了比较，特别注意应用的传播理论为基础的概念，传播科学的类型。观察到相当程度的范式演变。经典的扩散模型侧重于采用者的创新性，个人作为决策的中心，沟通渠道，并采用作为事后观察性研究设计的主要结局指标。所讨论的传播系统是集中式的，通常假设实现的保真度。目前的传播研究和实践的特点是更好地测试的干预措施，操作一个或多个扩散理论为基础的概念和概念从其他变化的方法，涉及复杂的组织作为单位的采用，并侧重于实施问题。Foment的特点传播和实施研究，反映了其跨学科的根源和传播的必要性，以证据为基础的创新作为传播科学的翻译研究的新范式的基础。
The article provides a review and considers how the diffusion of innovations research paradigm has changed, and offers suggestions for the further development of this theory of social change. Main emphases of diffusion research studies are compared over time, with special attention to applications of diffusion theory-based concepts as types of dissemination science. A considerable degree of paradigmatic evolution is observed. The classical diffusion model focused on adopter innovativeness, individuals as the locus of decision, communication channels, and adoption as the primary outcome measures in post hoc observational study designs. The diffusion systems in question were centralized, with fidelity of implementation often assumed. Current dissemination research and practice is better characterized by tests of interventions that operationalize one or more diffusion theory-based concepts and concepts from other change approaches, involve complex organizations as the units of adoption, and focus on implementation issues. Foment characterizes dissemination and implementation research, reflecting both its interdisciplinary roots and the imperative of spreading evidence-based innovations as a basis for a new paradigm of translational studies of dissemination science.
