Amplifying your impact by bringing social innovations to scale.

Diffusion Associates

Innovative ideas often fail to produce effective interventions that then spread to those in need. When spread does occur, implementation may not be sustained or local adaptation renders the innovation ineffective.

We can change that. Diffusion Associates works with social innovators and sponsors committed to designing and scaling out effective interventions.

Together, we can improve the lives of more individuals and the well-being of more communities.


Scaling Social Innovations

Drawing from expertise in developmental evaluation, implementation science, and diffusion of innovations, we work with you to develop, implement, and scale out social innovations.


Innovation characteristics describe how we think about new practices and programs. How do potential adopters perceive the innovation? Is it too costly or complex? Are the innovation’s components well defined and tied to a theory of change? Which components can be adapted to a local context and which should not? We (re)design innovations to increase the likelihood of adoption and accelerate scaling out. 


Scaling out requires planning. Should an organization expand its capacity, use a franchise model, or partner with larger networks? Does the innovation require strict fidelity or can the innovation be adapted by implementers? Is the organization ready to scale out the innovation? Are adopters ready to implement it? We develop scaling strategies that fit the values and resources of innovators and implementers. 

implementation analysis

Adapting innovations during implementation can lead to sustained implementation, but it can also change the impact of a program. What adaptations are taking place? What factors influence adaptation? Do adaptations change the impact of the program? Why do adopters discontinue implementation? We assist innovators in developing implementation guidance so more people are served with comparable benefits.

Evaluation Planning

Effectiveness or impact may change as an innovation is adapted and as populations change. Does the innovation show the same or similar effects as it did prior to scaling? Does it work differently for different populations? If so, how? And how can innovators and implementers share evaluation responsibilities? We design collaborative evaluations to monitor fidelity and adaption, and to assess effectiveness.

We conclude with suggestions for future evaluation and research to improve its performance in the field as it scales out.

Wallace Foundation

Strategies to Scale Up Social Programs

Scaling what works is a crucial component of systems change. How to scale (“pathways”), whom to involve (“partnerships’), and retention of program quality (“fidelity”) are three strategic decisions that are critical to the scaling out of effective social programs. This study explores these strategic decisions, how they are related, and how they can work in concert.

Teachers Development Group

Rehumanizing Math Early On

Supporting PK-Grade 2 teachers in creating and implementing math learning opportunities authentic to the lived experiences of young learners is the goal of a Teachers Development Group (TDG) grant funded by the Heising-Simons Foundation.

We conclude with suggestions for future evaluation and research to improve its performance in the field as it scales out. 

Strategies to Scale Up Social Programs: Pathways, Partnerships and Fidelity
This study funded by the Wallace Foundation and conducted by Larson, Dearing and Baker, assesses the conditions and circumstances that favor one scaling-up strategy over others. The primary focus is on collaboration and partnerships found in 45 social innovations that scaled up using different strategies.

An Agenda for Research on the Sustainability of Public Health Programs
In this American Journal of Public Health publication, Scheirer and Dearing provide guidance for research and evaluation of health program sustainability, including definitions and types of sustainability, specifications and measurements of dependent variables, definitions of independent variables or factors that influence sustainability, and suggestions for designs for research and data collection.

Design Research and the Diffusion of Innovations
This chapter in The Handbook of Design Research Methods in Education: Innovations in Science, Technology, Engineering and Mathematics Learning and Teaching by Larson and Dearing introduces the diffusion of innovation paradigm and explicates how, in the case of consequential innovations such as design research, diffusion operates. It poses questions that can facilitate a purposive diffusion strategy for accelerating the spread of design research as a new and effective methodology for use by educational researchers.

Designing for Diffusion of a Biomedical Intervention
In this American Journal of Preventive Medicine publication, Dearing, Larson and others apply what is known about diffusion to the general case of biomedical interventions and specifically pre-exposure prophylaxis (PrEP). It defines designing for diffusion as the taking of strategic steps early in the process of creating and refining an evidence-based intervention to increase its chances of being noticed, positively perceived, accessed, and tried and then adopted, implemented, and sustained in practice.

Diffusing STEM Pedagogies: The Role of Opinion Leaders
Larson and Meyer use literature and exploratory data to contrast awareness and persuasion and suggest that opinion leaders in academic departments can play a critical role in the diffusion of STEM pedagogies in this article from Metropolitan Universities.

Disseminating Proven Approaches to Physical Activity Promotion
Approaches from diffusion of innovations and social marketing are used to propose efficient means to promote and enhance the dissemination of evidence-based physical activity programs in this article by Dearing, Maibach and Buller published in the American Journal of Preventive Medicine .

How Centers Work: Building and Sustaining Academic Nonprofit Centers
In this publication from the W. K. Kellogg Foundation, Larson and Barnes share findings about the development and sustainability of academic nonprofit centers. They describe how these centers work – how they were created, who leads them, how they are lead, and how they gain academic credibility and institutional stability.

Local Reinvention of the CDC HIV Prevention Community Planning Initiative
In the Journal of Community Health, Larson, Dearing and others conclude that to fully achieve the potential of HIV prevention community planning a distinction should be drawn so that information-seeking tasks are centrally coordinated and decision-making tasks are decentralized.

Next Steps in Designing for Diffusion of Pre-Exposure Prophylaxis
Dearing, Norton and Larson suggest that pre-exposure prophylaxis, a biomedical intervention with potential to be highly effective if well implemented and used, appears well suited to sequential demonstration, first for experimental purposes with the objective of assessment of feasible delivery methods, and second for exemplary purposes with the objective of promoting its effective implementation in this article in the American Journal of Preventive Medicine.
