The authority decision occurs by adoption among very few individuals with high positions of power within an organization. They will use an innovation if they perceive it will give them a social edge. Early adopters have a higher social status, financial liquidity, advanced education and are more socially forward than late adopters.
Indirect costs may also be social, such as social conflict caused by innovation. These people are very willing to take risks, and are often the first to develop new ideas.
This process works well within an organization or in society at large. Katz is also credited for first introducing the notion of opinion leaders, opinion followers and how the media interacts to influence these two groups.
These models are particularly good at showing the impact of opinion leaders relative to others. It does not foster a participatory approach to adoption of a public health program.
Limitations of Diffusion of Innovation Theory There are several limitations of Diffusion of Innovation Theory, which include the following: In the dynamics of such models, each node is assigned a current state, indicating whether or not the individual has adopted the innovation, and model equations describe the evolution of these states over time.
Authority Innovation-Decision made for the entire social system by individuals in positions of influence or power. The second speediest are the early adopters, who like to be the trendsetters.
The last adopters are called the laggards, who are the most fearful of change. Homophilous individuals engage in more effective communication because their similarities lead to greater knowledge gain as well as attitude or behavior change. Innovation Adopter Categories — time is also critical within the five adopter categories and how they influence one another to support full saturation of the innovation.
Mathematical programming models such as the S-D model apply the diffusion of innovations theory to real data problems. Once one previously homophilous tie adopts the behavior or innovation, the other members of that group are more likely to adopt it, too.
Adopter categories[ edit ] Rogers defines an adopter category as a classification of individuals within a social system on the basis of innovativeness. Theory in Nursing Informatics Column.
Laggards - These people are bound by tradition and very conservative. Strategies to appeal to this population include information on how many other people have tried the innovation and have adopted it successfully.
Adoption strategies[ edit ] Rogers outlines several strategies in order to help an innovation reach this stage, including when an innovation adopted by a highly respected individual within a social network and creating an instinctive desire for a specific innovation.
Indirect costs may also be social, such as social conflict caused by innovation. One network carries information and the other carries influence. It is extremely difficult, if not impossible, to measure what exactly causes adoption of an innovation.
These opinion leaders serve as valuable integral change agents who influence their peers through peer to peer communication, role modeling, and networking. This process works well within an organization or in society at large.
Re-invention Re-invention is another important consideration. Communication Channels Communication Channels refers to the rate and degree that people talk about and spread the news about the innovations. It does not foster a participatory approach to adoption of a public health program.
Rogers mapped out this process, stressing that in most cases, an initial few are open to the new idea and adopt its use. Rate is usually measured by the length of time required for a certain percentage of the members of a social system to adopt an innovation. The champion plays a very similar role as the champion used within the efficiency business model Six Sigma.
Peer subjective evaluations of an innovation are very influential. The original five categories are illustrated in the bell-shaped curve image below.
These individuals typically have an aversion to change-agents. Borrowing from social network analysis, each node is an innovator, an adopter, or a potential adopter. This rate of adoption is influenced by the innovation characteristics introduced above.
Adopter category Definition Innovators Innovators are willing to take risks, have the highest social status, have financial liquidity, are social and have closest contact to scientific sources and interaction with other innovators.
The results are usually concerned with issues of societal well-being. Once one previously homophilous tie adopts the behavior or innovation, the other members of that group are more likely to adopt it, too.
There are a number of behavioral change theories that guide work in health and human services, but I particularly like Diffusion of Innovations because it emphasizes how social networks and interpersonal relationships may impact your success in getting people to try something new.

Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. Everett Rogers, Opinion leaders have the most influence during the evaluation stage of the innovation-decision process and on late adopters.
Diffusion of Innovation Framework for Evaluation The diffusion of innovations approach to program evaluation recognizes that a variety of factors influence the adoption of a practice.
This approach provides insight into why educational program participants adopt or reject a practice on which they have received information or training.
Diffusion of Innovations Theory Diffusion of innovations is a theory profound by Everett Rogers that seeks to explain how, why, and at what rate new ideas and technology spread. Rogers argues that diffusion is the process by which an innovation is communicated over time among the.
The diffusion of innovation theory does not quite give a clear prediction of how the innovation will be successful after going through the S curve.
An innovation may mutate in the process of diffusion thereby affecting the diffusion process. Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread.
Everett Rogers, a professor of communication studies, popularized the theory in his book Diffusion of Innovations; the book was first published inand is now in its fifth edition (). Rogers argues that diffusion is the process .Evaluation of the diffusion of innovation theory
