Collective Innovation-Decision made collectively by all participants. Authority Innovation-Decision made for the entire social system by individuals in positions of influence or power. Rate of adoption[ edit ] The rate of adoption is defined as the relative speed at which participants adopt an innovation. 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.
Rogers inis one of the oldest social science theories. It originated in communication to explain how, over time, an idea or product gains momentum and diffuses or spreads through a specific population or social system. The end result of this diffusion is that people, as part of a social system, adopt a new idea, behavior, or product.
Adoption means that a person does something differently than what they had previously i. The key to adoption is that the person must perceive the idea, behavior, or product as new or innovative.
It is through this that diffusion is possible. Adoption of a new idea, behavior, or product i. Researchers have found that people who adopt an innovation early have different characteristics than people who adopt an innovation later.
When promoting an innovation to a target population, it is important to understand the Diffusion of innovations and compatibility of the target population that will help or hinder adoption of the innovation.
There are five established adopter categories, and while the majority of the general population tends to fall in the middle categories, it is still necessary to understand the characteristics of the target population.
When promoting an innovation, there are different strategies used to appeal to the different adopter categories. Innovators - These are people who want to be the first to try the innovation. They are venturesome and interested in new ideas. These people are very willing to take risks, and are often the first to develop new ideas.
Very little, if anything, needs to be done to appeal to this population. Early Adopters - These are people who represent opinion leaders. They enjoy leadership roles, and embrace change opportunities.
They are already aware of the need to change and so are very comfortable adopting new ideas. Strategies to appeal to this population include how-to manuals and information sheets on implementation. They do not need information to convince them to change. Early Majority - These people are rarely leaders, but they do adopt new ideas before the average person.
That said, they typically need to see evidence that the innovation works before they are willing to adopt it.
Late Majority - These people are skeptical of change, and will only adopt an innovation after it has been tried by the majority. Strategies to appeal to this population include information on how many other people have tried the innovation and have adopted it successfully.
Laggards - These people are bound by tradition and very conservative. They are very skeptical of change and are the hardest group to bring on board. Strategies to appeal to this population include statistics, fear appeals, and pressure from people in the other adopter groups. There are five main factors that influence adoption of an innovation, and each of these factors is at play to a different extent in the five adopter categories.
Relative Advantage - The degree to which an innovation is seen as better than the idea, program, or product it replaces.
Compatibility - How consistent the innovation is with the values, experiences, and needs of the potential adopters. Triability - The extent to which the innovation can be tested or experimented with before a commitment to adopt is made.
Observability - The extent to which the innovation provides tangible results. Limitations of Diffusion of Innovation Theory There are several limitations of Diffusion of Innovation Theory, which include the following: Much of the evidence for this theory, including the adopter categories, did not originate in public health and it was not developed to explicitly apply to adoption of new behaviors or health innovations.
It does not foster a participatory approach to adoption of a public health program. It works better with adoption of behaviors rather than cessation or prevention of behaviors. This theory has been used successfully in many fields including communication, agriculture, public health, criminal justice, social work, and marketing.
In public health, Diffusion of Innovation Theory is used to accelerate the adoption of important public health programs that typically aim to change the behavior of a social system. For example, an intervention to address a public health problem is developed, and the intervention is promoted to people in a social system with the goal of adoption based on Diffusion of Innovation Theory.
The most successful adoption of a public health program results from understanding the target population and the factors influencing their rate of adoption.Rogers () was the first one to introduce and define the term compatibility in his Innovation Diffusion Theory.
“Compatibility assesses the extent of congruence between a new technology and various aspects of the individual and the situation in which the technology will be utilized” (Karahanna et al., , p. ). Rogers () was the first one to introduce and define the term compatibility in his Innovation Diffusion Theory.
“Compatibility assesses the extent of congruence between a new technology and various aspects of the individual and the situation in which the technology will be utilized” (Karahanna et al., , p.
). In a series of diffusion studies across multiple areas, Rogers found that innovations that have these 5 characteristics -high relative advantage, trialability, observability, and compatibility, and low complexity- are likely to succeed over innovations that do not.
The Diffusion of Innovation Theory was first discussed historically in by the French sociologist Gabriel Tarde (Toews, ) who plotted the original S-shaped diffusion curve, followed by Ryan and Gross () who introduced the adopter categories that were later used in the current theory popularized by Everett Rogers.
