B.5 Implementation, adoption, and evaluation Flashcards
Apply information science theories in the implementation, adoption and evaluation of information systems.
What are examples of theories relevant to implementing information systems in healthcare?
Technology acceptance model, theory of reasoned action, diffusion of innovation, social cognitive theory.
Who developed the technology acceptance model (TAM) and in what year?
Davis in 1986.
What does the theory of reasoned action suggest about behavioral intentions?
They depend on the interplay between attitudes and subjective norms.
What are attitudes in the context of the theory of reasoned action?
The totality of the subject’s beliefs concerning the behavior at hand.
What influences attitudes according to the theory of reasoned action?
- Strength of relevant behavioral beliefs
- Evaluation of potential outcomes.
What are subjective norms in the theory of reasoned action?
Perceptions of relevant groups or individuals that may affect the subject’s behavior.
What is the main predictor of behavior according to the theory of reasoned action?
Behavioral intention.
What predicts an individual’s actual use of an information system in the technology acceptance model?
Their intention to use it.
What determines the intention to use an information system in the technology acceptance model?
- Usefulness
- Ease of use.
What are the five categories of adopters in the diffusion of innovation theory?
- Innovators
- Early Adopters
- Early Majority
- Late Majority
- Laggards.
What characteristics define Innovators in the diffusion of innovation theory?
Risk-takers who want to be the first to try the innovation.
What defines Early Adopters in the diffusion of innovation theory?
Opinion leaders and change agents who understand the need to change.
What is a key trait of the Early Majority in the diffusion of innovation theory?
They typically need evidence that the innovation works before adopting it.
What strategies are effective for the Late Majority in the diffusion of innovation theory?
Describing how many people have adopted the innovation successfully.
What is the main challenge evaluators face according to the evaluation theories discussed?
Measuring expected results from an intervention and attributing those results to the activities of the intervention.
What is evaluation defined as in the context of health informatics?
A rigorous, systematic and objective process to assess a program’s effectiveness, efficiency, appropriateness and sustainability.
What does a theory of change explain?
How an intervention is expected to produce its results and outlines the mechanisms of change.
What are the steps involved in developing a theory of change?
- Defining a logic model with clear results chains
- Identifying relevant assumptions and risks
- Identifying other contextual factors.
True or False: The technology acceptance model is primarily applied in consumer contexts.
False.
Fill in the blank: The diffusion of innovation theory was developed by _______ in 1962.
Rogers.
What is self-efficacy in the context of social cognitive theory?
A person’s confidence level in their ability to perform a behavior.
What is one perceived limitation of the theory of reasoned action?
Some individuals’ inability to translate intentions into actions due to skill or resource deficits.
