Informatics Final- Week 11 Flashcards
Why use theory?
Theory based interventions have greater effects on behavior change (still need to know more about how to apply theory though)
What four theories are most commonly used online?
- Transtheoretical model
- Social-cognitive theory
- Theory of reasoned action/planned behavior
- Elaboration of likelihood model
What is the transtheoretical model?
Stages of change, decisional balance (pro/con), self-efficacy (confidence & temptation)
What are the stages of change?
Pre-contemplation, contemplation, preparation, action, maintenance, termination
What are the early stages of processes of change?
Consciousness raising, dramatic relief, environmental reevaluation, self-reevaultion, self-liberation
What are the later stage processes of change?
Helping relationships, counterconditioning, contingency management, stimulus control, social liberation
What is the social-cognitive theory?
Reciprocal determinism (environment, behavior, individual factors intact; multiple avenues to influence behavior)
What are individual factors in reciprocal determinism?
Knowledge, skills, self-efficacy, outcome expectations, goals
What skills are part of SCT intervention strategies at the individual level?
Self-regulation, stress management, monitoring heart rate, counting calories
What are outcome expectations of SCT intervention strategies are the individual level?
persuasive communication: risks and benefits
What is meant by goals in relation to SCT interventions at the individual level?
Setting goals and monitoring progess
What are SCT intervention strategies for environmental factors?
Social environnement (behavior change w/ buddy, support on message boards); Physical environment (↑ availability of healthy snacks, avoid places where you smoked)
How is SCT applied to increase self-efficacy?
Practice the task
Observe a model
Get feedback
Reduce anxiety
What aspects are parts of the Theory of Planned Behavior (TPP)?
Behavioral beliefs (attitude toward behavior), normative beliefs (subjective norm), control beliefs (perceived behavioral control); all lead to behavioral intention which leads to behavior (** see slide 21 of week 11 is this is confusing)
What is the Elaboration Likelihood Model (ELM)?
Explains how people process information and forms the basis for message tailoring
What are the two processing routes? (ELM)
- central: personally relevant information is more deeply process, retained longer, linked to enduring attitude and behavior change
- peripheral: more superficial processing, attractive of message source (?)
What is meant by tailoring? (ELM)
- combination of information or change strategies intended to reach one specific person
- based on unique characteristics of that person and related to outcome of interest; derived from individual assessment
What is the rationale for tailoring? (ELM)
personalized, relevant information -> deeper processing -> attitude and behavior change
What are the steps in the tailoring process? (ELM)
- Determine tailoring variables
- Create a message library
- Determine algorithm
- Administer individual assessment
- Create tailored message
“Summary: For a person to change:” (main points from this lecture)
- Strong positive intention
- No environmental constraints
- Must have the necessary skills
- Believe the advantages outweigh the disadvantages
- Perceive social pressure to perform the behavior than to not perform it
- Believe the behavior is consistent with self-image
- Emotional response to performing the behavior is positive
- Confidence in ability to perform the behavior
