Question 1

Individual-level theories

Answer 1

• Identification of determinants of health behaviors
• Design and evaluation of health behavior change interventions

Question 2

Health Belief Model (HBM)

Answer 2

• perceived likelihood and severity of a threat as well as the perceived benefits and barriers of taking action
• Cues to action
  - factors that instigate action
• Self-efficacy- belife that someone can successfully exicute behavior

Question 3

Theory of Planned Behavior (TPB)
Theory of Reasoned Action (TRA)
Integrated Behavioral Model (IBM)

Answer 3

• These theories provide a systematic method for identifying issues important to decisions about performing specific behaviors
• All three assume that attitudes, subjective norms, and perceived behavioral control affect behavioral intentions, which are linked to behavior
• Many attitudes are modifiable and therefore ideal targets for intervention

Question 4

Theory of Planned Behavior (TPB)
Theory of Reasoned Action (TRA)
Integrated Behavioral Model (IBM)

Answer 4

• Behavioral intention measures should closely match the target behavior
  - Measurement requires precision and detailed work

-Longitudinal studies have found strong intention-behavior relationships
-Rigorous experimental studies have found significant small to moderate effects
-However, intentions do not always translate to behavior and should not be used as a proxy for behavior or behavior change

Question 5

The Transtheoretical Model (TTM)

Answer 5

• Posits that people are in different stages of readiness to make health behavior changes
• The TTM is one of the most widely used behavior change models
• The inclusion of processes of change is a strength of the TTM
