Final answer:
The Health Belief Model (B) is the theory that explains how influencing four sets of beliefs can affect health behaviors. It emphasizes individual perceptions of susceptibility, severity of health issues, benefits, and barriers to change, and is supported by the work of Albert Bandura in the field of health psychology.
Step-by-step explanation:
The model or theory that helps you understand how you can affect health behaviors by influencing four sets of beliefs is known as the Health Belief Model (B). This model is grounded in the understanding that a person's beliefs about health problems, perceived benefits of action and barriers to action, and self-efficacy can explain engagement (or lack of engagement) in health-promoting behavior. It encompasses strategies to address the individual's perceived susceptibility, perceived severity, perceived benefits, and perceived barriers to taking action, all of which affect a person's willingness and readiness to change behaviors.
Albert Bandura, a key figure in health psychology, contributed significantly to our understanding of how beliefs influence behavior. His work on self-efficacy, as part of the broader Social Cognitive Theory, emphasizes the role of cognitive processes in behavior change. The Health Belief Model aligns well with the biopsychosocial model by including psychological factors in the process of health behavior change.
