Models of Health Promotion and Illness Prevention II01:18

Models of Health Promotion and Illness Prevention II

2.2K
The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Models of Health Promotion and Illness Prevention I

3.0K
A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Area of Science:

  • Social Psychology
  • Health Behavior Research
  • Behavioral Science

Background:

  • Normative messages are known to influence intentions toward physical activity.
  • Understanding the specific impact of positive versus negative normative messages is crucial for designing effective health interventions.
  • The Model of Goal-Directed Behavior with Descriptive Norms (MGDB+DNs) provides a framework for examining these influences.

Purpose of the Study:

  • To investigate how positive and negative normative messages affect physical activity intention.
  • To compare the influence of these messages on constructs within the MGDB+DNs framework.
  • To explore the psychological mechanisms underlying these effects across different cultural contexts.

Main Methods:

  • An experimental design was employed with young adults (n=1,200) aged 16-24 in Bulgaria, Croatia, and Romania.
  • Participants were exposed to either positive or negative normative messages, or a control condition.
  • Data were collected on demographics, physical activity levels, and MGDB+DNs constructs via questionnaires.

Main Results:

  • Exposure to negative normative messages significantly strengthened participants' attitudes towards physical activity (p=.003).
  • Exposure to positive normative messages led to significantly higher positive anticipated emotions (p=.005).
  • The findings indicate differential effects of message valence on specific MGDB+DNs components.

Conclusions:

  • Positive normative messages align with conformity theories, enhancing positive emotions related to social norms.
  • Negative normative messages appear to influence attitudes through mechanisms related to social identity and deviance regulation.
  • Tailoring normative message content based on psychological principles can effectively shape physical activity intentions.
