Models of Health Promotion and Illness Prevention I

2.6K
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...

Concepts of Health and Illness

16.9K
Health is a condition of the body, mind, and spirit where an individual remains free from illness. Similarly, wellness is an active state, including living a lifestyle that promotes physical, mental, and emotional health. Physical health is critical for the overall well-being and can be affected by lifestyle, activity level, diet, and behavior. The highest attainable standard of health is a fundamental and universal human right. Consider Lisa, a fifteen-year-old born with congenital...

Multicompartment Models: Overview

468
Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Models of Health Promotion and Illness Prevention II

2.0K
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...

Model Approaches for Pharmacokinetic Data: Physiological Models

230
Physiological models in pharmacokinetics are instrumental in understanding the distribution and elimination of drugs within the body. These models describe the drug concentration within target organs, influenced by factors such as drug uptake, tissue volume, and blood flow. Drug uptake is governed by the partition coefficient, which signifies the drug concentration ratio in tissue to that in the blood. The blood flow rate to a specific tissue is expressed as Qt, and the rate of change in tissue...

Pharmacokinetic Models: Overview01:20

Pharmacokinetic Models: Overview

1.8K
Pharmacokinetic models utilize mathematical analysis to achieve a detailed quantitative understanding of a drug's life cycle within the body. They are instrumental in simulating a drug's pharmacokinetic parameters, predicting drug concentrations over time, optimizing dosage regimens, linking concentrations with pharmacologic activity, and estimating potential toxicity.
There are three primary types of models: empirical, compartment, and physiological. Empirical models, with minimal...

Area of Science:

  • Human-Computer Interaction
  • Digital Health
  • Mobile Health (mHealth)

Background:

  • Understanding user mental models is crucial for effective mobile health (mHealth) app design.
  • Existing research often overlooks the complexity and multimodal nature of these mental models.

Purpose of the Study:

  • To describe the shared mental models of mHealth app users.
  • To uncover the complexity and influencing factors of these mental models.

Main Methods:

  • Qualitative structured interviews were conducted with users of mobile health applications.
  • Analysis focused on identifying common themes and patterns in user perceptions.

Main Results:

  • Users' mental models for mHealth apps are complex and multimodal, with distinct dimensions for aesthetics and craftsmanship.
  • These models are influenced by experiences across the broader mobile app landscape, not just health apps.
  • Prototypical design components, common to non-health apps, are present in mHealth mental models.

Conclusions:

  • mHealth app designers should consider prototypical features and trends from the wider app ecosystem.
  • Designers need to balance the multidimensional and often conflicting aspects of user mental models.
  • Incorporating salient features and aligning with broader app trends can enhance user engagement and app effectiveness.
