Abstract

Aim:

This paper presents a new theoretical model to explain people's diverse responses to therapeutic health technology by characterizing the relationship between technology dependence and health-related quality of life (HRQL).

Introduction:

Technology dependence has been defined as reliance on a variety of devices, drugs and procedures to alleviate or remedy acute or chronic health problems. Health professionals must ensure that these technologies result in positive outcomes for those who must rely on them, while minimizing the potential for unintended consequences. Little research exists to inform health professionals about how dependency on therapeutic technology may affect patient-reported outcomes such as HRQL. Organizing frameworks to focus such research are also limited.

Model:

Generated from the synthesis of three theoretical frameworks and empirical research, the model proposes that attitudes towards technology dependence affect HRQL through a person's illness representations or commonsense beliefs about their illness. Symptom distress, illness history, age and gender also influence the technology dependence and HRQL relationship. Five concepts form the major components of the model: a) attitudes towards technology dependence, b) illness representation, c) symptom distress, d) HRQL and e) illness history.

Conclusion:

The model is proposed as a guide for clinical nursing research into the impact of a wide variety of therapeutic health care interventions on HRQL. Empirical validation of the model is needed to test its generality.

Models of Health Promotion and Illness Prevention II

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 from...

Concepts of Health and Illness

Concepts of Health and Illness

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...

Models of Health Promotion and Illness Prevention I

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...

Dimensions of Health and Illness

Dimensions of Health and Illness

The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

Factors Affecting Illness

Factors Affecting Illness

When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...
