Ethics in Research01:56

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.
Concepts of Health and Illness01:29

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...
Dimensions of Health and Illness01:21

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.
Models of Health Promotion and Illness Prevention II01:18

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...
Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches01:23

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast, controlled...
Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

    Summary

    Rethinking research rigor is crucial. Current narrow definitions may cause errors, but an expanded view can improve scientific integrity and address health issues effectively.

    Area of Science:

    • Research Methodology
    • Scientific Integrity
    • Health Research

    Background:

    • The prevailing conceptualization of research rigor is often too narrow.
    • This limited view may contribute to common errors in the research process.
    • Existing frameworks may not fully capture the complexities of scientific inquiry.

    Purpose of the Study:

    • To present an expanded conceptualization of research rigor.
    • To discuss the implications of this expanded view for scientific practice.
    • To highlight how a broader understanding of rigor can improve health research.

    Main Methods:

    • Conceptual analysis of research methodology.
    • Exploration of researcher's decision-making processes.
    • Application of an expanded rigor framework to health issues.

    Main Results:

    • Current definitions of rigor are insufficient.
    • An expanded conceptualization offers a more comprehensive approach.
    • This broadened perspective can mitigate research errors.
    • Implications for critical health issue research are significant.

    Conclusions:

    • A narrow focus on methods over researcher choices limits scientific rigor.
    • Expanding the concept of rigor is essential for improving research quality.
    • This enhanced understanding is vital for advancing critical health research and reducing errors.
