Evolution of the Dynamic Symptoms Model

Area of Science:

• Nursing Science
• Clinical Care Research

Background:

• Conceptual models and theories provide frameworks for understanding phenomena in clinical nursing and interdisciplinary care.
• These models aid in literature reviews, formulating research variables, and identifying research gaps.
• Existing symptom models include the Theory of Symptom Management, Theory of Unpleasant Symptoms, Symptoms Experience Model, and Symptom Experiences in Time Theory.

Purpose of the Study:

• To review existing conceptual models and theories in clinical nursing and interdisciplinary care.
• To highlight the importance of these models in guiding research and identifying knowledge gaps.
• To introduce the National Institutes of Health Symptom Science Model as a recent advancement.

Main Methods:

• Literature review of existing conceptual models and theories in nursing.
• Analysis of the role of these models in research design and literature synthesis.
• Identification and discussion of prominent symptom management and experience models.

Main Results:

• Conceptual models serve as essential tools for organizing knowledge and directing research efforts.
• A range of symptom theories and models have been developed over time to explain symptom phenomena.
• The National Institutes of Health Symptom Science Model represents a contemporary framework for advancing symptom science.

Conclusions:

• Conceptual models are crucial for advancing nursing science and clinical practice by providing explanatory and predictive frameworks.
• The evolution of symptom models reflects a growing understanding of symptom complexity and its management.
• The NIH Symptom Science Model offers a promising direction for future symptom research and intervention development.
