What distinguishes a conceptual model from a theory?

A conceptual model is characterized by its level of abstraction, which is higher than that of a theory. Conceptual models provide a broad framework that offers a way to visualize and understand complex phenomena, often without detailing specific relationships between variables or providing testable predictions. They often serve as more general guides to thinking about a particular area of interest and help to inform the development of more focused theories.

In contrast, theories tend to be more specific and detailed, outlining particular relationships, variables, and mechanisms. They are formulated based on empirical evidence and aim to explain, predict, and guide practice in a more concrete manner. Theories typically include hypotheses that can be tested, making them more grounded in evidence as compared to the broader, more abstract nature of conceptual models.

Recognizing this distinction is crucial for understanding the role each plays in nursing practice and research, where models may guide theoretical development and theoretical constructs may eventually shape practical applications.
