How is a concept defined in theory terms?

• A. Set of interrelated ideas that are building blocks of theory.
• B. A single observed event.
• C. A concrete procedure for clinical practice.
• D. A numerical measurement.

Answer: (A)

A concept in theory terms is an abstract set of interrelated ideas that serves as a building block for a theory. It’s not a single observed event, nor a concrete clinical procedure, nor a numerical measurement. Concepts organize thinking about how and why phenomena occur, and they link with other concepts to form explanations and predictions. In health promotion, for example, constructs like self-efficacy or perceived susceptibility function as concepts that connect with other ideas to create a coherent theoretical framework. By defining and relating these concepts, researchers can test hypotheses and understand how different factors influence behaviors, rather than just describing what was observed or how a practice is carried out.
