What are the two types of theories, and which was used for the health promotion project?

• A. Grand theory and mid-range theory; used the mid-range theory.
• B. Grand theory and micro theory; used the micro theory.
• C. Mid-range theory and empirical theory; used the empirical theory.
• D. Grand theory and macro theory; used the macro theory.

Answer: (A)

The idea being tested is how theories are scoped and applied in health promotion. Grand theories are broad, abstract frameworks that explain wide aspects of nursing phenomena but don’t easily translate into specific program components. Mid-range theories sit in the middle: they focus on more defined phenomena, populations, or settings, and they offer testable propositions and constructs that can guide intervention design and evaluation. For a health promotion project, a mid-range theory is typically used because it provides concrete guidance that can be applied in real-world settings and measured in outcomes. Therefore, the best choice identifies grand theory and mid-range theory, with the project actually using the mid-range theory, which aligns with the need for practical, testable guidance. The other pairings mix less common or less applicable categories for guiding a health promotion intervention.
