Which term describes the applicability of study results to routine clinical practice?

• A. Validity
• B. Reliability
• C. Effectiveness
• D. Efficacy

Answer: (C)

This question is about how well study results translate to everyday medical practice. Effectiveness describes how a treatment performs in real-world, routine clinical settings with typical patients, varying adherence, and usual clinical workflows. That practical, real-world impact is what clinicians care about when applying results to day-to-day care. Efficacy, by contrast, refers to how well the treatment works under ideal, controlled conditions with strict protocols and carefully selected participants. Validity and reliability focus on the accuracy and consistency of the measurements within the study, not on how broadly the results apply. So the term that best captures applicability to routine clinical practice is effectiveness.
