Which approach best informs the generalizability of study findings to your practice?

• A. Consider whether results apply to your patient population and context.
• B. Apply findings regardless of population.
• C. Assess external validity by comparing population, setting, and outcomes.
• D. Rely only on statistical significance.

Answer: (C)

Generalizability, or external validity, is about whether the study results can apply to your own patients and practice. The strongest way to judge this is to examine how the study’s population, setting, and outcomes compare to your context. If your patients share similar characteristics (age, comorbidities, severity) and your care setting is similar (resources, protocols, follow-up), the findings are more likely to be applicable. Also, ensure the outcomes measured are those that matter in your practice and that the intervention would be feasible in your environment. Simply considering whether the results might apply to your population misses important context about setting and outcomes, and applying findings without regard to these factors risks a mismatch in real-world practice. Relying only on statistical significance tells you about chance vs. real effect but not about whether the effect would occur in your patients or under your usual conditions.
