Generalizability
Generalizability refers to the extent to which the results or findings of a study can be applied beyond the specific sample, setting, or context in which the study was conducted.
🧠 Definition
Generalizability is the degree to which study conclusions are valid for populations, environments, or clinical scenarios outside the original research conditions. It determines the external validity of a study.
🔍 Key Elements
- Sample size and diversity – More diverse and representative samples improve generalizability.
- Study design – Randomization and real-world settings increase generalizability.
- Contextual relevance – Findings must align with the target population’s characteristics, healthcare systems, or clinical practices.
⚠️ Threats to Generalizability
- Use of cadaveric or animal models
- Highly specialized centers or surgeons
- Small or homogeneous samples
- Studies done in non-clinical or artificial settings
