How is evidence defined in evidence-based practice?

• A. An empirical observation verifiable by observation or experience, whether or not systematically collected
• B. A personal belief not supported by data
• C. A theoretical deduction from philosophy
• D. A tradition passed down without testing

Answer: (A)

Evidence-based practice relies on information that comes from observable data that can be verified through observation or experience, whether or not it was collected through formal, systematic methods. The crucial point is that evidence is something you can check and confirm with real-world data, not just personal opinion or speculation. In practice, this means an observation that a treatment appears to help a patient, if it can be verified across cases, counts as evidence. Systematic data collection strengthens this, but the core idea remains verifiability through observation or experience. Personal beliefs not supported by data are not evidence, theoretical deductions from philosophy aren’t empirical evidence, and traditions that haven’t been tested aren’t evidence either.
