If the same clinician can reproduce results across multiple tests, which reliability?

• A. Intraobserver reliability
• B. Interobserver reliability
• C. Specificity
• D. Sensitivity

Answer: (A)

This question is about consistency of measurements when the same clinician repeats them. When one clinician can reproduce the same results across multiple trials, it demonstrates high intraobserver reliability (also called intrarater reliability). It shows that the measurement process is stable for that observer over time. Interobserver reliability would involve agreement between different clinicians, not one person repeating tests. Specificity and sensitivity describe a test’s accuracy relative to a reference standard, not its repeatability. For example, a physio measuring a joint angle across several sessions with the same rater and getting similar values shows high intraobserver reliability.
