If multiple clinicians assess the same patients with the same test, this scenario assesses which reliability?

• A. Intrarater reliability
• B. Interrater reliability
• C. Test-retest reliability
• D. Construct validity

Answer: (B)

When multiple clinicians assess the same patients with the same test, you’re looking at how consistently different raters judge the results. That is interrater reliability. It measures agreement across different evaluators, which matters when multiple clinicians influence a patient’s diagnosis or treatment based on the same test. If the same clinician repeated the assessment, that would be intrarater reliability, focusing on one person’s consistency. If you were to administer the test at different times to see if results stay the same, that’s test-retest reliability, addressing stability over time. Construct validity is about whether the test actually measures the intended concept, not about the agreement between raters. In practice, interrater reliability can be quantified with statistics like Cohen’s kappa for categorical judgments or the intraclass correlation coefficient for continuous scores.
