Which type of reliability assesses consistency across different observers evaluating the same phenomenon?

• A. Intra-observer reliability
• B. Inter-observer reliability
• C. Test-retest reliability
• D. Reliability

Answer: (B)

This question is about how consistent measurements are when more than one person is making the assessment. Inter-observer reliability measures the agreement or consistency between different observers or raters who evaluate the same phenomenon. If two clinicians rate the same patient’s pain on a scale and their scores line up closely, the inter-observer reliability is high, indicating the rating is reliable across observers. Intra-observer reliability would involve the same person rating consistently across different times. Test-retest reliability deals with the stability of a measure over time when the same test is repeated. The general term reliability is too broad and doesn’t specify the observer dimension.
