Measurement Properties: Validity, Reliability, and Responsiveness
A list of references for published validity, reliability and responsiveness studies.
- What is Validity? The degree to which an instrument measures what it is supposed to measure. (Scientific Advisory Committee of the Medical Outcomes Trust; Assessing health status and quality-of-life instruments: Attributes and review criteria. Quality of Life Research, 2002;11:193–205).
- Validity Studies
- What is Reliability? The degree to which an instrument can produce consistent results, and consistent results on different occasions, when there is no evidence of change. (Bowling A. Measuring Disease 2001; 2nd Edition. UK: Open University Press p. 20).
- Reliability Studies
- What is Responsiveness? An instrument's ability to detect change over time. (Scientific Advisory Committee of the Medical Outcomes Trust; Assessing health status and quality-of-life instruments: Attributes and review criteria. Quality of Life Research 2002;11:193–205).
