validity and reliability in case study research

Quality of Life Research 2002 11:193–205). In fact, the research strategy that is regularly pursued in content analysis is governed by these traditional criteria of validity and reliability, where. (Scientific Advisory Committee of the Medical Outcomes Trust Assessing health status and quality-of-life instruments: Attributes and review criteria. What is Responsiveness? An instrument’s ability to detect change over time.On the other hand, evaluating validity involves determining whether the instrument measures the correct characteristic. After all, with reliability, you only assess whether the measures are consistent across time, within the instrument, and between observers. 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. Validity is more difficult to evaluate than reliability.Assessing health status and quality-of-life instruments: attributes and review criteria. (Scientific Advisory Committee of the Medical Outcomes Trust. What is Validity? The degree to which an instrument measures what it is supposed to measure. One of the most frequent criticisms associated with the case study approach is its low validity and reliability.The validity, on the other hand, refers to the. For example, if you measure a cup of rice three times, and you get the same result each time, that result is reliable.

When it comes to data analysis, reliability refers to how easily replicable an outcome is. Through this study, the aim is to provide concise and practical study material to help researchers apply case study techniques more robustly. However, in research and testing, reliability and validity are not the same things. A list of references for published validity, reliability and responsiveness studies. explore ways in which the validity and reliability of a case study can be increased, seeking to identify and critically explore the position of several authors on this subject.
