Validity and Kane's framework
Cook, D. A., et al. (2015). "A contemporary approach to validity arguments: a practical guide to Kane's framework." Med Educ 49(6): 560-575.
Conclusion:
"Validation is not an endpoint but a process
"Validation ideally begins with a clear statement of the proposed interpretation and use (decision), and continues with a carefully planned interpretation/use argument that defines key claims and assumptions
"educators should focus on the weakest links in the chain of inference.
"implications and associated decisions are ultimately the most important inferences in the validity argument"
Validation is central to medical education. "we require evidence to support the validity of our decisions. The process of collecting and interpreting validity evidence is called "validation""
Validation has changed and evolved over time
Kane's framework (does not specify order, but does seem to flow logically as follows)
Define the proposed use
Scoring inference
Generalisation inference
Extrapolation inference
Implication inference
