The Role of Generalizability in Validity.
Kane, Michael
The relationship between generalizability and validity is explained, making four important points. The first is that generalizability coefficients provide upper bounds on validity. The second point is that generalization is one step in most interpretive arguments, and therefore, generalizability is a necessary condition for the validity of these interpretations. It is also noted that the interpretive argument determines the appropriate estimate of generalizability. The fourth point is that generalizability provides justification for the syntactical content of construct labels. From each of these four perspectives, generalizability can be seen as a necessary, but not sufficient, condition for validity. The invariance assumptions are an integral part of validity, and standard errors and G coefficients quantify, in different ways, how well the invariance assumptions hold. (SLD)
