A Validity Network Schema.
Brinberg, David; McGrath, Joseph E.
Numerous forms and meanings of validity have been developed to provide researchers with the opportunity to assess the many potential sources of ambiguity that exist in any research finding. A Validity Network Schema (VNS) developed by Brinberg & McGrath (1982) is extended and elaborated in order to describe the components of the research process and their interrelations, and draw out some implications of the schema for the acquisition of knowledge. VNS describes research as a three-stage process, whose outcome is some structural combination of concepts, methods, and substantive events. In stage 1, researchers develop, clarify, and select elements and relations from the three basic domains--conceptualization, methodological, and substantive. Stage 2, the research study proper, involves two steps: the researcher combines elements and relations from two of the three domains to form an intermediate structure; and the researcher integrates that structure with the elements and relations from the third domain. Stage 3 of the research process involves the reduction of uncertainty associated with the findings of Stage 2 by exploring the range of respondents, events, contexts, methods, and concepts over which the stage 2 results do and do not hold. In stage 3, validity takes on the meaning of robustness and generalizability. (PN)
