Repertory grids as mental tests: Implications of test theories for grids

Abstract

As repertoy grids are often used in the muking of important decisions about people‘s lives, it seems reasonable to d m n d that the technique accurately reflect the mental structure and processes of the person. This need has not gone unnoticed, either by proponents of the grid technique or its critics, but their calls for psychometric rigor nre couched in terms of reliability and validity, terms that have specific operational meanings, and have been derived from the theories proposed for standnrd psychological tests. This article examines the buses and structures of such theories in the context of repertonj grid data. © 1990 by Hemisphere Publishing Corporation.
