Abstract

Multidimensional Scaling (MDS) has been a central tool of psychological research into value structure for more than two decades. MDS is usually applied in an exploratory way because strict confirmatory analyses are still difficult to realize, due to the manifold problems of how to impose regional constraints on MDS solutions. “Weak confirmatory approaches” (Borg & Staufenbiel, 2007) which use a theory-based starting configuration could be an acceptable compromise. In this paper, we outline how such a configuration can be derived from Schwartz’s (1992, p. 14) original model, which is characterized by a strict circular structure. Such a “parsimonious” structure seems particularly suited for multi-method studies. We also apply this configuration to the Spanish value data from the first three rounds of the European Social Survey to illustrate the procedure. Finally, we show how to test whether and to what extent regional adjustments of single items affect the overall fit of the respective MDS solution.
