ABSTRACT
This chapter describes the basic propositions of a recently developed framework called the 2 x 2 model of perfectionism. In the 2 x 2 model, perfectionism is operationalize as a personality system composed of two broad dimensions applicable to all individuals: Personal Standards Perfectionism (PSP) and Evaluative Concerns Perfectionism (ECP). The chapter shows that subtypes of perfectionism can be studied within the realm of traditional variable-centered statistical analyses. The 2 x 2 model also differs from the tripartite model with regard to the third subtype of perfectionism. Using both approaches, researchers have started to test and provide empirical support for the four hypotheses of the model in context of sport and dance. Research is still lacking in the field of exercise psychology. Multiple regressions, with and without interaction terms, are covered during basic and advanced training of researchers in psychological sciences and sport sciences.
