This chapter provides a synopsis of research on where multidimensional perfectionism “fits” within the broader framework of contemporary personality theory. Focusing on Hewitt and Flett’s (1991) model of perfectionism--differentiating self-oriented, other-oriented, and socially prescribed perfectionism--the chapter presents a summary and critical discussion of how multidimensional perfectionism relates to the dimensions and facets of two major structural models of personality (the five-factor model and the HEXACO model) and one neuropsychological model of personality (reinforcement sensitivity theory). Implications of the findings for multidimensional theories and models of perfectionism, as well as future perfectionism research, are discussed
