ABSTRACT
This chapter provides recommendations on which measures to use and guidance on which decisions researchers have to make when using these measures to capture perfectionism in sport, dance, and exercise. The Hewitt-Flett Multidimensional Perfectionism Scale (HF-MPS) is based on a multidimensional model of perfectionism differentiating three forms of perfectionism: self-oriented, other-oriented, and socially prescribed. The HF-MPS has shown reliability and validity in numerous studies outside sport, dance, and exercise. Mouratidis and Michou, for example, contextualized Personal Standards and Concerns over Mistakes to examine perfectionism in sport, motivation, and coping in junior athletes; and Cumming and Duda contextualized Personal Standards, Concerns over Mistakes, and Doubts about Actions to examine perfectionism in dance, body-related concerns, and psychological health in vocational dance students. The Perfectionism in Sport Scale was developed at about the same time as the Sport-MPS and, like the Sport-MPS, is based on Frost et all's multidimensional model of perfectionism.
