The Multidimensional Perfectionism Scale: Reliability, validity, and psychometric properties in psychiatric samples.

Abstract

Previous perfectionism measures have not been evaluated for use with clinical samples. This research examined the psychometric properties of the Multidimensional Perfectionism Scale (MPS), a 45-hem measure of self-oriented, other-oriented, and socially prescribed perfectionism. Study 1 provided normative data for various patient groups and demonstrated the stability of the MPS subscales in psychiatric patients. Study 2 showed that the MPS subscales have adequate concurrent validity, are not influenced by response biases, and that the items require a Grade 6-7 reading level. Overall, the MPS appears to be a useful measure for individuals with various clinical disorders.
