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.
