Adaptiveness of Perfectionism?

Can perfectionism be healthy or adaptive?

We believe that perfectionism is not an adaptive or healthy interpersonal or personality style. Although some writers in the field have suggested that there is a healthy form of perfectionism it is not clear that adaptive perfectionism is different from conscientiousness or needing to be excellent. We believe further that needing to be excellent is different from needing to be or needing to appear to be perfect.
