All participants were asked to complete Tehran Multidimensional Perfectionism Scale (TMPS), the Inventory of Interpersonal Problems (IIP), Neuroticism and Extraversion subscales of the NEOPI-R, and the Mental Health Inventory (MHI). Results supported three-factor structure, convergent and discriminant validity, internal consistency, and test-retest reliability of the TMPS.
