Development and Validation of Tehran Multidimensional Perfectionism Scale

This paper presents an account of the development, reliability, and validity of Tehran Multidimensional Perfectionism Scale. Five hundred students from the University of Tehran (300 females, 200 males) were included in this study. 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. It was concluded that the TMPS is a reliable and valid scale to measure multidimensional perfectionism in Iranian population.
