Development and Validation of the Tehran Multidimensional Perfectionism Scale

This paper presents an account of the development, reliability, and validity of the 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 the Tehran Multidimensional Perfectionism Scale (TMPS), the Inventory of Interpersonal Problems (IIP), the Mental Health Inventory (MHI), and Neuroticism and Extraversion subscales of the NEOPI-R. Test-retest reliability and internal consistency of the IIP were examined at satisfactory levels. Concurrent validity of the TMPS was calculated according to correlation coefficients of the scores on the TMPS and scores of the IIP, MHI, and NEOPI-R. All correlations were statistically significant.
