An Investigation of Psychometric Properties of Perfectionism Inventory in Iranian Sample

This study was an attempt to investigate the psychometric properties of the Perfectionism Inventory (Hill, Huelsman, Furr, Kibler, Vicente, & Kennedy, 2004) in a sample of 512 Iranian state university students. Results show internal consistency of scores on total scale (.926) and all of subscales (.751 to .913). Exploratory Factor Analysis using a varimax rotation suggested only 6 underlying subscales instead of 8 subscales, reported by hill & et al. (2004), including: Interpersonal Sensitivity (IS), Striving for Excellence (SE), Organization (O), Perceived Parental Pressure (PPP), Planfulness (P), and High Standards for Others (HSO). Furthermore, test-retest reliability for PI over a month interval was acceptable (r=.736, n=50, p<.001); moreover, the PI scales revealed adequate convergent validity with Frost Multidimensional Perfectionism Scale (1990) (r=.741, n=59, p<.0005).
