Abstract :

the present study aimed to investigate the psychometric properties of the Multidimensional Perfectionism Cognitions Inventory-English (MPCI-E; Kabori, 2006) among Iranian students. Three hundred university students (156 males, 144 females) completed the MPCI-E and the Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988). The exploratory and confirmatory factor analyses and internal consistency were used to assess factorial validity and reliability of the MPCIE, respectively. The divergent validity of the MPCI-E were assessed through correlations between MPCI-E scales and past-week positive and negative affect. The results of principal component analysis (PC) and oblique rotation indicated that the MPCI-E consisted of three factors: personal standards, concern over mistakes, and pursuit of perfection. Goodness-of-fit indices of confirmatory factor analysis confirmed the three extracted factors. A differential pattern of significant correlations between the MPCI-E and positive and negative affect demonstrated divergent validity of the MPCI-E. Internal consistencies of the MPCI-E subscales were good. In sum, these findings provided evidence for the validity and reliability of the MPCI-E as a multidimensional measure of perfectionism cognitions in Iranian students.
