【 摘 要 】

Authors report a study on psychometric properties of Plutchik's test, called Emotions Profile Index (EPI). A new Slovene translation and adaptation of English version of the test, consisting of combinations (pairs) of 12 words reflecting eight different emotional conditions, was prepared and compared to the old one. Both versions as well as the Big Five Questionnaire (BFQ) were administered on the sample of 239 participants. Different statistical analyses were performed examining psychometric features of both versions of EPI. Discriminative power was tested by cluster analysis and analysis of frequency distributions, reliability was studied via internal consistency index and correlation between the two versions, and validity was examined by correlating PIE dimensions with BFQ dimensions and subdimensions, by comparing profiles of groups on both versions of EPI and BFQ and by fitting the theoretical model proposed by Plutchik to the data. Discriminative power of EPI seems to be affected by avoiding (not choosing) the socially desirable expressions in the test, parallel reliability seems to be susceptible to the use of different words (expressions) in the new version of EPI having the same meaning as words in the old version. Dimensions expected to reflect similar constructs in BFQ and EPI do not correlate satisfactory. Data gathered with EPI cannot be fully explained with the model proposed by Plutchik's theory.
