Abstract
BACKGROUND: There is considerable interest among personality psychologists in authenticity. To provide researchers with a tool to study dispositional authenticity among speakers of Polish, we created a Polish language version of Wood et al.'s multidimensional measure of authenticity. Wood et al.'s measure has 12 items and measures three constructs: four items for selfalienation; authentic living; and accepting external influence. PARTICIPANTS AND PROCEDURE: Participants were 825 Polish adults (M (age) = 42.7, SD = 15.4; 50% women) who were recruited by a professional survey company. Participants completed the newly developed measure of authenticity, and for validation purposes, they completed measures of Ryff's model of well-being, self-esteem, satisfaction with life, and stress, the same measures used by Wood et al. RESULTS: A confirmatory factor analysis found that the Polish version of the scale had the same three factors as the original measure developed by Wood et al., and the loadings of the items on the factors were consistent with those presented by Wood et al. The three scales of the new measure were reliable. Moreover, relationships between the authenticity scales and the validation measures were similar to those reported by Wood et al. CONCLUSIONS: The present results suggest that our proposed Polish language version of Wood et al.'s multidimensional authenticity scale measures a similar set of constructs to those measured by the original English language scale. Therefore, we believe our new measure should be useful for researchers interested in studying dispositional authenticity among Polish language speakers.
