Eudaimonic well-being (EWB) has been defined as the positive psychological functioning deriving from the development of one’s best potentials in accordance with one’s true self. The main aim of this study was to investigate the psychometric properties of the Questionnaire for Eudaimonic Well-Being (QEWB; Waterman et al., 2010) within the theoretical framework of Rasch models. One thousand two hundred and five Italian adults (age 18-60 years) completed the Italian version of the QEWB, along with the Italian versions of other two well-being scales. Results showed that the QEWB provides a reliable and valid measure of EWB. However, it might be not adequate for measuring the highest levels of EWB. Furthermore, the item measures were invariant across gender but not across age. The theoretical and empirical implications of the results are discussed.

Abstract
Eudaimonic well-being (EWB) has been defined as the positive psychological functioning deriving from the development of one’s best potentials in accordance with one’s true self. The main aim of this study was to investigate the psychometric properties of the Questionnaire for Eudaimonic Well-Being (QEWB; Waterman et al., 2010) within the theoretical framework of Rasch models. One thousand two hundred and five Italian adults (age 18-60 years) completed the Italian version of the QEWB, along with the Italian versions of other two well-being scales. Results showed that the QEWB provides a reliable and valid measure of EWB. However, it might be not adequate for measuring the highest levels of EWB. Furthermore, the item measures were invariant across gender but not across age. The theoretical and empirical implications of the results are discussed.
