Further validation of the questionnaire for eudaimonic well-being (QEWB)

Abstract

The aim of this study was to explore the structural and external validity of the recently developed Questionnaire for Eudaimonic Well-Being (QEWB), scrutinising the parcelling approach used by Waterman and colleagues to confirm the unidimensional structure of the scale. A multicultural South African student sample ( n = 325) was used. Parcel- and item-level confirmatory factor analysis and item-level exploratory factor analysis were conducted to explore the scale’s structural validity. External validity was examined via attenuation corrected correlations with scores on criterion measures. On parcel-level a one-dimensional structure fitted well, but since the assumption of unidimensional parcels was violated, the use of parcelling was contra-indicated. Item-level analyses revealed a multidimensional factor structure. The scale showed good convergent and discriminant validity. The QEWB shows potential for future use, given that the multidimensionality of the scale is acknowledged. Some items may need revision.
