Abstract

Purpose: To investigate the dimensionality and psychometric properties of the Schwartz Human Values Scale Short Form included in the European Social Survey (ESS) questionnaire. Method: Greek and Slovenian ESS data of 2002 were used. Each sample was split randomly into two halves and Exploratory Factor Analysis (EFA) was performed on one half-sample in order to assess the construct validity of the scales. The structure was validated by carrying out Confirmatory Factor Analysis (CFA) on the second half. Results: In both countries, EFA resulted in a three-factor solution but the third subscale was found not to be reliable. In the case of Greece, CFA showed acceptable fit for a 16-item model defined by two first-order correlated factors, Openness to change and Self-transcendence. In the case of Slovenia, CFA showed best fit for a 13-item model defined by three first-order correlated factors, Openness to change, Self-transcendence and Self-enhancement. Conclusions: Although our analysis did not confirm the dimensionality of the Schwartz Human Values Scale as proposed in the literature, it did produce two subscales for Greece and three subscales for Slovenia that were reliable and valid. Our results suggest that further research is necessary in each country in order to provide subscales suitable for use in analyses.
