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. CFA showed better fit for the model defined by two first-order correlated factors - Openness to change/Self-enhancement and Self-transcendence/Conservation – which provided reliable and valid subscales.
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 that were both reliable and valid. Our results suggest that further research is necessary in each country and each round of the ESS in order to provide subscales suitable for use in analyses.
