Many previous studies on human values reported problems with measurement invariance of values measured by PVQ (e.g. Davidov, Schmidt & Schwartz, 2008). Recently Schwartz et al. (2012) proposed a refinement of the value theory and a new questionnaire (PVQ-5x) to measure 19 more narrowly defined values. We test the measurement invariance properties of the PVQ-5x across eight countries (Finland, Germany, Israel, Italy, New Zealand, Poland, Portugal and Switzerland). Two types of analysis were performed: the first one assuming the Likert-scale used in PVQ-5x as continuous and the second one accounting for ordinality of the Likert-scale. Configural invariance is established for all 19 values measured by PVQ-5x. Metric invariance is established for all values (with some exceptions for single countries). Scalar measurement invariance is supported for the following ten values across nearly all countries: benevolence caring, universalism tolerance, universalism concern, universalism nature, hedonism, power dominance, power resources, and security personal. Both analyses lead to the same conclusion: Measurement invariance properties of the new PVQ is significantly better than the properties of the previous PVQ version.
