Measuring the Four Higher-Order Values in Schwartz's Theory: Validation of a 17-Item Inventory.

ABSTRACT

Schwartz's theory of basic human values is the dominant framework for assessing values. One of its strengths is that it allows for different levels of analysis. The 10 basic values can be reliably assigned to four higher-order dimensions Openness to Change, Conservation, Self-Transcendence, and Self-Enhancement. In this paper, we examined the psychometric properties of the Higher-Order-Value Scale-17 (HOVS17), an inventory that economically assesses these higher-order values. We analyzed data from the GESIS Panel, an ongoing large-scale probability-based panel study that fields HOVS17 annually since 2013 and for which HOVS17 was originally developed. We found HOVS17 to have satisfactory psychometric properties. The 17 items were located in the two-dimensional multi-dimensional scaling (MDS) space as hypothesized. All four subscales were unidimensional, showed good fit when modeled as reflective latent variables, and had acceptable reliabilities as well as one-year test-retest stabilities (.65 to .69). The subscales correlated in theoretically plausible ways with a wide range of correlates and criteria, such as personality traits and well-being. This demonstrates that HOVS17 provides a sound basis for studying the development, precursors, and consequences of the higher-order values in the GESIS Panel and in future surveys that adopt HOVS17. We also discuss suggestions for further improvements of the inventory.
