Briefly Measuring Multifaceted Curiosity: A German and English Brief Measure of 5DCR

With the Five-Dimensional Curiosity-Scale Revised (5DCR), Kashdan et al. (2020) developed the most sophisticated measure of curiosity to date. We validated a brief measure of this instrument, namely, 5DC-S, by reanalyzing two existing samples from Germany (N = 486) and the UK (N = 483). Using the German sample, we reduce the number of facets from six to five and selected the ten most suitable items, out of 24, in a data-driven manner, and this brief measure’s psychometric properties extensively. In the UK sample, we then confirmatorily check the resulting 5DC-S, providing further support for the measure’s factorial structure through statistical modelling and construct validity by widely replicating the nomological network of the original measure. Lastly, we show that 5DC-S is measurement invariant to the highest level across both countries as well as age groups, sex, and education levels. We end on practical implications and future research suggestions.
