This paper describes the development and validation of a pairwise comparison scale for user experience (UX) evaluations with preschoolers. More particularly, the dimensionality, reliability and validity of the scale are discussed. The results of three experiments among almost 170 preschoolers show that user experience cannot be measured quantitatively as a multi-dimensional construct. In contrast, preschoolers' UX should be measured directly as a one-dimensional higher order construct. This one-dimensional scale encompassing five general items proved to be internally consistent and valid providing evidence of a solid theory-based instrument to measure UX with preschoolers.
