Abstract
In this article, we introduce Item Pool Visualization. It is an illustration system that locates items and item pools (scales) from
multiple psychological instruments regarding their commonality and distinguishability along several dimensions of nested radar
charts. The application of Item Pool Visualization creates illustrations that represent different item pools by different circles
that do not overlap. Item Pool Visualization illustrates a comparison of different structural equation models that are estimated
with the same data. It combines the advantages of general and correlated factor models when evaluating psychological
instruments. Furthermore, in contrast to other visualization methods, Item Pool Visualization provides an empirically driven
categorization of psychological constructs and their subconcepts (facets) that is suited to provide professionals with help in
comparing psychometric constructs, questionnaires, and selecting tests.
