This assessment uses Johnson’s (2014) four-item IPIP-NEO-120 Assertiveness (E3) facet. Here, assertiveness refers narrowly to taking charge and trying to lead. The official IPIP key reports coefficient alpha of .85 in a self-selected Internet sample (n=619,150). A separate Eugene-Springfield community sample (n=757) reported alpha of .76 and an uncorrected correlation of .73 with the corresponding comparison facet. These group-level estimates vary by sample and do not establish the precision or stability of one individual result. In Johnson’s factor analysis of the 120-item inventory, this E3 scale loaded more strongly on a Conscientiousness component than on the expected Extraversion component. Both sources administered these items within a much longer inventory, while TraitSpring presents the four-item facet by itself.
Very Inaccurate through Very Accurate receive 1–5 points. The first three items are scored directly; the fourth is reverse scored from 5 to 1. The four keyed values are summed for a total from 4 to 20.
