This assessment uses the current nine-item IPIP Positive Expressivity scale attributed to Barchard (2001). The official key contains six positively keyed and three negatively keyed statements. The scales were administered in the adult Eugene–Springfield Community Sample. The official IPIP table reports coefficient alpha of .81 for women (n=432) and .79 for men (n=317). It lists 9 items and gives 10 in parentheses, which the table defines as the original item count before maximizing internal consistency. Those are group-level estimates reported in binary gender categories. The source sample was geographically and demographically limited and is not a current population norm; the coefficients do not establish individual accuracy, stability, cross-cultural equivalence, or predictive usefulness.
Very Inaccurate through Very Accurate receive 1–5 points for the first six positively keyed items. The final three negatively keyed items are reverse scored from 5 to 1. All nine keyed values are summed for a total from 9 to 45. TraitSpring selects less when the keyed average is below 2.5, mixed from 2.5 through 3.5 inclusive, and more above 3.5. With nine integer-scored items, those positions correspond to totals of 9–22, 23–31, and 32–45. They are TraitSpring locations on the possible response range, not source-authored cutoffs, norms, percentiles, or population rankings.
