Detailed write-up pending
A full, citation-backed scientific write-up for this scale — overview, clinical use, and psychometrics in the voice of a dissertation "Measures" section — has not yet been authored. To honor the platform's no-fabricated-sources rule, this page currently shows only the verified registry facts above (item count, structure, scoring, and any published norms). No validity coefficients, reliability figures, or citations are shown here that cannot be traced to a named source; the authored write-up will be added once its sources have been read and recorded in the plan-integrity file.

Norms computed from the Eugene-Springfield Community Sample (ESCS) — Lewis R. Goldberg’s adult community panel from Eugene and Springfield, Oregon (Harvard Dataverse, doi:10.7910/DVN/UF52WY). This is a community sample and is NOT nationally representative. The mean, standard deviation, reference N and Cronbach’s α were computed directly from the raw IPIP item-level responses on THIS scale’s exact item set and reverse-keying (complete cases); reference N varies by scale and is shown with each scale below. The confidence range uses the standard error of measurement (SEM = SD·√(1−α)) from that computed α.
