The measurement of extroversion: A comparison of the Eysenck Personality Inventory and the Eysenck Personality Questionnaire

Rocklin, Thomas, Revelle, William·1981·British Journal of Social Psychology

Abstract

The authors of the Eysenck Personality Inventory (EPI) and the Eysenck Personality Questionnaire (EPQ) have claimed that the extraversion scales contained in the two tests are equivalent. Although scores on the two scales are moderately highly correlated, supplementary analyses suggest that they differ in at least one important respect. While the EPI scale measures extraversion as a reasonable mix of impulsivity and sociability, the EPQ's scale is almost purely a measure of sociability. Recent experimental evidence demonstrates that impulsivity is responsible for several findings previously attributed to extraversion. This evidence raises serious doubt about the usefulness of the EPQ extraversion scale in experimental research on extraversion.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
