Self-ratings and the Eysenck Personality Inventory (EPI).

An attempt was made to assess the relationships between self-ratings and psychometric (EPI) estimates on the dimensions of extraversion and neuroticism. Ninety-five individuals served as Ss. The correlations between self-ratings and EPI estimates achieved high significance on both dimensions. Contrary to earlier suggestions (Bem & Allen, 1974), ratings of behavioral variability on the respective dimensions failed to produce a significant moderating effect. However, a tentative trend was observed for cross-procedural comparability (between self-ratings and the EPI) to be higher near the midpoints of the respective distributions. A factor contributory to this was a central regressive tendency (noted at both poles on both dimensions and for both sources of estimation), whereby an extreme estimate from one source was associated with a less extreme estimate from the other.
