Ego-strength revised: a comparison of the MMPI-2 and MMPI-1 versions of the Barron Ego-strength scale.
This study evaluated the equivalence of the original MMPI and the shortened MMPI-2 versions of the Barron (1953) Ego-strength scale, an important research scale. Three hundred fifty-five subjects took the MMPI-2 and the 16 MMPI-1 items dropped from the original scale. The omitted items appear to contribute little to the original scale. The revised version compares favorably with the old in terms of internal consistency, and the two versions are highly intercorrelated. Confirmatory Factor Analysis indicates that four of Stein and Chu's (1967) five groupings of the original items provide a reasonably good fit for the MMPI-2 as well. Compared to the original, the new version was slightly more correlated with other paper-and-pencil measures of psychological health and well-being.
