A personality measure of Erikson's life stages: the Inventory of Psychosocial Balance.

The development and initial validation of the Inventory of Psychosocial Balance (IPB), designed to assess all eight Eriksonian psychosocial stages, is described. A pool of 208 items that survived a clinical analysis was administered to 528 subjects and then factor analyzed. The resulting eight factors parallel the eight stages and account for 72.34% of the total variance. Subsequent administrations of the IPB to various samples indicate adequate internal consistency and high test-retest reliability; significant correlations with the California Psychological Inventory (CPI) Social Maturity Index; consistent Q-sort portraits of high-scoring and low-scoring women; negligible correlations with test taking response styles, intelligence, and measures of psychopathology; and moderate developmental trends.
