To study similarities and differences in personality across historical
periods, ego identity patterns, assessed by Q-sort prototypes, were c
ompared in longitudinal samples of midlife women who had been young ad
ults in the 1950s, early 1960s, and late 1960s. Identity pattern had s
imilar relationships across sample with vector dimensions of the Calif
ornia Psychological Inventory but was related to work and family outco
mes only in the younger cohorts, whose lives were less restricted. Wom
en with the achieved-foreclosed pattern were more alike across cohort
than women with the achieved-moratorium pattern. Among the latter, ind
ependence and high aspirations were salient features of the younger co
horts, whereas interest in motives of self and others were salient in
the older cohort.
