This three-sample study focused on changes in four key features of women's
personalities (identity, generativity, confident power, and concern about a
ging) over the course of middle age. Based on women's retrospective and con
current feelings about their lives in their 30s, 40s, and 50s, scales were
developed and validated for the four themes. We found that identity certain
ty, generativity, confident power, and concern about aging all were experie
nced as more prominent in middle age (the 40s) than in early adulthood (the
30s). We also found that these elements of personality were rated even hig
her in the 50s than the 40s. Scores seemed to be a function of age more tha
n historical period or particular experiences in social roles. Scores on id
entity certainty, generativity, and confident power were positively related
to well-being, while concern about aging was negatively related to well-be
ing.
