The relationship between psychosocial development and ego identity was explored among a group of 29 married women, 21-59 years old. After being interviewed, subjects were assigned to one of four categories of identity status, based on their statements regarding decision-making and commitment. There were significant differences between identity categories in resolution of all psychosocial stages in the Inventory of Psychosocial Development (IPD). Women in the Identity Achievement category (showing the most "active" level of decision-making and subsequent commitment) scored significantly higher than women in the other categories on all IPD stages except intimacy and trust. These differences provide empirical support for Erickson's theory of psychosocial development as well as some discriminant validity for the IPD. (Author/CS)
