This report discusses identity themes that emerged in a longitudinal (1977-1981) study of identity, ego, and career development patterns among immigrant adolescents and young adults in Boston, Massachusetts. Qualitative data, which were collected from journals that the subjects kept, and from semi-structured interviews, revealed the subjects' feelings about being in the United States; interpersonal relationships; outlooks on life; and perceptions of themselves as young adults. Three major themes were derived from analysis of the data. One theme, "sense of belonging versus enstrangement," reflected the youths' initial feelings of alienation from American society (because of their different cultural background and experiences with discrimination), which gave way to a sense of belonging as the way of life became more familiar, new friendships were forged, and citizenship status was attained. A second theme, "identification with the primary group and cultural values," indicated the strong influence of family and traditional values on the subjects' career choices, friendships, and philosophies of life. A third theme, "personal relations," emphasized the importance of personal relationships in the search for self. The data suggested that immigrant youths combined new and familiar cultural elements to reach a new sense of balance in the search for identity. (Author/MJL)
