This article is concerned with the effects of social change on the role relationships and adjustment of Chinese Americans. The influences of cultural and social assimilation have undermined the commitment of Chinese youths to traditional cultural norms, and social disequilibrium can be seen within the family as well as outside the home. The changing sex role of females has affected their relationships with their parents and the opposite sex. Chinese vary in the extent to which they have become progressively removed from their parental culture, and the social distances between Chinese with different life styles have segregated them into a variety of disparate groups. Some of the changes in the psychological and social characteristics of the Chinese are examined from empirical studies.
