Acculturation, the process whereby immigrants change their behavior and attitudes toward those of the host society, is a fundamental part of migration-induced adaptations to new sociocultural environments. A rapidly expanding research literature on acculturation has accompanied the growth of international migrations. In response to the need to integrate the growing literature on acculturation and mental health status among Hispanics in the United States, and to identify points of convergence and new directions for research, 30 publications were examined. Points of convergence are identified, as are problems and limitations. The research needs new directions, proceeding from but not constricted by the assumptions and procedures in the work already done.
