Immigration and mental health: Mexican Americans in the United States

The Hispanic population in the United States continues to expand rapidly du e primarily to a large flow of immigrants from Mexico. Historical observati ons of disadvantage in the immigrant population, when compared to the nativ e population, had helped to shape prevailing theories on immigration and me ntal health. However, data emerging from new research on Mexican Americans have come to challenge the old idea that immigrants are necessarily disadva ntaged. The goal of this article is to review these new studies critically, to draw conclusions concerning the relationship between immigration and ps ychopathology, and to offer potential explanations for the major findings. We review five recent large-scale studies that examined the prevalence of m ental disorders among Mexican-born immigrants and U.S.-born Mexican America ns in the United States. Results of these studies are inconsistent with tra ditional tenets on the relationship among immigration, acculturation, and p sychopathology. They show that Mexico-born immigrants, despite significant socioeconomic disadvantages, have better mental health profiles than do U.S .-born Mexican Americans. Possible explanations for the better mental healt h profile of Mexican immigrants include research artifacts such as selectio n bias, a protective effect of traditional family networks, and a lower set of expectations about what constitutes "success" in America. The elevated rates of psychopathology in U.S.-born Mexican Americans may be related to e asier access to abused substances and an elevated frequency of substance ab use among the U.S.-born.
