This isn't a new study, but it popped up in my news alerts, and I thought it was worth sharing.
According to a study published in 2006 by the journal Psychiatry,"Hispanics as a population may be more prone to the development of PTSD." The study found that trauma was intensified by the addition of racial discrimination and the loss of cultural social networks that might have otherwise provided some relief mechanism.
It's this loss of cultural, familial and religious networks (a situation that all immigrants may find themselves in) that makes this study particularly relevant. As the authors write, "the Latino population continues to grow at a pace that far exceeds the capability of both current Latino/bilingual psychiatrists and the number of Latinos in the mental health provider pipeline."
