A model of cumulative racial-ethnic trauma among Americans of Middle Eastern and North African (MENA) descent.

Americans of Middle Eastern and North African (MENA) descent in the United States have been historically understudied, in part due to limitations of racial classification systems that typically include MENA under the broad umbrella of White. As a result, enormous gaps in knowledge about health and mental health disparities exist, with broad public health significance. In particular, there is an urgent need to attend more specifically to MENA Americans' experiences of cumulative racial-ethnic trauma, which occurs at every level of their social ecologies.
