Posttraumatic stress disorder among ethnoracial minorities in the United States

Because ethnoracial minorities are a growing part of the U.S. population yet are underrepresented in the psychopathology literature, we reviewed the evidence for differences in prevalence and treatment of posttraumatic stress disorder (PTSD) in African Americans, Latino Americans, Asian and Pacific Islander Americans, and American Indians. With respect to prevalence, Latinos were most consistently found to have higher PTSD rates than their European American counterparts. Other groups also showed differences that were mostly explained by differences in trauma exposure. Many prevalence rates were varied by subgroup within the larger ethnoracial group, thereby limiting broad generalizations about group differences. Regarding service utilization, some studies of veterans found lower utilization among some minority groups, but community-based epidemiological studies following a traumatic event found no differences. Finally, in terms of treatment, the literature contained many recommendations for culturally sensitive interventions but little empirical evidence supporting or refuting such treatments. Taken together, the literature hints at many important sources of ethnoracial variation but raises more questions than it has answered. The article ends with recommendations to advance work in this important area.
