Research has suggested that African American and Latino adults may develop posttraumatic stress disorder (PTSD) at higher rates than White adults, and that the clinical course of PTSD in these minority groups is poor. One factor that may contribute to higher prevalence and poorer outcome in these groups are sociocultural factors and racial stressors, such as experiences with discrimination. To date, however, no research has explored the relationship between experiences with discrimination and risk for PTSD, and very little research has examined the course of illness for PTSD in African Americans and Latino samples. The present study examined these variables in the only longitudinal clinical sample of 139 Latino and 152 African American adults with anxiety disorders, the Harvard/Brown Anxiety Research Project – Phase II (HARP-II). Over 5 years of follow-up, remission rates for African Americans and Latinos with PTSD in this sample were 0.35 and 0.15 respectively, and reported frequency of experiences with discrimination significantly predicted PTSD diagnostic status in this sample, but did not predict any other anxiety or mood disorder. These findings demonstrate the chronic course of PTSD in African American and Latino adults, and highlight the important role that racial and ethnic discrimination may play in the development of PTSD among these populations. Implications for an increased focus on these sociocultural stressors in the assessment and treatment of PTSD in African American and Latino individuals are discussed.

Nightmares that replicate traumatic events are among the criteria that define posttraumatic stress disorder (PTSD); however, there has been limited systematic assessment of the content of dreams in PTSD. A PTSD dream rating instrument was developed to operationalize features attributed to dreams associated with combat-related PTSD that incorporated dimensions from the dream content analysis literature, and its reliability was assessed. Then the instrument was used to characterize dream reports in 18 Vietnam combat veterans diagnosed with PTSD. Approximately half of the group's target dreams contained features characteristic of combat, and all but 3 (17%) were moderately to highly threatening. Fifty-three percent were set at least partially in the present and 79% contained distorted elements. We therefore conclude that target dreams of combat veterans with PTSD vary with regard to replication of trauma and elements normally associated with dreaming, but typically are threatening.
