The role of ethnic identity in the relationship of race-related stress to PTSD symptoms among young adults.

Although many studies have shown that stronger ethnic identity is associated with better adjustment, the role of ethnic identity in the context of race-related threat is unclear. The purpose of this study was to examine the effect of ethnic identity on the severity of posttraumatic stress disorder (PTSD) symptoms in the context of race-related stress, particularly to examine whether ethnic identity moderates the effect of racism on consequent PTSD symptoms. Subjects were 91 undergraduate students (11% Caucasian, 6.6% African American, 18.7% Hispanic, 47.3% Asian, 5.5% Middle Eastern, and 8.8% Other) who reported experiences of race-related stress. Race-related stress, ethnic identity, and PTSD symptoms were assessed through self-report measures. Results of a simultaneous multiple regression indicated that ethnic identity moderated PTSD symptoms in response to perceived racism, such that stronger ethnic identity was associated with more PTSD symptoms in the face of increasing levels of race-related stress. Additionally, race-related stress independently predicted PTSD symptoms. These results are consistent with previous findings that ethnic identity increases the experience of distress in the context of self-relevant threat.
