This study investigated differences in posttraumatic stress disorder (PTSD) symptoms and poor health risk behaviors of Hispanics compared to non-Hispanic Whites and Blacks. Our sample, recruited from urban community centers, included 180 adults reporting experienced trauma consistent with diagnostic DSM IV Criterion A1 and A2 of PTSD. Results from bivariate analyses indicated that on a PTSD symptom level, significant differences existed in feeling distant or cut off from people, as reported by majority of Hispanics. Differences in somatization among ethnoracial groups were not significant. Hispanics smoked less than Blacks but more than non-Hispanic Whites. Hispanics reported less drinking than other ethnoracial groups. The likelihood of PTSD was not significantly associated with Hispanic ethnicity. Ethnicity and race was not associated with PTSD. Multivariate analyses indicated that poor health risk behaviors did not moderate the relationship between Hispanic ethnicity and likelihood of PTSD. Implications, limitations, and recommendations for future research are discussed.
