Gender differences in exposure to potentially traumatic events and diagnosis of posttraumatic stress disorder (PTSD) by racial and ethnic group.

Objective: There is a robust literature base documenting gender differences and racial/ethnic differences in exposure to potentially traumatic events (PTEs) and posttraumatic stress disorder (PTSD) diagnosis. Yet, to the best of our knowledge, this is the first study to evaluate the risk of PTEs and PTSD between genders, stratified by race/ethnicity. We aimed to better understand whether factors associated with poor psychological adjustment following PTEs (e.g., PTE type, sociodemographic factors, social support) varied by gender and race/ethnicity.

Method: Data were collected from three U.S.-based national studies comprising the Collaborative Psychiatric Epidemiologic Surveys (CPES; N = 13,649). Trained lay interviewers administered questionnaires and collected data on PTE exposure, PTSD, and psychosocial covariates. Regression analyses were conducted to investigate relations between PTEs, PTSD, and gender, stratified by race/ethnicity.

Results: Adjusting for sociodemographic variables, mental health comorbidity, social support, and PTE frequency, White, African-American, and Afro-Caribbean women had higher odds of PTSD than men in their respective racial/ethnic groups, whereas gender differences were not observed for Latinos or Asians.

Conclusion: Findings suggest that risk of exposure to PTEs and PTSD may differ by gender and race/ethnicity. Future studies should consider the contributions of social, cultural, and contextual factors in estimating PTSD risk.
