War-Related PTSD in Black, Hispanic, and Majority White Vietnam Veterans
This chapter investigates elevated prevalence of chronic PTSD for black and Hispanic Vietnam veterans. Previous research relied on retrospective reports of war-zone stress and on PTSD assessments that failed to distinguish between prevalence and incidence. This chapter addresses these limitations using record-based exposure measures and clinical diagnoses on a subsample of NVVRS veterans. Compared with majority white, it explains the black elevation by blacks’ greater exposure to combat and the Hispanic elevation by Hispanics’ greater exposure, younger age, lesser education, and lower Armed Forces Qualification Test (AFQT) scores. Hispanics’ younger age mainly accounts for the PTSD elevation in Hispanics versus blacks. The main reason for the group differences in severity of exposure appears to be racial-ethnic contrasts in the military branches in which the veterans served.
