Elevated prevalence rates of chronic posttraumatic stress disorder (PTSD) have been reported for Black and Hispanic Vietnam veterans. There has been no comprehensive explanation of these group differences. Moreover, previous research has relied on retrospective reports of war-zone stress and on PTSD assessments that fail to distinguish between prevalence and incidence. These limitations are addressed by use of record-based exposure measures and clinical diagnoses of a subsample of veterans from the National Vietnam Veterans Readjustment Study (NVVRS). Compared with Majority White, the Black elevation is explained by Blacks' greater exposure; the Hispanic elevation, by Hispanics' greater exposure, younger age, lesser education, and lower Armed Forces Qualification Test scores. The PTSD elevation in Hispanics versus Blacks is accounted for mainly by Hispanics' younger age.
据报道,越战时期的黑人和西班牙裔退伍军人中,慢性创伤后应激障碍(PTSD)的患病率较高。目前尚无对这些群体差异的全面解释。此外,以往的研究依赖于对战区压力的回顾性报告以及未能区分患病率和发病率的PTSD评估。本研究通过使用基于记录的暴露测量方法和对来自越南退伍军人重新适应研究(NVVRS)的退伍军人子样本进行临床诊断,解决了这些局限性。与多数白人相比,黑人中PTSD患病率较高是因为黑人暴露程度更高;西班牙裔中PTSD患病率较高则是因为西班牙裔暴露程度更高、年龄更小、受教育程度较低以及武装部队资格测试分数较低。西班牙裔与黑人相比,PTSD患病率较高主要是因为西班牙裔年龄更小。
