创伤后应激障碍（PTSD）在美国印第安人中比在其他美国人中更常见。作为一种复杂的诊断，PTSD的评估方法在流行病学研究中各不相同，特别是在创伤标准方面。在这里，我们研究了美国印第安人服务利用，精神病学流行病学，风险和保护因素项目（AI-SUPERPFP）的数据，以估计在两个不同文化的美国印第安人保留社区的PTSD的终生患病率，使用两个公式计算PTSD患病率。AI-SUPERPFP是1997年至2000年进行的一项跨部门概率抽样调查。西南（n = 1，446）和北方平原（n = 1，638）部落成员生活或附近的保留地，年龄在15-57岁的采访时，随机抽样部落卷。创伤后应激障碍的估计是基于单一的最严重的创伤和3个最严重的创伤。患病率估计值因确定方法而异：单一最严重创伤（终生：5.9%至14.8%）与3次最严重创伤（终生：8.9%至19.5%）。与单事件方法相比，使用3-最差事件方法的患病率增加了28.3%。创伤后应激障碍在这些部落社区很普遍。这些结果也有助于强调需要更好地了解PTSD患病率的影响，目前的重点是一个单一的最坏的事件。
Posttraumatic stress disorder (PTSD) has been found to be more common among American Indian populations than among other Americans. A complex diagnosis, the assessment methods for PTSD have varied across epidemiological studies, especially in terms of the trauma criteria. Here, we examined data from the American Indian Service Utilization, Psychiatric Epidemiology, Risk and Protective Factors Project (AI-SUPERPFP) to estimate the lifetime prevalence of PTSD in two culturally distinct American Indian reservation communities, using two formulas for calculating PTSD prevalence. The AI-SUPERPFP was a cross-sectional probability sample survey conducted between 1997 and 2000. Southwest (n = 1,446) and Northern Plains (n = 1,638) tribal members living on or near their reservations, aged 15-57 years at time of interview, were randomly sampled from tribal rolls. PTSD estimates were derived based on both the single worst and 3 worst traumas. Prevalence estimates varied by ascertainment method: single worst trauma (lifetime: 5.9% to 14.8%) versus 3 worst traumas (lifetime, 8.9% to 19.5%). Use of the 3-worst-event approach increased prevalence by 28.3% over the single-event method. PTSD was prevalent in these tribal communities. These results also serve to underscore the need to better understand the implications for PTSD prevalence with the current focus on a single worst event.
