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.

撮要:創傷後壓力症(PTSD)在美國人中較常見於印弟安裔人。但流行病學研究上由於PTSD為一複雜診斷，而且評核方法亦隨不同研究而異，尤其是關於創傷的定義。所以我們選取了美國印弟安醫療服務使用者的精神病流行學，風險及保護因素研究計劃(AI-SUSERPFP)來估計在兩個文化不同的美國印弟安保育社區中PTSD的終身發病率，其中使用兩個不同的程式去計算。AI-SUSERPFP 為在1997–2000年進行的一個橫斷面概率樣本調查。從部落名册中隨機抽樣了15–57歲居住在西南(N = 1,446)和北部(N = 1,638)平原的部族人士。從單一最重和三個嚴重創傷中得出PTSD估值。發病率估值依不同確認方法而異：單一最重創傷(終身：5.9%至14.8%)比對三個嚴重創傷(終身：8.9%至19.5%)。使用三個嚴重創傷事件方法比單一事件增多28.3%發病率。在這些部落社區中，PTSD是普遍的。本研究結果對現行聚焦單一嚴重事件的PTSD發病率有更深層次的理解。
