- Abstract: Traumatic event checklists typically ask respondents to indicate whether they have experienced particular types of potentially traumatic events (PTEs) and then sum these endorsements to gauge cumulative trauma exposure. However, the sum of these endorsements indicates the variety of PTEs respondents have experienced rather than the count of exposure events. The main objective of the present study was to explore the association between PTE count and variety to examine assumptions regarding the use of traumatic event checklists to measure cumulative trauma exposure. The limited empirical research suggests that count and variety are strongly associated; however, there may be variation in magnitude concerning whether participants' environments confer an increased or decreased risk of exposure. We present Life Event Checklist data from a large sample of Mexican and U.S. participants ( n = 1, 820), which allowed us to compare reports of count and variety. Count and variety were strongly correlated, Kendall's tau‐b = .74, such that count accounted for 54.6% of the variance in variety. A negative binomial regression analysis revealed that this association was moderated by county and municipio homicide rate, used as a proxy for violent crime, but not by natural disaster history. Variety was more strongly associated with scores on the Posttraumatic Stress Checklist for DSM‐5, Kendall's tau‐b = .26, than was PTE count, Kendall's tau‐b = .22, Fisher's z = −8.04, p < .001.Abstract: Traumatic event checklists typically ask respondents to indicate whether they have experienced particular types of potentially traumatic events (PTEs) and then sum these endorsements to gauge cumulative trauma exposure.

Resumen: Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Midiendo exposición a trauma: recuentos de eventos potencialmente traumáticos versus variedad en una muestra binacional RECUENTO VERSUS VARIEDAD DE EVENTOS POTENCIALMENTE TRAUMÁTICOS Los checklist de eventos traumáticos suelen pedir a los encuestados que indiquen si han experimentado tipos particulares de eventos potencialmente traumáticos (EPT) y luego suman estas confirmaciones para medir la exposición acumulativa de trauma. Sin embargo, la suma de estas confirmaciones indica la variedad de EPT que los encuestados han experimentado, en lugar del recuento de eventos de exposición. El objetivo principal del presente estudio fue explorar la asociación entre el recuento y variedad de EPT para examinar suposiciones sobre el uso de checklists de eventos traumáticos para medir exposición acumulativa al trauma. La limitada investigación empírica sugiere que el recuento y la variedad están fuertemente asociados; sin embargo, puede haber variación en la magnitud con respecto a si los entornos de los participantes confieren un mayor o menor riesgo de exposición. Presentamos datos de Life Event Checklist en una gran muestra de participantes mexicanos y estadounidenses ( n = 1, 820), que nos permitió comparar informes de recuento y variedad. El recuento y la variedad estaban fuertemente correlacionados, Tau‐b de Kendall = .74, de modo que el recuento representó el 54.6% de la varianza en la variedad. Un análisis de regresión binomial negativo reveló que esta asociación fue moderada por el condado y la tasa de homicidios del municipio, utilizada como proxy de los delitos violentos, pero no por el historial de desastres naturales. La variedad se asoció más fuertemente con las puntuaciones en la lista de verificación de estrés postraumático para el DSM‐ 5, tau‐b de Kendall = .26, que lo que fue el recuento de EPT, tau‐b de Kendall = .22, z de Fisher = ‐8.04, p <.001. Aunque existen desafíos para estimar los recuentos de EPT, los presentes hallazgos sugieren que la variedad de EPT no es un buen indicador de la exposición acumulada al trauma. 抽象: 簡體及繁體中文撮要由亞洲創傷心理研究學會翻譯 JOTS‐19‐0435.R2 Rasmussen Measuring Trauma Exposure: Count Versus Variety of Potentially Traumatic Events in a Binational Sample Traditional Chinese 標題: 測量創傷經歷:比對兩個國家樣本中潛在創傷事件的發生次數和事件種類 撮要: 創傷事件的檢查表通常會問受訪者, 有否經歷過指定種類的潛在創傷事件(PTEs), 再將這些項目相加, 以計算出累積創傷經歷。但是, 這種累積計算反映的是受訪者經歷的PTEs事件種類, 而非其經歷的事件次數。本研究的主要目的, 是檢視PTEs數量跟種類的關係, 以探討使用創傷事件檢查表來測量累積創傷經歷所涉及的假設。目前, 有限的實證研究指, 經歷次數和事件種類之間有強勁關連;但視乎樣本的環境有沒有提升或減低其受創的風險, 此關連的強度可能會有所不同。我們檢視由墨西哥和美國參加者 ( n = 1, 820) 組成的大型樣本, 以他們的人生事件檢查表數據, 比較經歷次數和事件種類。經歷次數和事件種類的關連強勁, Kendall's tau‐b = .74, 經歷次數解釋了事件種類54.6%的方差。二項迴歸分析反映, 這個關連受郡及市的謀殺率 (作為暴力罪行的替代) 所調節, 而不受以往的天災經歷調節。事件種類跟 DSM‐5 創傷後壓力檢查表的分數關連, Kendall's tau‐b = .26, 比跟PTE次數的關連更強, Kendall's tau‐b = .22, Fisher's z = ‐8.04, p < .001。雖然在推算PTE次數方面存在困難, 但本研究結果反映, PTE事件種類並非累積創傷經歷的可靠替代。 Simplified Chinese 标题: 测量创伤经历:比对两个国家样本中潜在创伤事件的发生次数和事件种类 撮要: 创伤事件的检查表通常会问受访者, 有否经历过指定种类的潜在创伤事件(PTEs), 再将这些项目相加, 以计算出累积创伤经历。但是, 这种累积计算反映的是受访者经历的PTEs事件种类, 而非其经历的事件次数。本研究的主要目的, 是检视PTEs数量跟种类的关系, 以探讨使用创伤事件检查表来测量累积创伤经历所涉及的假设。目前, 有限的实证研究指, 经历次数和事件种类之间有强劲关连;但视乎样本的环境有没有提升或减低其受创的风险, 此关连的强度可能会有所不同。我们检视由墨西哥和美国参加者 ( n = 1, 820) 组成的大型样本, 以他们的人生事件检查表数据, 比较经历次数和事件种类。经历次数和事件种类的关连强劲, Kendall's tau‐b = .74, 经历次数解释了事件种类54.6%的方差。二项回归分析反映, 这个关连受郡及市的谋杀率 (作为暴力罪行的替代) 所调节, 而不受以往的天灾经历调节。事件种类跟 DSM‐5 创伤后压力检查表的分数关连, Kendall's tau‐b = .26, 比跟PTE次数的关连更强, Kendall's tau‐b = .22, Fisher's z = ‐8.04, p < .001。虽然在推算PTE次数方面存在困难, 但本研究结果反映, PTE事件种类并非累积创伤经历的可靠替代。 … (more)
