OBJECTIVE Psychological trauma is an important public health problem, but previous measurement tools have primarily focused on childhood traumatic events while trauma exposure in adulthood (>18 years of age) has received less attention. The purpose of this study was to examine the psychometric properties of an instrument for assessment of psychological trauma in adulthood, the Adulthood Trauma Inventory (ATI). METHOD Participants (n = 893) completed the ATI, a 33-item questionnaire modeled after the Early Trauma Inventory-Self Report (ETI-SR), assessing traumatic events occurring after 18 years of age. Participants also completed instruments to assess depression, posttraumatic stress disorder (PTSD), and early trauma (ETI-SR). Internal consistency and item response theory metrics were examined. RESULTS ATI total score (number of items endorsed) yielded the greatest internal consistency (Cronbach's α = .77) and was significantly (p < .0001) correlated with indices of PTSD (ρ = 0.40), depression (ρ = 0.31), and early trauma (ρ = 0.56). Area under the curve and accuracy values ranged from 0.65 and 70% (depression) to 0.75 and 95% (current PTSD). CONCLUSIONS The ATI is a valid measure of adult psychological trauma that may be useful for both clinical assessment and research involving the long-term effects on the individual and psychobiology.

成年创伤量表的心理计量学特性。

目的心理创伤是一个重要的公共卫生问题，但是以前的测量工具主要关注儿童创伤事件，而成年（> 18岁）的创伤暴露却受到较少的关注。这项研究的目的是要检查一种评估成年期心理创伤的工具-成年创伤量表（ATI）的心理测量特性。方法参与者（n = 893）完成了一项ATI（33项调查表），该调查表是根据“早期创伤自我评估报告”（ETI-SR）建模的，评估了18岁后发生的创伤事件。参与者还完成了评估抑郁症，创伤后应激障碍（PTSD）和早期创伤（ETI-SR）的工具。内部一致性和项目反应理论指标进行了审查。结果ATI总得分（认可的项目数）产生了最大的内部一致性（Cronbach'sα= .77），并且与PTSD指数（ρ= 0.40），抑郁症（ρ= 0.31）和显着相关（p <.0001）。早期创伤（ρ= 0.56）。曲线下的面积和精度值的范围从0.65和70％（降低）到0.75和95％（当前PTSD）。结论ATI是成人心理创伤的一种有效措施，可能对临床评估和涉及对个体和心理生物学的长期影响的研究均有用。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。曲线下的面积和精度值的范围从0.65和70％（降低）到0.75和95％（当前PTSD）。结论ATI是成人心理创伤的一种有效措施，可能对临床评估和涉及对个体和心理生物学的长期影响的研究均有用。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。曲线下的面积和精度值的范围从0.65和70％（降低）到0.75和95％（当前PTSD）。结论ATI是成人心理创伤的一种有效措施，可能对临床评估和涉及对个体和心理生物学的长期影响的研究均有用。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
