Introduction: Persons with mild intellectual disability or borderline intellectual functioning (MID-BIF, IQ 50–85) are at high risk for the development of posttraumatic stress disorder (PTSD). A diagnostic instrument to establish a valid and reliable DSM-5 PTSD diagnosis in adults with MID-BIF was lacking. Aim of the current study was to determine the reliability and validity of the Adapted ADIS-C PTSD-adults for the assessment of PTSD according to DSM-IV-TR and DSM-5 in adults with MID-BIF

Method: 106 adults (18– 72 years old) with MID-BIF were interviewed using the Adapted ADIS-C PTSD-adults

Results: Agreement between raters appeared to be good (mean Cohen’s kappa for traumatic event scores 0.84, fulfillment of PTSD A-criterion 0.50, and PTSD symptom scores 0.90). Content validity was supported by a significant positive association with scores on the IES-IDs, a DSM-IV PTSD screening instrument (DSM-IV: r = .58; DSM-5: r = .43; ps <.001). Convergent validity appeared to be good considering positive correlations between rates of PTSD symptoms and scores on the ADESS, measuring symptoms of anxiety and stress, depression, and social avoidance (DSM-IV: r = .47; DSM-5: r = .49; ps <.001)

Conclusion: The Adapted ADIS-C PTSD-adults is suitable for assessing DSM-5 PTSD in adults with MID-BIF, an important step to gain access to trauma-focused interventions that have shown to be applicable and potentially effective for this high-risk target group.

简介：轻度智力残疾或边缘性智力障碍（MID-BIF，IQ 50-85）的人患创伤后应激障碍（PTSD）的风险很高。缺乏一种诊断工具来建立对MID-BIF成人的有效和可靠的DSM-5 PTSD诊断。本研究的目的是确定适应性ADIS-C PTSD成人根据DSM-IV-TR和DSM-5对MID-BIF成人进行PTSD评估的可靠性和有效性

方法：使用适应性ADIS-C PTSD成人对106名MID-BIF成人（18-72岁）进行了访谈

结果：评分者之间的一致性似乎很好（创伤事件的Cohen kappa平均得分为0.84，PTSD A标准达到0.50，PTSD症状得分为0.90）。内容的有效性是通过一个显著正相关与在IES-ID的分数支撑，一个DSM-IV PTSD筛选仪（DSM-IV：- [R = 0.58; DSM-5：[R = 0.43; p小号<.001）。考虑到PTSD症状发生率与ADESS评分之间呈正相关，测量焦虑和压力症状，抑郁和社交回避症状，收敛效度似乎很好（DSM-IV：r = 0.47； DSM-5：r = .49 ; p s <.001）

结论：适应的ADIS-C PTSD成人适用于评估MID-BIF成人的DSM-5 PTSD，这是获得针对创伤的干预措施的重要步骤，该干预措施已被证明对于这种高风险患者是适用的并且可能有效目标组。
