Abstract

The current study evaluated the psychometric properties of the Comprehensive Trauma Interview Post-Traumatic Stress Disorder (PTSD) Symptoms Scale (CTI-PSS), a novel method of assessing PTSD symptoms following exposure to a range of child adversities in the child maltreatment population. A sample of female adolescents ( n = 343) exposed to substantiated child sexual abuse and a nonmaltreated comparison condition completed the CTI-PSS and other established measures to assess internal consistency, factor structure, test discriminability as well as convergent, discriminant, and incremental validities. Results demonstrated that the CTI-PSS is a reliable and valid measure of PTSD symptoms with good discriminability and a factor structure that fits existing conceptualizations of the PTSD construct. It also demonstrated strong convergence with an established measure of PTSD symptoms and explained unique variance in the prediction of child sexual abuse status. Overall, the CTI-PSS appears to be a useful instrument for assessing PTSD symptoms in the child maltreatment population.

摘要

本研究评估了综合创伤访谈创伤后应激障碍(PTSD)症状量表(CTI-PSS)的心理测量特性,这是一种评估遭受儿童虐待人群在经历一系列儿童期逆境后PTSD症状的新方法。一个遭受确凿儿童性虐待的女性青少年样本(n = 343)以及一个未受虐待的对照样本完成了CTI-PSS和其他既定测量,以评估内部一致性、因子结构、测试辨别力以及聚合效度、区分效度和增量效度。结果表明,CTI-PSS是一种可靠且有效的PTSD症状测量工具,具有良好的辨别力和符合PTSD结构现有概念化的因子结构。它还与一种既定的PTSD症状测量方法有很强的聚合性,并在预测儿童性虐待状况方面解释了独特的方差。总体而言,CTI-PSS似乎是评估遭受儿童虐待人群中PTSD症状的一种有用工具。
