Abstract

Background: The International Trauma Questionnaire (ITQ) is used to measure posttraumatic stress disorder (PTSD) and complex posttraumatic stress disorder (CPTSD) symptoms, and the Posttraumatic Cognitions Inventory-9 (PTCI-9) is used to measure posttraumatic cognitions. Both tools have been translated for use in Brazil. However, the psychometric properties of the Brazilian versions were not investigated, and no study has verified the invariance of these tools for many traumatic event types.

Objective: This study examined the validity, reliability, and measurement invariance of the Brazilian versions of the ITQ and the PTCI-9 for trauma type, gender, race, age group, education level, and geographical region.

Methods: A total of 2,111 people (67.74% women) participated in an online survey. The scale models were tested via confirmatory factor analyses and measurement invariance through multigroup analyses. Pearson's correlation analyses were used to examine the relationships between PTSD, CPTSD, posttraumatic cognitions, and depressive symptoms.

Results: Except for the affective dysregulation factor, the reliabilities of the ITQ and PTCI-9 dimensions were adequate. Models with six correlated dimensions for the ITQ and three correlated dimensions for the PTCI-9 showed adequate fit to the data. The ITQ and PTCI-9 exhibited scalar invariance for gender, race, age group, education level, and geographical region. The ITQ also demonstrated full invariance for trauma type. The factors of both instruments were related to each other and to depressive symptoms, with higher effect sizes for posttraumatic cognitions and complex posttraumatic stress disorder symptoms.

Conclusion: We recommend using the Brazilian versions of the ITQ and PTCI-9, which are crucial tools for assessing and treating trauma-related disorders.

国际创伤问卷》和《创伤后认知清单-9》:巴西版本的有效性证据和测量不变性。
背景:国际创伤问卷(ITQ)用于测量创伤后应激障碍(PTSD)和复杂创伤后应激障碍(CPTSD)症状,创伤后认知清单-9(PTCI-9)用于测量创伤后认知。这两种工具都已翻译成巴西语使用。然而,巴西版本的心理测量特性尚未得到调查,也没有研究证实这些工具对多种创伤事件类型具有不变性:本研究考察了巴西版 ITQ 和 PTCI-9 在创伤类型、性别、种族、年龄组、教育水平和地理区域方面的有效性、可靠性和测量不变性:共有 2111 人(67.74% 为女性)参与了在线调查。量表模型通过确认性因子分析进行检验,测量不变量通过多组分析进行检验。皮尔逊相关分析用于研究创伤后应激障碍、创伤后创伤性应激障碍、创伤后认知和抑郁症状之间的关系:结果:除情感调节障碍因素外,ITQ 和 PTCI-9 各维度的可靠度都很高。ITQ的六个相关维度和PTCI-9的三个相关维度的模型显示出与数据的充分拟合。ITQ 和 PTCI-9 在性别、种族、年龄组、教育水平和地理区域方面都表现出标度不变性。ITQ 在创伤类型方面也表现出完全不变性。两种工具的因子相互关联,并与抑郁症状相关,创伤后认知和复杂创伤后应激障碍症状的效应大小更高:我们建议使用巴西版的 ITQ 和 PTCI-9,它们是评估和治疗创伤相关障碍的重要工具。
