Abstract

Background: The most frequently used measure of the 11th edition of the International Classification of Diseases (ICD-11) complex posttraumatic stress disorder (CPTSD) is the International Trauma Questionnaire (ITQ). While there is strong support for the psychometric properties of the ITQ, few studies have assessed its reliability and validity in nationally representative samples. Additionally, several correlates of ICD-11 CPTSD have been identified; however, few studies have assessed multiple correlates simultaneously.

Objective: To assess the factorial validity and internal reliability of the ITQ in a nationally representative sample of adults living in Ireland (N = 1,100); determine the prevalence rates of ICD-11 posttraumatic stress disorder (PTSD) and CPTSD; and identify correlates of CPTSD symptoms and how CPTSD symptoms relate to risk of suicide.

Method: Confirmatory factor analysis was performed to evaluate the factorial validity of the ITQ, and structural equation modeling (SEM) was used to determine the unique multivariate associations between 10 predictor variables (age, sex, urban dwelling, unemployment status, number of traumatic events, COVID-19 infection, knowing someone who died from COVID-19, loneliness, social support, and sleep problems) and symptoms of CPTSD, and the unique associations between CPTSD symptoms and suicide risk.

Results: The ITQ produces reliable and valid scores, 11.2% of people met requirements for ICD-11 PTSD (2.4%) or CPTSD (8.8%), exposure to a higher number of traumatic life events, higher levels of loneliness, and more sleep problems predicted CPTSD symptoms; and negative self-concept (NSC) symptoms were most strongly associated with suicidality.

评估爱尔兰 ICD-11 创伤后应激障碍和复杂创伤后应激障碍的患病率、有效性和相关性。

背景：国际疾病分类（ICD-11）第 11 版复杂创伤后应激障碍（CPTSD）最常用的测量方法是国际创伤问卷（ITQ）。虽然 ITQ 的心理测量特性得到了强有力的支持，但很少有研究对其在全国代表性样本中的可靠性和有效性进行评估。此外，ICD-11 CPTSD 的几个相关因素已被确定；但是，很少有研究同时评估多个相关因素：目的：在具有全国代表性的爱尔兰成年人样本（N = 1,100）中评估 ITQ 的因子有效性和内部可靠性；确定 ICD-11 创伤后应激障碍 (PTSD) 和 CPTSD 的患病率；确定 CPTSD 症状的相关因素以及 CPTSD 症状与自杀风险的关系：方法：对ITQ进行确证因子分析以评估其因子有效性，并使用结构方程建模（SEM）确定10个预测变量（年龄、性别、城市居民、失业状况、创伤事件次数、COVID-19感染、认识死于COVID-19的人、孤独、社会支持和睡眠问题）与CPTSD症状之间的独特多变量关联，以及CPTSD症状与自杀风险之间的独特关联：ITQ可得出可靠有效的分数，11.2%的人符合ICD-11创伤后应激障碍（2.4%）或创伤后应激障碍（8.8%）的要求，更多的创伤性生活事件、更高程度的孤独感和更多的睡眠问题可预测创伤后应激障碍症状；负性自我概念（NSC）症状与自杀倾向的关系最为密切：结论：在自杀风险较高的情况下，治疗消极自我概念症状、孤独感和睡眠问题可能是明智之举。(PsycInfo Database Record (c) 2024 APA, 版权所有）。
