Research indicates that parents of autistic children may have a higher risk of posttraumatic stress disorder (PTSD) than parents of neurotypical children. This study was to determine the optimal factor structure of two trauma screening assessments: the PTSD Checklist for and the International Trauma Questionnaire, within this parent population.
Confirmatory factor analysis examined and compared one novel model and 14 previously identified and trauma symptom models among Australian parents of autistic children ( = 563).
Three PTSD models (anhedonia, hybrid, and intrusion/distress) provided a marginal fit, with the novel intrusion/distress model offering a superior fit. None of the five models tested achieved a good overall fit. For , a three-factor model best fit the latent structure of PTSD symptoms. For complex PTSD (CPTSD), a two-factor second-order model and a six-factor first-order model provided a superior fit over five alternative CPTSD models.
Results strongly support the internal reliability and construct validity of the PTSD and CPTSD models in Australian parents of autistic children, as measured by the International Trauma Questionnaire. The models outperformed the best models, highlighting their superiority for this population. While more complex models showed better fit than simpler ones, they still did not achieve a good overall fit. Notably, the results were largely consistent when assessing individuals meeting Criterion A for PTSD, specifically in relation to parenting-related traumatic experiences. The International Trauma Questionnaire is a more reliable and suitable tool for assessing PTSD and CPTSD in Australian parents of autistic children.

研究表明，自闭症儿童的父母患创伤后应激障碍（PTSD）的风险可能高于神经发育正常儿童的父母。本研究旨在确定两种创伤筛查评估工具——《PTSD检查表》和《国际创伤问卷》——在这一家长群体中的最佳因素结构。
验证性因素分析检验并比较了一种新的PTSD模型以及14种先前确定的PTSD和复杂创伤症状模型，研究对象为澳大利亚自闭症儿童的父母（n = 563）。
三种PTSD模型（快感缺乏型、混合型和侵入/痛苦型）拟合度一般，新的侵入/痛苦型模型拟合度更佳。所测试的五种复杂PTSD模型均未达到良好的整体拟合度。对于PTSD，三因素模型最能拟合PTSD症状的潜在结构。对于复杂PTSD（CPTSD），两因素二阶模型和六因素一阶模型比五种替代CPTSD模型的拟合度更佳。
结果有力地支持了通过《国际创伤问卷》测量的PTSD和CPTSD模型在澳大利亚自闭症儿童父母中的内部信度和结构效度。PTSD模型优于最佳的复杂PTSD模型，凸显了其在该群体中的优越性。虽然更复杂的复杂PTSD模型比简单模型拟合度更好，但仍未达到良好的整体拟合度。值得注意的是，在评估符合PTSD A标准的个体时，尤其是与育儿相关的创伤经历方面，结果基本一致。《国际创伤问卷》是评估澳大利亚自闭症儿童父母PTSD和CPTSD更可靠、更合适的工具。（PsycInfo数据库记录（c）2025美国心理学会，保留所有权利）
