The aim of this study was to validate CAPS-5 for the Brazilian-Portuguese language on a sample of 128 individuals from two centers (from the cities of São Paulo and Porto Alegre) who have been recently exposed to a traumatic event. We performed a reliability analysis between interviewers (with a subset of 32 individuals), an internal consistency analysis, and a confirmatory factorial analysis for the validation study. The inter-rater reliability of the total PTSD symptom severity score was high [intraclass correlation coefficient =0.994, 95% CI (0.987-0.997), < 0.001]. Cohen's Kappa for individual items ranged between 0.759 and 1. Cronbach's alpha coefficients indicated high internal consistency for the CAPS-5 full scale (α = 0.826) and an acceptable level of internal consistency for the four symptom clusters. The confirmatory factorial analysis for the 20-item original CAPS-5 did not fit the data well. A 15-item model with better results was then established by excluding the following CAPS-5 items: dissociative amnesia, recklessness, distorted cognitions, irritability, and hypervigilance. Despite the limitation of the predominance of female victims, and the high number of sexually assaulted women in our sample, the model with only 15 items provided a good fit to the data with high internal consistency (α = 0.835).
本研究的目的是在来自两个中心（圣保罗市和阿雷格里港市）的128名近期遭受创伤性事件的个体样本中，对巴西葡萄牙语版的儿童创伤后应激障碍评定量表第五版（CAPS-5）进行验证。我们对访谈者之间进行了信度分析（对32名个体的子集）、内部一致性分析以及用于验证研究的验证性因素分析。创伤后应激障碍（PTSD）症状严重程度总分的评分者间信度很高[组内相关系数=0.994，95%置信区间（0.987 - 0.997），P<0.001]。各项目的科恩kappa系数在0.759至1之间。克朗巴哈系数表明CAPS-5全量表具有较高的内部一致性（α = 0.826），四个症状群的内部一致性水平可接受。对20项原始CAPS-5进行的验证性因素分析与数据拟合不佳。随后通过排除以下CAPS-5项目建立了一个结果更好的15项模型：分离性遗忘、鲁莽、认知扭曲、易怒和过度警觉。尽管存在女性受害者占主导以及样本中遭受性侵犯的女性数量较多的局限性，但仅15项的模型与数据拟合良好，内部一致性较高（α = 0.835）。
