Validating a child acute stress measure in English and Spanish

描述（由申请人提供）：这项工作的广泛，长期的目标是建立一个实用和实用的声音手段，以评估儿童的急性应激反应后，潜在的创伤性事件（如事故，火灾，灾害），并扩大我们的理解急性创伤应激反应的儿童。短期，可访问的急性压力的措施，可以优化稀缺的心理健康资源的使用，确定创伤暴露的儿童与立即的痛苦，值得干预和指导努力，以防止长期后遗症。这项研究建立在NIH资助的项目上，该项目开发了儿童和青少年急性应激障碍（ASD）的第一个简短的自我报告措施（儿童急性应激清单，或ASC-Kids），以及随后的工作，利用仪器翻译/适应的最佳实践来创建西班牙语版本（Reacciones Agudas Postraumaticas - Menores，或RAP-M）。目前的研究的具体目标是评估的信度和效度的ASC-儿童和RAP-M在平行样本的英语和西班牙语的儿童（各200），检查和比较的措施的因素结构，并评估潜在的差异项目功能语言版本之间。为了实现这些目标，在过去一个月内暴露于潜在创伤事件的儿童（8至1 - 7岁）将在三个州（PA，CA，FL）的医疗机构中招募，进行初步评估和两次简短的随访（1-7天和3个月后）。该研究将评估测量的重测信度，临床ASD诊断的同时效度，收敛/判别效度（焦虑/抑郁症状）和预测效度（后期PTSD症状）。实证因素分析将评估三个模型的拟合，来自理论和实证文献，ASD症状的结构。英语和西班牙语版本之间的测量不变性将通过多样本CFA和项目功能差异的IRT分析进行检查。还将在双语子样本中研究措施之间的关联。该项目解决了在评估创伤和暴力对儿童心理健康的影响以及在评估讲西班牙语的儿童方面的一个关键差距。它将推进NIH在医疗保健环境中增加心理健康筛查的目标，特别是在儿童急性压力领域，因为医疗提供者是在交通事故，火灾或灾难等创伤事件后第一批看到儿童的人。

DESCRIPTION (provided by applicant): The broad, long-term objectives of this work are to establish a practical and empirically-sound means to assess children's acute stress reactions after potentially traumatic events (eg, accidents, fires, disasters) and to expand our understanding of acute traumatic stress responses in children. Brief, accessible measures of acute stress can optimize use of scarce mental health resources by identifying trauma-exposed children with immediate distress that warrants intervention and guiding efforts to prevent long-term sequelae. This study builds on an NIH-funded project that developed the first brief self-report measure for acute stress disorder (ASD) in children and adolescents (the Acute Stress Checklist for Children, or ASC-Kids), and subsequent work that utilized best practices in instrument translation / adaptation to create a Spanish version (the Reacciones Agudas Postraumaticas - Menores, or RAP-M). Specific aims of the current study are to assess the reliability and validity of the ASC-Kids and RAP-M in parallel samples of English- and Spanish-speaking children (200 each), to examine and compare the factor structures of the measures, and to assess potential differential item functioning between language versions. To achieve these aims, children (8 to 17) exposed to a potentially traumatic event within the past month will be recruited in healthcare settings in three states (PA, CA, FL) for an initial assessment and two brief follow-ups (1-7 days and 3 months later). The study will evaluate the measures' test-retest reliability, concurrent validity with clinician ASD diagnosis, convergent / discriminant validity (anxiety / depression symptoms), and predictive validity (later PTSD symptoms). Confirmatory factor analyses will assess the fit of three models, derived from theory and empirical literature, for the structure of ASD symptoms. Measurement invariance between English and Spanish versions will be examined via multi-sample CFA and by IRT analyses of differential item functioning. Associations between measures will also be examined in a bilingual sub-sample. This project addresses a key gap in assessment of child mental health consequences of trauma and violence and in assessment of Spanish-speaking children. It will advance the NIH objective of increasing mental health screening in health care settings, especially appropriate in the area of child acute stress because medical providers are among the first to see children after traumatic events such as traffic crashes, fires, or disasters.
