DESCRIPTION (provided by applicant): This project seeks to expand traumatic stress clinical and research methods by developing and validating an innovative approach to measurement of trauma responses. Ecological Proximal Assessment (EPA) involves collecting self-reports that are frequent and proximal in time to the phenomena of interest by having participants make their reports on hand-held computers (PDAs) in their natural environments. EPA overcomes many limitations of standard measures, and the nature of the data allows use of multilevel data analysis methods to study directionality of relationships and within-person relationships. This project's primary aims are to investigate the feasibility, validity, and utility of EPA for measuring early responses to traumatic events. We will study aspects of recruitment, psychometric validity, and measurement reactivity of EPA in 140 hospital trauma patients or trauma-exposed family members. Using hierarchical linear modeling methods, we will also investigate hypotheses relating to the clinical utility of EPA and the dynamics of posttraumatic moods, cognitions, symptoms, and experiences. Demonstration that EPA is feasible and valid will enable use of the method for clinical assessments and research on between and within-person variables important in the development of posttraumatic psychological disorders. Ultimately, EPA methods may help clinicians identify recent trauma survivors who are at risk for the development of posttraumatic disorders and may allow tailoring of interventions to individual needs.

描述(由申请人提供)：该项目寻求通过开发和验证一种测量创伤反应的创新方法来扩展创伤应激临床和研究方法。生态邻近评估(EPA)包括通过让参与者在其自然环境中对手持计算机(PDA)进行报告来收集频繁且在时间上接近感兴趣的现象的自我报告。环保局克服了标准测量的许多局限性，数据的性质允许使用多层次数据分析方法来研究关系和人与人之间关系的方向性。该项目的主要目的是调查EPA用于测量创伤事件的早期反应的可行性、有效性和实用性。我们将对140名医院创伤患者或创伤暴露家庭成员进行EPA的招募、心理测量效度和测量反应性方面的研究。使用分层线性建模方法，我们还将调查与EPA的临床效用以及创伤后情绪、认知、症状和经验的动力学有关的假设。证明EPA是可行和有效的，将使该方法能够用于临床评估和研究在创伤后心理障碍发展中重要的人与人之间的变量。最终，环保局的方法可能会帮助临床医生识别最近的创伤幸存者，他们有患创伤后障碍的风险，并可能允许根据个人需求定制干预措施。
