Computerized Adaptive Version of the PEDI

描述（由申请人提供）：我们的目标是实现用于评估儿童和青少年残疾的技术的重大进步。确定残疾和评估儿科年龄组和护理环境的个人进步的测量和实际要求目前的固定项目调查工具提出了一个严重的困境。我们已经开发了一个原型计算机化的，自适应的应用程序，称为PEDI-CAT，产生可比的评分水平，精度，并在显着减少应答者负担的变化的反应相比，全长版本的儿科残疾评估量表（PEDI）规模。第二阶段的工作将通过扩大每个量表测量的适当年龄范围来改善PEDI项目库。将通过收集新PEDI的一般人群数据，开发PEDI功能量表（活动性、自我护理和社会功能）的基于标准的项目校准。评分算法和评分报告将被创建为一个完全可操作的PEDI-CAT系统。完整的PEDI-CAT将在各个评分水平的可靠性，有效性和精确性方面进行评估，以创建一个评估儿童和青少年残疾的操作系统，这将改善临床研究和实践中的测量。具体目标是：1。扩展移动性，自我护理和社会功能的原始PEDI项目库，以纳入适合14岁以下儿童的功能任务;通过内容专家反馈，父母和临床医生焦点小组的认知测试以及小型实地研究（N=100）评估新项目。2.通过收集两个具有全国代表性的大型6个月至14岁儿童看护者样本的响应，为修订后的功能项目库开发最终项目校准和规范性特征：1）基于电话的调查样本（N=840）; 2）基于网络的调查样本（N=1400）。估计数据收集方法（互联网与电话）与差异项目功能相关的程度。3.创建一个完全可操作的PEDI-CAT系统，该系统具有基于规范的评分和解释性报告，可以在多个平台上进行管理（例如，台式、手持设备）;通过真实的数据模拟研究证明PEDI-CAT的准确性、精确度和应答负担的减少。4.确认PEDI-CAT在已知残疾状况不同的儿童临床样本中的有效性和应答者接受程度：接受康复服务（N=50）与不接受康复服务（N=50）。一个实际可行的PEDI-CAT将大大改善用于决策的残疾状况，服务资格，计划需求，康复干预的结果和临床研究的信息。这一新的残疾评估将填补一个重要的空白，其系统更加实用和精确，可在台式和手持设备上全面运行。

DESCRIPTION (provided by applicant): Our objective is to achieve a major advance in the technology used to assess disability in children and youth. Measurement and practical requirements for identifying disability and evaluating individual progress across pediatric age groups and care settings present a serious dilemma to current fixed-item survey instruments. We have developed a prototype computerized, adaptive application called PEDI-CAT that produces comparable scoring levels, precision, and responsiveness to change at significant reductions in respondent burden compared to full-length version of Pediatric Evaluation of Disability Inventory (PEDI) scales. Phase II work will improve the PEDI item pool by broadening the appropriate age range measured by each scale. Norm-based item calibrations for the PEDI functional scales (mobility, self-care, and social functioning) will be developed by collecting general population data for the new PEDI. Scoring algorithms and score reports will be created for a fully operational PEDI-CAT system. The full PEDI-CAT will be evaluated in terms of reliability, validity, and precision across score levels to create an operational system for the assessment of disability in children and youth that will improve measurement in clinical research and practice. Specific aims are to: 1. Expand the original PEDI item pool in mobility, self-care and social functioning to incorporate functional tasks appropriate for children to 14 years of age; evaluate new items through content expert feedback, cognitive testing in parent and clinician focus groups, and a small field study (N=100). 2. Develop final item calibrations and normative profiles for the revised functioning item pools by collecting responses from two large, nationally-representative samples of caretakers for children age 6 months to 14 years: 1) a telephone-based survey sample (N=840); and 2) a web-based survey sample (N=1400). Estimate the extent to which data collection method (internet vs. telephone) is associated with differential item functioning. 3. Create a fully operational PEDI-CAT system with norm-based scoring and interpretive reports that can be administered on multiple platforms (e.g., desktop, hand-held devices); demonstrate the accuracy, precision, and reductions in respondent burden of the PEDI-CAT through real data simulation studies. 4. Confirm the validity and respondent acceptance of the PEDI-CAT in a clinical sample of children known to differ in disability status: receiving rehabilitation services (N=50) vs. not (N=50). A practical and feasible PEDI-CAT will greatly improve the information used in making decisions about disability status, service eligibility, program needs, outcomes of rehabilitation interventions and in clinical research. This new disability assessment will fill a critical void with a system that is more practical and precise, programmed to be fully operational on both desktop and hand-held devices.
