Computerized Adaptive Version of the PEDI

描述（由申请人提供）：我们的目标是在评估儿童和青少年残疾的技术方面取得重大进展。在儿童年龄组和护理环境中识别残疾和评估个体进展的测量和实际要求，对当前的固定项目调查工具提出了严重的困境。我们开发了一种计算机化的自适应应用程序原型，称为PEDI- cat，与儿科残疾评估量表（PEDI）的全长版本相比，该应用程序产生了相当的评分水平、精度和对变化的响应性，显著减少了被调查者的负担。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项目池。将通过收集新PEDI的一般人群数据，开发PEDI功能量表（流动性、自我保健和社会功能）的基于规范的项目校准。评分算法和评分报告将创建一个完全可操作的PEDI-CAT系统。完整的PEDI-CAT将在评分水平上进行可靠性、有效性和准确性评估，以创建一个评估儿童和青少年残疾的操作系统，从而改进临床研究和实践中的测量方法。具体目标是：1。扩大原来的PEDI项目池，包括行动能力、自我照顾和社会功能，纳入适合14岁以下儿童的功能性任务；通过内容专家反馈、家长和临床医生焦点小组的认知测试和小型实地研究（N=100）来评估新项目。2. 通过收集两个具有全国代表性的6个月至14岁儿童看护人员的大型样本的回复，为修订后的功能项目库制定最终的项目校准和规范概况：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）与不同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（例如桌面，手持设备）上进行管理；通过真实数据模拟研究证明了PEDI-CAT的准确性、精密度和减少应答者负担。4. 在已知残疾状况不同的儿童临床样本中，确认PEDI-CAT的有效性和被调查者的接受程度：接受康复服务（N=50）与未接受康复服务（N=50）。一个实用和可行的PEDI-CAT将极大地改善在残疾状况、服务资格、项目需求、康复干预结果和临床研究决策中使用的信息。这项新的残疾评估将用一个更实用和精确的系统填补一个关键的空白，该系统可在桌面和手持设备上全面操作。

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.
