Computerized Adaptive Version of the PEDI

描述(由申请人提供)：我们的目标是在用于评估儿童和青年残疾的技术方面取得重大进展。在儿科各年龄组和护理环境中确定残疾和评估个人进展的衡量和实际要求给目前的固定项目调查工具带来了严重的两难境地。为了解决这些不足，第一阶段的主要目标是：(1)基于现有的儿科残疾评价表(PEDI)规范和临床数据库建立一个原型计算机自适应测试(CAT)系统；(2)与使用现有数据库的全长PEDI(固定的)评分相比较，评估基于原型的PEDI-CAT评分的准确性和响应性；以及(3)评估在四个月的试点现场测试中对答复者负担的减少和对平行版本的PEDI-CAT和PEDI-FIXED的接受程度 儿科临床环境。第一阶段的产品将是儿科猫的原型版本，以及关于它工作得有多好的初步证据。在第二阶段，我们将检查原始儿科数据中心的问卷项目校准，增加新的项目以扩大年龄范围，进行实地研究以重新校准项目，并为全面运作的儿科计算机辅助测试系统创建算法。一个实用可行的儿科计算机辅助教学系统将极大地提高信息化水平。 用于决定残疾状况、服务资格、计划需求和康复干预的结果。这个SBIR项目的产品将是一个适销对路的CAT系统，用于评估6个月至18岁的儿童和青年的残疾情况。这一新的残疾评估由儿童残疾评估项目改编，并扩展到更广泛的年龄段，将用一个更实用和更准确的系统来填补一个关键的空白。会的 其优势是大大降低了数据收集成本，减轻了受访者的负担，并将在整个量表范围内满足单个患者级别的临床决策所需的评分精度标准。许多康复机构可能还会发现，该系统有助于满足标准化结果的认证和机构要求 以儿童为一组进行监测。

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 to identify disability and to evaluate individual progress across pediatric age groups and care settings present a serious dilemma to current fixed-item survey instruments. To address these deficiencies, the principal aims of Phase I are to: (1) build a prototype computer adaptive testing (CAT) system based on existing Pediatric Evaluation of Disability Inventory (PEDI) normative and clinical databases; (2) estimate the accuracy and responsiveness of scores based on the prototype PEDI-CAT in comparison with scores for the full-length PEDI (PEDI-Fixed) using existing databases; and (3) evaluate reductions in respondent burden and acceptance of parallel versions of the PEDI-CAT and PEDI-Fixed in a pilot field test in four pediatric clinical settings. The product in Phase I will be a prototype version of a PEDI-CAT as well as preliminary evidence regarding how well it works. In Phase II, we will examine the questionnaire item calibrations of the original PEDI, add new items to broaden the age range coverage, conduct field studies to re-calibrate items, and create algorithms for a fully operational PEDI-CAT system. A practical and feasible PEDI-CAT will greatly improve the information used in making decisions about disability status, service eligibility, program needs and outcomes of rehabilitation interventions. The product of this SBIR project will be a marketable CAT system for the assessment of disability in children and youth between the ages of 6 months and 18 years. Adapted from the PEDI, and expanded to a broader age group, this new disability assessment will fill a critical void with a system that is more practical and precise. It will have the advantage of greatly reduced data collection costs, reduced respondent burden and will meet the standards of score precision required for clinical decisions at the individual patient level throughout the scale range. Many rehabilitation settings may also find this system helpful in meeting accreditation and institutional requirements for standardizing outcome monitoring in groups of children.
