目的评价父母自评认知功能量表（pedsPCF）的信度、效度和临床应用价值。方法来自美国。S.一般人群中，1，409名7-17岁儿童的父母完成了45个pedsPCF项目。采用项目反应理论（IRT）的方法，他们的心理测量特性进行了评估。采用受试者工作特征（ROC）曲线和判别函数分析预测儿童行为检查表（CBCL）量表的临床问题。计算机自适应测试（CAT）模拟用于评估临床效用。结果最终建立的43项pedsPCF试题库无项目偏倚，具有可接受的IRT参数，对相关临床问题有较好的预测作用。CAT模拟结果显示CAT与全长pedsPCF之间的相关性为0.98。结论pedsPCF具有良好的心理测量学特性，U. S.一般人群的规范，和一个简单而精确的CAT版本是可用的。未来的工作将评估pedsPCF在其他临床人群中的认知功能是重要的。
Objective The purpose of this study is to report the reliability, validity, and clinical utility of a parent-report perceived cognitive function (pedsPCF) item bank. Methods From the U. S. general population, 1,409 parents of children aged 7-17 years completed 45 pedsPCF items. Their psychometric properties were evaluated using Item Response Theory (IRT) approaches. Receiver operating characteristic (ROC) curves and discriminant function analysis were used to predict clinical problems on child behavior checklist (CBCL) scales. A computerized adaptive testing (CAT) simulation was used to evaluate clinical utility. Results The final 43-item pedsPCF item bank demonstrates no item bias, has acceptable IRT parameters, and provides good prediction of related clinical problems. CAT simulation resulted in correlations of 0.98 between CAT and the full-length pedsPCF. Conclusions The pedsPCF has sound psychometric properties, U. S. general population norms, and a brief-yet-precise CAT version is available. Future work will evaluate pedsPCF in other clinical populations in which cognitive function is important.
