本研究旨在描述PROMIS儿科积极情感试题库、儿童报告版和家长代理版的心理测量学评价和项目反应理论（IRT）校准。最初的项目池包括53个项目，以前开发的定性方法，管理1874名8-17岁的儿童和909名5-17岁儿童的父母。分析包括描述性统计，信度，因素分析，差异项目功能，和结构效度。共删除了14个项目，因为心理测量性能差，和一个8项的简短的形式，从其余的39个项目构建的1004名8-17岁的儿童和1306名5-17岁的儿童的父母的全国样本进行管理。将合并的样品用于IRT校准分析。最终的项目银行出现一维，项目出现局部独立，项目是免费的差异项目功能。量表具有良好的信度和收敛效度和判别效度。积极影响随着儿童年龄的增长而下降，对于那些有特殊医疗保健需求的儿童来说，积极影响更低。经IRT校正后，我们发现4和8项目简表在大范围的潜在特质（> 4 SD单位）上具有较高的精确度（可靠性）。PROMIS儿科积极情感试题库及其简短表格提供了一个有效的，准确的，有效的评估儿童和青少年的积极情感。
The purpose of this study is to describe the psychometric evaluation and item response theory (IRT) calibration of the PROMIS Pediatric Positive Affect item bank, child-report and parent-proxy editions. The initial item pool comprising 53 items, previously developed using qualitative methods, was administered to 1874 children 8-17 years old and 909 parents of children 5-17 years old. Analyses included descriptive statistics, reliability, factor analysis, differential item functioning, and construct validity. A total of 14 items were deleted, because of poor psychometric performance, and an 8-item short form constructed from the remaining 39 items was administered to a national sample of 1004 children 8-17 years old, and 1306 parents of children 5-17 years old. The combined sample was used in IRT calibration analyses. The final item bank appeared unidimensional, the items appeared locally independent, and the items were free from differential item functioning. The scales showed excellent reliability and convergent and discriminant validity. Positive affect decreased with children's age and was lower for those with a special health care need. After IRT calibration, we found that 4 and 8 item short forms had a high degree of precision (reliability) across a wide range of the latent trait (> 4 SD units). The PROMIS Pediatric Positive Affect item bank and its short forms provide an efficient, precise, and valid assessment of positive affect in children and youth.
