The primary objective was to enhance the content coverage of some of the pediatric self-report item banks for ages 8-17 years from the National Institutes of Health (NIH) Patient Reported Outcomes Measurement Information System (PROMIS®), and extend the range of precise measurement to higher levels of physical functioning.
Data from 1,419 pediatric patients with cancer, chronic kidney disease, obesity, rehabilitation needs, rheumatic disease, and sickle cell disease were combined with item responses from the original standardization sample of 3,048 children to calibrate new items for the pediatric PROMIS Anger, Anxiety, Depressive Symptoms, Pain Interference, Fatigue, and physical functioning Upper Extremity and Mobility scales. Simultaneous or concurrent calibration using the graded item response theory model placed all of the items on the same scale.
Twenty-two of 28 potential new items were added across the seven scales. A recommended short form was proposed for the Anger scale, and the recommended short forms for the Anxiety and Depressive Symptoms scales were revised. Unfortunately, we were not particularly successful at extending the range of measurement for the physical functioning banks.
The present study expanded PROMIS pediatric item banks to add new content and to increase the range of measurement. Using item response theory, the banks were revised and expanded without changing the underlying scale of measurement. For Anger, Anxiety, and Depressive Symptoms, we successfully added new content that may render those banks more robust and flexible.
主要目标是提高美国国立卫生研究院（NIH）患者报告结局测量信息系统（PROMIS®）中一些针对8至17岁儿童的自我报告项目库的内容覆盖范围，并将精确测量范围扩展到更高水平的身体功能。
将来自1419名患有癌症、慢性肾病、肥胖症、有康复需求、风湿性疾病和镰状细胞病的儿科患者的数据与来自3048名儿童的原始标准化样本的项目反应相结合，以校准儿科PROMIS愤怒、焦虑、抑郁症状、疼痛干扰、疲劳以及身体功能上肢和活动量表的新项目。使用分级项目反应理论模型进行同步或并发校准，将所有项目置于同一量表上。
在七个量表中增加了28个潜在新项目中的22个。为愤怒量表提出了推荐的简短形式，并修订了焦虑和抑郁症状量表的推荐简短形式。遗憾的是，我们在扩展身体功能项目库的测量范围方面并非特别成功。
本研究扩展了PROMIS儿科项目库，以添加新内容并扩大测量范围。使用项目反应理论，在不改变基本测量量表的情况下对项目库进行了修订和扩展。对于愤怒、焦虑和抑郁症状，我们成功添加了新内容，这可能使这些项目库更加强健和灵活。
