目的为PROMIS(R)儿科心理和生理应激体验测量提供心理测量学评价。方法通过两项研究，对2875名8-17岁儿童和2212名5-17岁儿童的父母进行心理和生理压力体验问卷调查。分析包括描述性统计、信度、因素分析、差异项目功能(DIF)和结构效度评估。使用项目反应理论对项目进行校准，以估计代表美国的项目参数。建议的八项和四项简短表格是为心理和身体压力体验题库的儿童报告和家长报告版本构建的。结果最终试题库是一维的，试题局部独立，不受DIF影响。心理压力库包括19个儿童报告条目和12个家长代理条目。身体压力库包括26个儿童报告条目和26个家长代理条目。所有仪器都有很强的内部一致性和重测可靠性，并提供对不同压力水平的准确估计。这些工具的结构效度通过已知群体比较和与传统测量的趋同得到了证明。结论患者报告结果测量信息系统(PROIS)的儿科心理和身体压力题库和简表提供了对儿童压力体验的有效、准确和有效的评估。
Objective To provide psychometric evaluation of the PROMIS (R) Pediatric Psychological and Physical Stress Experiences measures. Methods Across two studies, Psychological and Physical Stress Experiences items were administered to 2,875 children aged 8-17 years and 2,212 parents of children aged 5-17 years. Analyses included descriptive statistics, reliability, factor analysis, differential item functioning (DIF), and assessment of construct validity. Items were calibrated using item response theory to estimate item parameters representative of the United States. Recommended eight- and four-item short forms were constructed for child- and parent-report versions of the Psychological and Physical Stress Experiences item banks. Results Final item banks were unidimensional and items were locally independent and free from impactful DIF. Psychological Stress banks include 19 child-report and 12 parent-proxy items. Physical Stress banks include 26 child-report and 26 parent-proxy items. All instruments have strong internal consistency and retest-reliability, and provide precise estimates of varying stress levels. The instruments' construct validity was evidenced by known-group comparisons and convergence with legacy measures. Conclusions The Patient Reported Outcome Measurement Information System (PROMIS) Pediatric Psychological and Physical Stress item banks and short forms provide efficient, precise, and valid assessments of children's stress experiences.
