The pediatric patient-reported outcomes measurement information system (PROMIS) was developed to provide self-reported item banks and short forms for children and adolescents (aged 8-17 years) experiencing a chronic illness to assess their quality of life and symptoms. The pediatric PROMIS short forms have been translated into Chinese and applied in children with cancer in China. This study aimed to describe psychometric properties of the Anxiety and Depression measures.
A total of 232 children and adolescents with cancer were recruited in hospital-based inpatient and outpatient clinics. Eight Chinese versions of pediatric PROMIS (C-Ped-PROMIS) measures were administered. Categorical confirmatory factor analysis (CCFA) were conducted to evaluate scale dimensionality and item local dependence of the C-Ped-PROMIS Anxiety and Depression items. Multiple indicator multiple cause models were used to analyze differential item functioning (DIF), item response theory parameters were calculated, and test information against T scores was reported for each measure.
The results of the CCFA confirmed that both C-Ped-PROMIS Anxiety and Depression scales appropriately measure the theoretical constructs as designed. No significant DIF was found for the items of the two scales according to age and gender. Both scales have high test reliability as long as their T scores are not on the low or high extremes.
The pediatric PROMIS Anxiety and Depression measures were developed to provide efficient and flexible assessment of emotional distress domains. Our results provide evidence that the two C-Ped-PROMIS measures can be readily applied to measure anxious and depressive symptoms in Chinese children with cancer.
儿童患者报告结局测量信息系统（PROMIS）旨在为患有慢性病的儿童和青少年（8至17岁）提供自我报告的条目库和简表，以评估他们的生活质量和症状。儿童PROMIS简表已被翻译成中文并应用于中国的癌症患儿。本研究旨在描述焦虑和抑郁测量工具的心理测量特性。
在医院的住院部和门诊部共招募了232名癌症患儿和青少年。采用了8种中文版儿童PROMIS（C-Ped-PROMIS）测量工具。进行了分类验证性因素分析（CCFA），以评估C-Ped-PROMIS焦虑和抑郁条目的量表维度和条目局部依赖性。使用多指标多原因模型分析差异项目功能（DIF），计算项目反应理论参数，并报告每种测量工具相对于T分数的测试信息。
CCFA结果证实，C-Ped-PROMIS焦虑和抑郁量表均能如设计的那样适当测量理论结构。根据年龄和性别，两个量表的条目均未发现显著的DIF。只要T分数不在极低或极高的极端值，两个量表都具有较高的测试信度。
儿童PROMIS焦虑和抑郁测量工具旨在对情绪困扰领域进行高效、灵活的评估。我们的结果提供了证据，表明两种C-Ped-PROMIS测量工具可随时用于测量中国癌症患儿的焦虑和抑郁症状。
