OBJECTIVE
Little is known about the measurement invariance (MI) of resilience instruments in cancer care. This study was designed to examine MI of 10-Item Resilience Scale (RS-SC-10) in Americans and Chinese with cancer using propensity score-based multidimensional item response theory (MIRT) analysis.
METHODS
A sample of 924 patients were enrolled in the Be Resilient to Cancer trial involving 1 hospital in America and 3 hospitals in China. Data were collected from the RS-SC-10 and Hospital Anxiety and Depression Scale. Propensity score matching and MIRT were performed to evaluate Differential Item Function. Integrated Discrimination Improvement and Net Reclassification Improvement were used to indirectly estimate the MI through incremental prediction ability of MIRT-based score over total score.
RESULTS
RS-SC-10 retained 10 items with monotonous thresholds and its original two-factor structure. Nonuniform Differential Item Function was recognized in Item 4 ( = 0.0011, Δ%β1 = 4.15%) and Item 8 ( = 0.0017, Δ%β1 = 5.99%). Net Reclassification Improvement ranged from 9.04% to 35.01%, and Integrated Discrimination Improvement ranged from 8.82% to 20.60%.
CONCLUSIONS
Although partial MI has been identified between Americans and Chinese, RS-SC-10 remains a critical indicator to emotional distress in cancer care.
目的
关于癌症护理中复原力工具的测量不变性（MI），我们所知甚少。本研究旨在使用基于倾向得分的多维项目反应理论（MIRT）分析，检验美国和中国癌症患者中10项复原力量表（RS-SC-10）的测量不变性。
方法
924名患者参与了“抗击癌症”试验，该试验涉及美国1家医院和中国3家医院。数据收集自RS-SC-10和医院焦虑抑郁量表。进行倾向得分匹配和MIRT以评估项目功能差异。综合判别改善和净重新分类改善用于通过基于MIRT的分数相对于总分的增量预测能力间接估计测量不变性。
结果
RS-SC-10保留了10个具有单调阈值的项目及其原始的双因素结构。在项目4（p = 0.0011，Δ%β1 = 4.15%）和项目8（p = 0.0017，Δ%β1 = 5.99%）中发现了非均匀项目功能差异。净重新分类改善范围为9.04%至35.01%，综合判别改善范围为8.82%至20.60%。
结论
尽管已确定美国人和中国人之间存在部分测量不变性，但RS-SC-10仍然是癌症护理中情绪困扰的关键指标。
