Classic theory test has been used to develop and validate the 25-item Resilience Scale Specific to Cancer (RS-SC) in Chinese patients with cancer. This study was designed to provide additional information about the discriminative value of the individual items tested with an item response theory analysis.
A two-parameter graded response model was performed to examine whether any of the items of the RS-SC exhibited problems with the ordering and steps of thresholds, as well as the ability of items to discriminate patients with different resilience levels using item characteristic curves.
A sample of 214 Chinese patients with cancer diagnosis was analyzed. The established three-dimension structure of the RS-SC was confirmed. Several items showed problematic thresholds or discrimination ability and require further revision.
Some problematic items should be refined and a short-form of RS-SC maybe feasible in clinical settings in order to reduce burden on patients. However, the generalizability of these findings warrants further investigations.
经典理论测试已被用于开发和验证针对中国癌症患者的 25 项特定于癌症的韧性量表（RS-SC）。本研究旨在通过项目反应理论分析提供有关个体项目测试的区分价值的更多信息。
使用双参数等级反应模型来检查 RS-SC 的任何项目是否存在排序和阈值步骤问题，以及使用项目特征曲线来衡量项目区分不同韧性水平患者的能力。
对 214 名中国癌症患者的样本进行了分析。证实了 RS-SC 的三维结构。一些项目显示出有问题的阈值或区分能力，需要进一步修订。
为了减轻患者负担，一些有问题的项目应该进行细化，并且 RS-SC 的简短形式可能在临床环境中是可行的。但是，这些发现的普遍性需要进一步研究。
