Development and psychometric analysis of the 10-item resilience scale specific to cancer: A multidimensional item response theory analysis

摘要

Purpose: Resilience is an important concept in the cancer literature and is a salient indicator of cancer survivorship. Classic theory test (CTT) and item response theory (IRT) were performed to develop and validate the 25-item Resilience Scale Specific to Cancer (RS-SC). This study was designed to develop and validate a short form of RS-SC (RS-SC-10) with a multidimensional IRT (MIRT) analysis.
