New resilience instrument for family caregivers in cancer: a multidimensional item response theory analysis

Abstract

Objective Resilience instruments specific to family caregivers (FCs) in cancer are limited. This study was designed to validate the 10-item Resilience Scale Specific to Cancer (RS-SC-10) in FCs using multidimensional item response theory (MIRT) analysis. Methods 382 FCs were enrolled from Be Resilient to Cancer Program (BRCP) and administered with RS-SC-10 and 36-item Short Form Health Survey (SF-36). MIRT was performed to evaluate item parameters while Generalized Additive Model (GAM) and Latent Profile Analysis (LPA) were performed to test the non-linear relationship between resilience (RS-SC-10) and Quality of Life (QoL, SF-36). Results RS-SC-10 retained 10 items with high multidimensional discrimination, monotonous thresholds and its original two-factor structure (Generic and Shift-Persist). Four latent resilience subgroups were identified and a non-linear dose–response pattern between resilience and QoL was confirmed (per-SD increase OR = 1.62, 95% CI 1.16–2.13, p = 0.0019). Conclusion RS-SC-10 is a brief and suitable resilience instrument for FCs in cancer. The resilience screening of patients and FCs can be performed simultaneously in clinical practice.

Validation of the Chinese version of the resilience scale for the oldest-old

“…Considering that China is a multiethnic country with a large population, it is recommended that a multilevel and multicenter study be conducted using a random sampling method, that the sample size is further expanded to improve the reliability and applicability of the scale assessment and that it be revised continuously to make it mature. The current study is based on the Classical Theory Test (CTT), and future studies should use a combination of the Classical Theory Test (CTT) and Item Response Theory (IRT) to provide additional information, such as item difficulty and discrimination, which will help address the factor-related issues in this study (Ye et al, 2018b(Ye et al, , 2019Liang et al, 2021). A limitation of the current study is that no precise distinction was made as to whether the RSO was a state or trait scale (Ye et al, 2020).…”

Measuring resilience by cognitive diagnosis models and its prediction of 6-month quality of life in Be Resilient to Breast Cancer (BRBC)

“…RS-SC is rated based on a five-point Likert scale, with higher scores indicating higher resilience levels (score ranges from 25 to 125). In this study, a short-form of 10-item RS-SC (RS-SC-10) was administered ( 21 – 23 ). RS-SC and RS-SC-10 were attached in the Supplementary material .…”

“…First, based on the two-factor structure of RS-SC-10 in our previous research ( 21 – 23 ), two theory-based Q matrix were developed for validating the number of item attributes and detecting the misidentified elements, including a bifactor Q-matrix and a non-bifactor one ( Figures 2A, B ). A cell with the value of 1 indicates that the corresponding item attribute is captured by the corresponding item.…”

Associations among neuroticism, self-efficacy, resilience and psychological distress in freshman nursing students: a cross-sectional study in China

“…Therefore, new resilience instruments specific to medical students should be developed, which has been highlighted in other resilience-based studies. [45][46][47][48][49][50] Fourth, several potential confounders, such as social support, hope and family function were not considered in the moderated mediation model due to heavy scale burden; this may have had an impact on the association estimation.…”
