BACKGROUND AND PURPOSE
The purpose of this study was to evaluate Mishel Uncertainty in Illness Scale-Community (MUIS-C), used to gauge level of uncertainty among baby boomers with hepatitis C virus (HCV) infection, as a reliable two-factor instrument.
METHODS
A CFA was conducted to test MUIS-C. There were minor deviations from normality. Subsequently, 130 participants were used to examine the factor structure and the model fit. A robust maximum likelihood (ML) estimation using the Wishart distribution was implemented in R version 3.3.1.
RESULTS
A very good model fit was obtained ((101) = 118.32, = .115, = 0.977, = 0.983, = 0.036, 90%(0.000, 0.061), and = 0.057). All indicators showed significant positive factor loadings, with standardized coefficients ranging from 0.511 to 0.868.
CONCLUSIONS
The MUIS-C was a reliable two-factor instrument and suitable for use as such in baby boomer population with HCV.
背景与目的
本研究旨在评估用于评估丙型肝炎病毒（HCV）感染的婴儿潮一代患者的不确定性水平的Mishel 疾病不确定感量表-社区版（MUIS-C），作为一种可靠的两因素工具。
方法
采用 CFA 对 MUIS-C 进行检验。存在轻微的正态性偏差。随后，使用 130 名参与者来检验因子结构和模型拟合度。在 R 版本 3.3.1 中使用 Wishart 分布实施稳健最大似然（ML）估计。
结果
获得了非常好的模型拟合度（(101) = 118.32， =.115， = 0.977， = 0.983， = 0.036，90%（0.000，0.061）， = 0.057）。所有指标均显示出显著的正因子负荷，标准化系数范围为 0.511 至 0.868。
结论
MUIS-C 是一种可靠的两因素工具，适用于 HCV 婴儿潮一代人群。
