Abstract

Background and Objective: Resilience refers to a protective factor that reduces stress in people with multiple sclerosis (PwMS). Given the significance of this issue, the present research aimed to assess the validity and reliability of the Connor-Davidson Resilience Scale (CD-RISC) in PwMS. Materials and Methods: The present cross-sectional study aimed to assess the psychometric properties of CD-RISC in the statistical population of Guilan MS Society (GMSS). In this study, 442 people with MS participated and responded to CD-RISC in an online survey. The data were analyzed in SPSS (version 23) and Amos (version 21) software packages. Results: The confirmatory factor analysis results of the first stage with five factors revealed that 25 CD-RISC items benefited from high factor load and good fit indices were reported (ꭕ2=605.55; df=265; P-Value=.0001; ꭕ2/df=2.28; GFI=.88; CFI=.93; TLI=.92; RMR=.06; RMSEA=.05); therefore, CD-RISC has good construct validity. Cronbach’s alpha coefficients for the whole scale and subscales were calculated at 0.94 and 0.71-0.89, respectively, indicating the optimal reliability of CD-RISC in PwMS. Conclusions: The current study presented evidence for CD-RISC validity and reliability. Further studies are recommended to ensure the psychometric properties of this scale in other chronic patients.
康诺-戴维森弹性量表在多发性硬化症患者中的效度和信度:伊朗的一项心理测量学研究
背景和目的:韧性是指一种保护性因素,可以减轻多发性硬化症患者的压力。鉴于这一问题的重要性,本研究旨在评估康纳·戴维森弹性量表(CD-RISC)在普华永道会计师事务所的有效性和可靠性。材料和方法:本横断面研究旨在评估桂兰MS学会(GMSS)统计人群中CD-RISC的心理测量特性。在这项研究中,442名MS患者参与了一项在线调查,并对CD-RISC做出了回应。数据在SPSS(23版)和Amos(21版)软件包中进行分析。结果:第一阶段5个因素的验证性因子分析结果显示,25个CD-RISC项目受益于高因子负荷和良好的拟合指数(ꭕ2=605.55;df=265;P值=.0001;ꭕ2/df=2.28;GFI=.88;CFI=.93;TLI=.92;RMR=.06;RMSEA=.05);因此,CD-RISC具有良好的结构有效性。全量表和分量表的Cronbachα系数分别为0.94和0.71-0.89,表明CD-RISC在PwMS中的最佳可靠性。结论:本研究为CD-RISC的有效性和可靠性提供了证据。建议进行进一步的研究,以确保该量表在其他慢性患者中的心理测量特性。
