慢性疾病病耻感量表-8在脑卒中患者中应用的信效度研究

A study of reliability and validity of the stigma scale for chronic illness 8-item version(SSCI-8) in stroke patients

目的:调查慢性疾病病耻感量表-8(SSCI-8)在脑卒中患者中的信效度。方法:采用便利抽样的方法抽取204名社区脑卒中患者进行调查,进行信效度检验。结果:项目分析显示中文版SSCI-8能够鉴别高分组和低分组(P<0.01),各条目得分与SSCI-8总分的相关系数为0.611~0.843;与抑郁、日常生活能力、SF-12心理维度及生理维度的相关系数为0.537、-0.440、-0.450、-0.441(P<0.01)。探索性因子分析提取2个公因子,累计方差贡献率为75.39%,各条目在其相应维度上有较高的因子负荷,验证性因子分析结果显示,各拟合指数均在可接受范围内,SSCI-8的Cronbach’sα系数为0.892,重测信度为0.809。结论:中文版SSCI-8在脑卒中具有较好的信效度,可在脑卒中及神经系统疾病病耻感的相关研究中使用。

Objective:To investigate the reliability and validity of Chinese version of stigma scale for chronic illness-8 in stroke patients.Methods:A total of 204 patients with stroke in community were recruited using convenience sampling method to test the reliability and validity.Results:Item analysis showed that the Chinese version of SSCI-8 could discriminate the high score group from the low group(P<0.01).Correlation coefficient between the scores of each item and the total score was 0.611~0.843.As for the association between the SSCI and depression,activity of daily living,psychological dimensionandphysical dimensions of SF-12,Pearson’s correlation was 0.537、-0.440、-0.450、-0.441(P<0.01).From exploratory factor analysis,2 factors were generated with an accumulated variance contribution of 75.39%,and each item had high factor loading of the corresponding dimension.Confirmatory factor analysis indicated that the fitting index were all in acceptable level.Internal consistency was confirmed by Cronbach’sαcoefficient of 0.892,the test-retest interclass correlation of total scale was both 0.809.Conclusion:The Chinese version of SSCI-8 showed good reliability and validity,and could be used in the research of stigma in neurological disorder diseases in China.
