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

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’s α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。

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

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’s α coefficient 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.
