精神疾病内在病耻感调查表在精神分裂症患者中的信度和效度

目的:评价精神疾病内在病耻感调查表(internalized stigma of mental illness inventory,ISMI)在精神分裂症患者中的信度和效度。方法:选择慢性稳定期精神分裂症患者191例,自行完成ISMI量表及病耻感总体评价,随机抽取42例患者于2周后复测ISMI。使用SPSS软件对量表的信度、效度进行分析。结果:被试者ISMI总分平均为(65.12±12.86)分;复测信度相关性系数为0.87;分半信度系数为0.85;所有29条目Cronbach α系数为0.94。平行效度相关系数为0.66;结构效度采用因子分析法,经方差最大旋转后结果揭示主成分累计贡献率57.80%。结论:ISMI量表对评定精神分裂症患者的病耻感有较好的信度和效度。

The reliability and validity of internalized stigma of mental illness inventory in patients with schizophrenia

Objective:To assess the reliability and validity of internalized stigma of mental illness inventory(ISMI) in patients with schizophrenia.Method:One 191 chronic schizophrenia patients were enrolled.All of them were requested to fill out ISMI and general questionnaire of stigma by themselves.42 patients were selected randomly and retested after 2 weeks.The reliability and construct validity were calculated by SPSS.Results:The mean score of total ISMI was(65.12±12.86).The coefficient of test-retest for the total score of ISMI,split-half coefficient and Cronbach’s α coefficient were 0.87,0.85,0.94 respectively.Its parallel validity was 0.66.The construct validity was examined by factor analysis and cumulative variance of principal components was 57.80%.Conclusion:The results showed that ISMI had good reliability and high validity.
