参与和自主性测评问卷在精神分裂症病人中的信度及效度评价

摘要

[目的]评价参与和自主性测评问卷(IPA)在我国精神分裂症病人中的适用性.[方法]采用方便取样方法,选择符合纳入标准的精神分裂症病人185例,对IPA进行测试.[结果]IPA-Ⅰ问卷条目与总分相关系数为0.515~0.769,IPA-Ⅱ问卷条目与总分相关系数为0.701~0.794,均 P<0.01;IPA-Ⅰ问卷内部Cronbach's α系数为0.962,各维度Cronbach's α系数为0.818~0.929;IPA-Ⅱ问卷内部Cronbach's α系数为0.883;量表各条目内容效度指数(CVI)为0.830~1.000,全部条目的平均CVI为0.959;因子分析提取了6个公因子,6个因子方差的累积贡献率为73.881%,所有条目均被提取,并且各条目在所提取维度具有较大因子载荷(>0.4).[结论]IPA信度及效度较好,可以用于评价精神分裂症病人社会参与和自主性水平.%Objective:To evaluate the applicability of impact on participation and autonomy questionnaire(IPA) in schizophrenic patients in China.Methods:A total of 185 patients with schizophrenia and conforming to the in-clusion criteria were selected by IPA using the convenient sampling method and to test IPA.Results:The corre-lation coefficient of IPA-I questionnaire and items total score was 0.515~0.769,and the correlation coefficient of IPA-II questionnaire and total score was 0.701~0.794,P<0.01.The internal Cronbach's alpha coefficient of the IPA-I questionnaire was 0.962,and the Cronbach's alpha coefficient of all dimension was 0.818~0.929;T he internal Cronbach's alpha coefficient of the IPA-II questionnaire was 0.883,and the content validity index(CVI)of the scale was 0.830~1.000,and the average CVI of all items was 0.959.Factor analysis extracted 6 common factors,the cumulative contribution rate of 6 factor variance was 73.881%,and all entries were extracted,and each item had larger factor load in the extracted dimensions(>0.4).Conclusions:IPA had good reliability and validity,and could be used to evaluate the level of social participation and autonomy of schizophrenic patients.
