摘要: 目的 为了更简便地测量脑卒中患者的健康信念水平,将Champion健康信念量表 (the champion health belief model scale,CHBMS)中文版进行简化。方法 对88例患者的CHBMS健康信念量表的完整中文版问卷进行条目分析,并采用专家咨询法进行修订并简化为健康信念简表(short form fealth belief model scale,SF-HBMS),并对235例脑卒中患者问卷调查,采用SPSS 17.0及Mplus 7.0软件检验简表的信度和效度。结果 简化后的量表的条目水平内容效度指数(item-level content validity index,I-CVI)平均为0.97,量表水平的全体一致内容效度指数(sale-content validity index/universal agreement,S-CVI/UA)和平均内容效度指数(sale-content validity index/ average,S-CVI/Ave)分别为0.85、0.97;总量表的同质性信度、分半信度、重测信度分别为0.835、0.779、0.811;验证性因子分析模型的常态化卡方值(χ2/df)为1.642,比较拟合指数(comparative fit index,CFI)为0.939,Tucker-Lewis 指数(tucker-lewis index,TLI)为0.926,标准化残差均方根(standardized root mean square residual,SRMR)为0.062,近似误差平方根(root mean square error of approximation,RMSEA)为0.052,P=0.361,说明模型精确拟合数据。简表与完整版量表的效标效度为0.956。SF-HBMS能区分不同文化程度患者的健康信念水平(t=-2.282,P=0.023),区分效度较好。结论 SF-HBMS具有较好的信度和效度,可用于测量脑卒中患者的健康信念水平。Abstract: Objective To simplify the Chinese version of the champion health belief model scale (CHBMS). Methods The Chinese version of CHBMS was revised using item analysis and expert consultation methods. A total of 235 stroke patients were recruited and investigated with short form health belief model scale (SF-HBMS). SPSS 17.0 and Mplus 7.0 software were used to test the reliability and validity. Results The item-level content validity index(I-CVI)was 0.97. The Sale-CVI/ universal agreement (S-CVI/UA) was 0.85. The Sale-CVI/average (S-CVI/Ave) was 0.97. The Cronbach's α was 0.835. The split-half reliability was 0.779. The test-retest reliability was 0.811. The confirmatory factor analysis was performed to test the construct validity. The χ2/ df was 1.642. The comparative fit index (CFI) was 0.939. The tucker-lewis index (TLI) was 0.926. The standardized root mean square residual (SRMR) was 0.062; the root mean square error of approximation(RMSEA)was 0.052, P=0.361, which all demonstrated that six dimensions and their items were all consistent and fitted with its theoretical structure. The criterion-related validity was 0.956. It could distinguish the difference of health belief among patients with different educational level (t=-2.282,P=0.023) and had desired discriminative validity. Conclusions The SF-HBMS has satisfactory reliability and validity, and can be used to assess the level of health belief for stroke patients.
