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,SFHBMS),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(χ~2/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。
Objective To simplify the Chinese version of the Champion health belief model scale (CHBMS) in order to make it easier to measure the health beliefs of stroke patients. Methods Entries of 88 Chinese CHBMS questionnaires were analyzed and revised by expert consultation method and simplified into short form fealth belief model scale (SFHBMS) Stroke patients questionnaire, using SPSS 17.0 and Mplus 7.0 software to test the reliability and validity of the summary table. Results The item-level content validity index (I-CVI) of the simplified scale was 0.97 on an average, and the sale-content validity index / universal agreement (S CVI / UA and sale-content validity index / average (S-CVI / Ave) were 0.85 and 0.97, respectively; the homogeneity reliability, half-confidence, Respectively. The normalized chi-square (χ ~ 2 / df) of the confirmatory factor analysis model was 1.642, the comparative fit index (CFI) was 0.939, the Tucker-Lewis index -liwis 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, indicating that the model was accurate Fitting data. The validity of the standard and full scale scales was 0.956. SF-HBMS can distinguish the level of health belief of patients with different educational level (t = -2.282, P = 0.023), and the discriminant validity is better. Conclusion SF-HBMS has good reliability and validity, which can be used to measure the level of health belief in stroke patients.
