目的对高血压生活质量问卷(MINICHAL)在我国高校职工高血压患者中应用信度和效度进行分析研究,为高校职业场所职工高血压患者的生活质量评价提供有效的工具支持。方法从国内8所高校在职职工中筛查出681例高血压患者进行了高血压生活质量问卷(MINICHAL)调查,使用Cronbach’s alpha和Pearson相关系数评估量表MINICHAL信度;因子分析法评价该问卷的结构效度。结果信度分析显示,MINICHAL问卷的内部一致性α信度系数为0.825,因子1(精神维度)Cronbach’sα值为0.814,因子2(身体维度)Cronbach’sα值为0.816;结构效度采用因子分析共提取两个因子,方差累计贡献率为40.171%,但问卷中条目10本应归为因子1(精神维度),但在本研究中条目10在因子分析中被提取归为至因子2(身体维度)。结论 MINICHAL问卷具有良好的信度和效度,适用于评价高校职工高血压患者的生活质量。
Objective To analyze and evaluate the reliability and validity of MINICHAL in hypertension among college staff in our country and provide an effective tool to evaluate the quality of life of hypertensive patients in vocational college. Methods A total of 681 hypertensive patients were screened out from 8 domestic colleges and universities in the workforce for the survey of quality of life in hypertension (MINICHAL), using Cronbach’s alpha and Pearson correlation coefficient to assess the scale MINICHAL reliability; factor analysis to evaluate the questionnaire Structural validity. Results The reliability analysis showed that the internal consistency α reliability coefficient of MINICHAL questionnaire was 0.825, the Cronbach’s α of factor 1 (mental dimension) was 0.814, and the Cronbach’s α of factor 2 (body dimension) was 0.816. The structural validity was evaluated by factor Two factors were extracted from the analysis, and the cumulative contribution rate of variance was 40.171%. However, item 10 in the questionnaire should be classified as factor 1 (mental dimension), but item 10 was extracted in factor analysis as factor 2 Body dimension). Conclusion The MINICHAL questionnaire has good reliability and validity and is suitable for evaluating the quality of life of college staff with hypertension.
