摘要
目的 编制冠心病患者健康信念量表,并对其信度和效度进行评价.方法 根据健康信念模式理论框架,结合文献资料及访谈法建立量表条目池,经研究小组讨论及专家评定后形成预试量表.通过方便抽样方法选取天津市某三甲综合医院的冠心病患者260例,并对其进行调查.采用探索性因素分析、信度分析、相关分析等对量表的信度和效度进行评价.结果 探索性因素分析共提取8个因子,各条目因子的负荷值为0.489～0.850,累积方差解释率为60.698％.各因子与量表总分的相关系数为0.811～0.876,各维度之间的相关系数为0.330～0.732.量表总的Cronbach α系数为0.802,5个因子的Cronbach α系数为0.684～0.834;量表总的重测信度系数为0.880,各因子重测信度系数为0.673～0.841.结论 冠心病健康信念量表具有良好的信度和效度,可以作为冠心病患者健康信念评估及干预的测量工具.
Objective To develop a scale for measuring CHD patients＇ health belief and to rectify its reliability and validity.Methods The primary items were obtained through reviewing literature and semi-structured interviewing with CHD patients.After team discussion and experts evaluation,the pretesting scale was developed.Two hundred and sixty subjects were recruited in the first study to finish the questionnaire by convenience sampling.The reliability and validity of this scale were tested by exploratory factor analysis,reliability analysis and correlation analysis.Results It was found that eight common factors extracted by exploratory factor analysis.Factor loading of each item ranged between 0.489 and 0.850.The 8 factors explained for 60.698% of total variance.The correlations between the subscales and the total scale were ranging from 0.811 to 0.876.The correlations between the subscales of the scale were ranging from 0.330 to 0.732.The Cronbach＇s α coefficients of the total scale was 0.802,and the subscales Cronbach＇s α coefficients were ranging from 0.684 to 0.834.Test-retest reliability was 0.880,and that of subscales were 0.673～0.841.Conclusions The newly developed coronary artery disease health belief scale has showed acceptable reliability and validity,which can be used as a useful tool for the assessment and intervention of patients＇ health belief.
