流动人口肺结核患者健康需求量表的信度、效度及敏感性评价

目的评价流动人口肺结核患者健康需求量表的信度与效度。方法用自行研制的肺结核患者健康需求量表对确诊的初治流动人口肺结核患者和对照组进行测量。采用Cronbach’α系数和分半信度系数评价量表的信度,因子分析评价量表的效度,成组t检验比较病例组和对照组的评分以评价量表的敏感性。结果肺结核患者健康需求量表的Cronbach’α系数为0.625 3,特征根大于1的因子有12个,可解释总变异量的72.4%,流动人口肺结核患者各项得分均高于对照组(P0.05)。结论流动人口肺结核患者健康需求量表的信度和效度欠佳,但敏感性较高。量表的因子设计与条目组织有待进一步修订。

Evaluation on the reliability,validity and sensitivity of health needs scale for floating population with TB

Objective To evaluate the reliability,validity and sensitivity of health needs scale for floating population with TB. Methods All subjects were interviewed by using health needs scale.Reliability was analyzed by using Cronbach＇α and split-half reliability coefficients.Validity was tested by factor analysis.Sensitivity was evaluated by comparison of experimental group and control group. Results The Cronbach＇ α of health needs scale α 0.625 3 and 12 factors are above 1,which can explain 72.4% total variance.All scores of experimental group were higher than that of control group（P0.05）. Conclusions The health needs for floating population with TB was a valid tool for assessment of TB cases health needs but the scale of reliability and validity were not very good.The sensitivity for scale was better.The scale should require slight modification in the future.
