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(P<0.05)。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。
Objective To evaluate the reliability and validity of the questionnaire on health needs of patients with pulmonary tuberculosis among floating population. Methods Pulmonary tuberculosis patients diagnosed with newly diagnosed migrant population and control group were measured with the self-developed health needs questionnaire of pulmonary tuberculosis patients. The Cronbach’α coefficient and the semi-reliability coefficient were used to evaluate the reliability of the scale. The factor analysis was used to evaluate the validity of the scale. Group t-test was used to compare the scores of the case group and the control group to evaluate the sensitivity of the scale. Results The Cronbach’α coefficient of health needs of patients with tuberculosis was 0.625 3, and the factors with more than 1 eigenvalue were 12, accounting for 72.4% of total variance. The scores of all TB patients in floating population were higher than those in control group (P < 0.05). Conclusion The reliability and validity of the questionnaire on health needs of migrant patients with pulmonary tuberculosis is poor, but the sensitivity is high. Scale factor design and entry organization to be further revised.
