摘　　要：目的评价家庭负担量表（FBS）应用于血吸虫病患者家庭负担调查的信度、效度及敏感性。方法用FBS对224例血吸虫病患者进行现场调查。采用Cronbach’s α和折半信度评价量表的信度，因子分析法评价量表的效度，用方差分析比较不同收入水平患者的评分以评价量表的敏感性。结果量表的内容一致性较高，整个量表的Cronbach’s α和折半信度分别为0．874和0．939；量表各个维度的Cronbach’s α和折半信度大多在0．70以上；采用因子分析法，共提取6个公因子，累计贡献率为66．76％，基本证实了其结构效度；该量表能够区分不同收入水平患者家庭负担之间的差异（P〈0．001），证实其敏感性较好。结论FBS具有较好的信度、效度及敏感性，可用于血吸虫病患者的家庭负担调查。Objective To evaluate the reliability, validity and sensitivity of a Family Burden Scale （FBS） of disease used on schistosomiasis. Methods 224 schistosomiasis patients were investigated, using the FBS. Reliability was estimated by Cronbach＇ s α coefficient and split-half reliability. Validity was tested by factor analysis. Sensitivity was evaluated by comparison of patients with different income levels. Results The Cronbach＇s α coefficient was 0. 874 and split-half reliability was 0. 939 for FBS, respectively. Most values of Cronbach＇s α and split-half reliability for each component of scale were above 0.70. Construct validity was appraised by factor analysis, and 6 factors were identified. These factors could explain 66.76 % of the total variance. Patients with different income levels showed significant difference in terms of family burden for schistosomiasis （P〈 0.001 ）. Conclusion This FBS appeared to have satisfactory reliability, validity and sensitivity and could be used in evaluating family burden of schistosomiasis patients.
