ABSTRACT
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.
