title: [Study on quality of schistosomiasis knowledge questionnaire of primary pupils in Wuxing Farm School of Nanchang City].
abstract: OBJECTIVE
  To evaluate the quality of a questionnaire about schistosomiasis knowledge of the pupils in Wuxing Farm School in Nanchang City.
  
  
  METHODS
  The quality of the questionnaire about schistosomiasis knowledge was evaluated through reliability, validity, discrimination and some other indexes.
  
  
  RESULTS
  The entire reliability of the survey was high with its split-half reliability of 0.68 and Cronbach alpha coefficient of 0.627. The content validity was good: the exploratory factor analysis revealed 5 common factors from 13 questionnaire items which could account for 58.3% of the total variance; the confirmatory factor analysis revealed that the construct validity of 13 questionnaire items was better than that of the whole questionnaire (17 items in total) (chi2 = 90.5, df = 65, GFI = 0.92, AGFI = 0.88, NFI = 0.58, CFI = 0.817, RMSEA = 0.049); the difficulty and the discrimination coefficients of the questionnaire were suitable, being 0.595 and 0.42 respectively.
  
  
  CONCLUSIONS
  The questionnaire is qualified in general, but parts of the items need to be revised to perfect.
