abstract: OBJECTIVE
  To test the reliability and validity of a questionnaire on knowledge-attitude-practice on serum lipids.
  
  
  METHODS
  Based on the data investigated with this questionnaire from 158 persons at the age of over 40 years and the test-retest data from 60 persons. The reliability of the questionnaire was assessed by homogeneity reliability and test-retest reliability. The validity was assessed through correlation analysis, factor analysis and analysis of variance et al.
  
  
  RESULTS
  The Cronbach's alpha coefficient were more than 0.7 and retest coefficients were more than 0.8. The Pearson correlate coefficients of all the items to their dimensions were more than 0.61. Factor analysis conformed to logic relation, and the cumulative variance were 64.111%. The persons KAP on serum lipids was different in education and gender.
  
  
  CONCLUSIONS
