title: [Study on the model of effect evaluation in AIDS health education among junior middle school students in Hangzhou City].
abstract: OBJECTIVE
  To explore the scientific and standardized effect evaluation models of health education, to improve the effect evaluation quality.
  
  
  METHODS
  By the stratified cluster sampling method, 270 junior middle school students from six classes of two ordinary junior middle schools were included. The objectives were randomized into three groups, intervention group A (with health education intervention, two questionnaire survey before and after intervention), intervention group B (with health education intervention, one questionnaire survey after intervention), and control group C (only with general hygienic knowledge education, two questionnaire surveys before and after intervention) .
  
  
  RESULTS
  The increase of mean comprehensive score after intervention in intervention group A was significant compared to that before intervention, however, which was not significant in control group C. The mean comprehensive score after intervention in intervention group A was significantly higher than that in intervention group B and control group C, respectively. And the same circumstance existed between intervention group B and control group C. The difference in the knowing rate for every specific item was not significantly different between intervention group A and control group C before intervention. In intervention group A, the knowing rates for mass specific items were significantly increased before and after intervention. However, in control group C, the knowing rate for only one specific item was significantly increased before and after intervention. After intervention, the knowing rates of several specific items in intervention group A was significantly higher than those in intervention group B and control group C, respectively. And the same circumstance existed between intervention group B and control group C .
  
  
  CONCLUSIONS
  The usage of the same questionnaire to the same group may result in overestimating the effect of health education.
