Study on reliability and validity of quantitative evaluation table for food hygiene of catering industry in Guangdong Province

In order to improve the level of the administration and health inspection of the food services, and provide the health inspectors with a scientific, useful, and quantified appraising tool, 5 food services in Guangzhou and Huizhou were sele cted and evaluated with an appraising table sheet designed by the authors. Befo r e the fieldwork, the randomized complete-block design was conducted to test the validity and the reliability of the appraising table sheet. Five inspectors eva luated 5 selected food services with the appraising table sheet repeatedly. The mean points of the 5 services were 71.48, 72.80, 77.9, 71.76 and 71.23. The differences among the inspectors were not significant (ANOVA P>0.05). The coefficient of intergroup correlation was 0.94. The points of the 5 selected s ervices were 92.24, 86.02, 73.72, 63.06 and 50.58(ANOVA P<0.01) respe ctively. Thus, it can be seen that the validity and the reliability of the table are perfect.
