Effects of Food Sanitation Behavior Modification Program of Food Stallholders in Thonburi Bangkok

Abstract

     This quasi-experimental research aimed to compare food sanitation knowledge, attitudes towards food sanitation behavior, perceived ability to perform food sanitation behavior, intention to engage in food sanitation behavior, and food sanitation behavior among street food vendors before and after participating in the program between the experimental and control groups, as well as to assess the street food vending stalls. The sample consisted of 60 participants, with 30 in the experimental group and 30 in the control group, selected through purposive sampling based on specific criteria. The experimental group participated in the food sanitation behavior modification program for 4 weeks. Data were collected using a researcher-developed questionnaire, which had been tested for acceptable validity and reliability, and a food sanitation standard assessment. The data were analyzed using statistics such as frequency, percentage, mean, standard deviation, and hypothesis testing with Paired Sample t-test and Independent t-test.
     The results showed that after participating in the program, the experimental group had significantly higher mean scores in food sanitation knowledge, attitudes towards food sanitation behavior, perceived ability to perform food sanitation behavior, intention to engage in food sanitation behavior, and food sanitation behavior compared to before the experiment and the control group.
