Effect of Knowledge and Attitudes for Solid Waste Management Program in Khao Ngam Subdistrict, Wang Noi District, Phra Nakhon Si Ayutthaya Province

Abstract

The purpose of this quasi-experimental research was to investigate the effect of a program to improve knowledge and attitudes for solid waste management in Khao Ngam subdistrict, Wang Noi district, Phra Nakhon Si Ayutthaya province. Samples were 80 persons drawn from residences in this area with 40 persons randomly assigned to experimental and the control groups equally. The experimental group was provided with knowledge and attitudes for solid waste management program for 3 weeks, with 1 session each week. The control group was provided with manual and video clips on this issue. Data were analyzed using frequencies, percentages, means, standard deviations, paired sample t-test and independent sample t-test at p-value=0.05. The results showed that knowledge and attitude levels before attending the program were both at a moderate level (at 47.5% and 95.0% respectively). After attending the program, both their knowledge and attitude levels increased to a high level (65.0%) and a good level (80.0%). Average knowledge and attitude scores comparing between before and after attending the program were significantly higher at p-value<0.05. When comparing with the control group, it was found that average knowledge and attitude levels of the experimental group after attending the program was significantly higher than those in the control group at 65.0 and 80.0 percent, respectively at p-value<0.05). It can be concluded that the program was effective in changing knowledge and attitude levels and can be used to promote solid waste management behavior in the future.
