Abstract

This quasi-experimental study aimed to examine the effects of 3Rs program on knowledge, motivation, and behavior in household waste management of people in Khoksi Subdistrict, Sawang Daen Din District, Sakon Nakhon Province.  The study sample consisted of household representatives, assigned to an experimental group and a control group, with 50 participants in each group. This study in March  to  May  2024. The experimental group received the 3Rs program, which was designed based on the 3Rs principles and applied theories of The Information-Motivation-Behavioral Skill Model and Self-Efficacy Theory. Data collection tools included a questionnaire and household waste recording form. Data were analyzed using descriptive statistics, Paired-Samples T-Test, Independent-Samples T-Test, and Repeated-Measures ANOVA.

The research results found that after participating in the 3Rs program, the experimental group showed statistically significant improvements (p-value < 0.001) in knowledge, motivation, self-efficacy, and household solid waste management behavior based on the 3Rs principles, compared both to their baseline and to the control group. Furthermore, after the intervention and during the follow-up period, the amount of household solid waste in the experimental group significantly decreased (p-value < 0.001) compared to both before the intervention and to the control group.        

Therefore, these principles should be appropriately applied in each area to reduce household and community waste in the future.
