This cross-sectional study aimed to explore the knowledge, attitudes and behaviors of household waste separation among residents, to study the factors affecting household waste disposal behavior of the residents, and to study the ability of prediction of household waste disposal behavior among the residents in Nong Ka Tha subdistrict, Nakhon Thai district, Phitsanulok province. The researcher gathered all data from the studied population of 180 households via a survey, and then analyzed the information through descriptive statistics, i.e. Eta, Pearson correlation and stepwise multiple regression analyses. The results of showed a high level of knowledge of waste segregation at 67.20% of households. The attitude towards waste segregation was 60 %, while waste segregation behavior was 88.30 %. Factors affecting waste segregation behaviors, i.e. receiving waste segregation suggestions from household members and their neighbors (beta = 0.337), attitudes of household waste segregation (beta = 0.369), the number using recycling services (0.232), and obtaining information about household waste segregation (0.148), together predicted the behavioral household waste segregation at 41.60 %, with statistically significant level of 0.05. The outcomes from this study may be beneficial in applying to waste management and finding solutions for household waste segregation and a positive impact on households.
