This is a quasi-experimental study aimed to assess the effectiveness of Tamon’s educational tool on preventing antibiotic self-medication in improving the knowledge, attitudes and practices concerning the self-medication of antibiotics of adults from two Barangays namely, Goin and Mabuhay of Liloy, Zamboanga del Norte with a total of 94 respondents. Data were gathered using a self-administered questionnaire and was given twice after the intervention. The results revealed that during the pre-intervention, the control group and experimental group were not comparable hence; the knowledge, attitude and practices were only compared before and after the intervention within groups. The control group’s knowledge and attitude mean scores did not have significant change before and after the intervention. However, the practice mean scores significantly increased on the 2nd post intervention at p-value 0.027. Meanwhile, the experimental group’s knowledge mean score increased on the 1st and 2nd post intervention, both statistically significant at p-value 0.000. The attitude mean scores of the experimental group also significantly increased in the 1st post intervention at p-value 0.003 but significantly declined on the 2nd post intervention at p-value = 0.451. The practice mean scores significantly improved both on the 1st and 2nd post intervention, at p-values 0.008 and 0.000 respectively. The results of this study showed a significant improvement on the knowledge, attitude and practices of the experimental group before and after the intervention. However, it is recommended that this study be done on 2 comparable groups to definitely test the effectiveness of Tamon’s educational tool.
