Dengue Chit-Chat (DCC) is a text-messaging based intervention that can be used to improve ME. The aim of this study was to analyse the effect of DCC on the mother’s ME behavior in Bali. Methods/Statistical analysis: This study was a quasi-experimental with pre-test and post-test with control group design and cluster sampling technique. Sixty-seven participants were divided into experimental and control groups. The experimental group was given a three weeks message program that was delivered four times a week. Findings: Statistical analyses showed no significant differences in knowledge (p=0.064) and container index score (p=0.051), but showed significant differences in attitude (p<0.001) and practice (p<0.001) before and after the intervention. Improvements/Applications: Based on these results, we conclude that DCC can be used to increase attitude and practice of ME. However, study with a longer intervention duration may be needed to explore the behavioral effect of text-messaging intervention on ME.
