Behavioral Change Program for Prevention and Control of Dengue Fever at Hong Charoen Subdistrict, Tha Sae District, Chumphon Province

Abstract

This study is quasi-experimental research that aims to study the effectiveness of behavior modification programs in the prevention and control of dengue fever. Hong Charoen Subdistrict, Tha Sae District, Chumphon Province. The sample group consisted of 88 people, divided into an experimental group of 44 people and a control group of 44 people, using multi-stage random sampling. The research period was 12 weeks. Data was collected using a questionnaire on knowledge about dengue fever. Perception of risk opportunities perception of violence perceived benefits Obstacle perception Behaviors for prevention and control of dengue fever and the mosquito larvae index value Data were analyzed using descriptive statistics including number, percentage, mean, and standard deviation. Inferential statistics were analyzed using an independent t-test at the statistical significance level of 0.05.

The research results found that After receiving the behavior modification program for prevention and control of dengue fever, knowledge (_diff.=3.68, 95% CI = 2.84 to 4.51), perception of severity (_diff.=1.04, 95% CI = 0.08 to 2.00) Perceived barriers (_diff.= 0.93, 95% CI = -0.04 to 1.91,P-value = 0.062) Dengue fever prevention and control behavior (_diff.= 2.50, 95% CI = 0.81 to 4.81,P-value = 0.004)  The two groups were significantly different at the 0.05 level. The Aedes larvae index value, week 4, week 8, and week 12 found that the experimental group had a mosquito larvae index value HI (House Index) less than the control group, with differences of 6.20 percent, 6.45, and 5.64 percent, respectively, and 10 percent lower.
