The effect of behavioral modifications program for dengue fever prevention among people at Ban Kaeng subdistrict, Si Satchanalai district, Sukhothai province

Abstract

The purpose of this quasi-experimental research was to study the effect of the behavioral modification program for dengue fever prevention among people at Ban Kaeng subdistrict, Si Satchanalai district, Sukhothai province towards knowledge, attitudes, and behavior for prevention of dengue fever, and Aedes larval indices (house index: HI). Samples were people who were selected with simple random sampling that representing 86 households, one person from one household, totally 86 people. They were divided into 2 groups: the experimental group consisted of 43 people from 43 households in Ban Kaeng Tai, Ban Kaeng subdistrict, Si Satchanalai district, Sukhothai province and the comparison group consisted of 43 people from 43 households in Ban Pong, Sarachit subdistrict, Si Satchanalai district, Sukhothai province. Research tools consisted of the behavioral modification program, assessment form of knowledge, attitude, and behavior to prevent dengue fever. Data were analyzed with statistics including frequency, percentage, mean, standard deviation, independent t-test and paired t- test. Statistical significance level was set at 0.05.

The results found that after performance of the behavioral modification program for dengue fever prevention, the experimental group had mean scores of dengue fever knowledge (12.86, 9.18, p<0.001), dengue fever attitude (43.18, 36.65, p<0.001), and dengue fever behavior prevention (17.18, 13.95, p<0.001) higher than before performance of the program statistical significance, and also the Aedes larval indices (house index: HI) was lower than before the program statistical significance (1.35, 9.50, p<0.001). Moreover, the group that received the behavioral modification program for dengue fever prevention, the mean scores for dengue fever knowledge (12.86, 9.02, p<0.001), dengue fever attitude (43.18, 36.06, p<0 . 0 0 1 ) , and dengue fever behavior prevention (1 7 . 1 8 , 1 3 . 3 0 , p<0 . 0 0 1 ) were higher than the comparison group statistically significant, and also the Aedes larval indices (HI) (1.35, 9.00, p<0.001) was statistical significantly lower than the comparison group.

In conclusion, from the results of this study, the behavioral modification program for dengue fever prevention should be implemented to improve the behavior of people for dengue fever prevention, and reduce Aedes larval cover all areas at risk of dengue fever for prevent and control of dengue fever in the community.
