219ASSESSING DENGUE PREVENTION BEHAVIOR USING A VALID AND RELIABLE INSTRUMENTIndia has high rates of dengue, a vector-borne disease. As long as people continue to allow mosquitoes to breed in their housing compound, government efforts will not be sufficient to prevent the disease. Dengue prevention depends heavily on individual or community behaviour. The associated factors that contribute to dengue prevention behaviour, however, cannot be measured by a standard instrument. A newly developed instrument for measuring dengue prevention behaviours was validated and compared to a previously tested instrument. This study involved 300 respondents as a preliminary study to a larger study. A latent variable exploration was carried out with exploratory factor analysis (EFA). Using the EFA, 10 factors were identified (knowledge of dengue, behaviour toward dengue prevention, fear and awareness of dengue, A study determined that 70.2% of the total variance was attributed to factors such as motivation to take preventive measures, medical practices associated with dengue fever, cooperation in dengue prevention, perceptions of susceptibility, perceptions of severity, perceived benefits from taking steps to prevent dengue, and perceived barriers to taking steps to prevent dengue.). Dengue-prevention behaviours can be measured with the questionnaire in a valid and reliable manner25.purnas@gmail.comResearch1312023Dengue, Prevention, Awareness of dengueDr. Purna Chandra Rao J,Dr. Harish KSenior Resident in General Medicine, NRI Medical College, Chinakakani, Andhra Pradesh, India,Associate Professor in General medicine department, NRI Medical College, Chinakakani, Andhra Pradesh, India.
