The aim of this study was to study the relationships between economic
status, knowledge, attitude and practice regarding dengue fever (DF), attitude
towards vaccination against dengue virus infection, willingness to participate in
a study on dengue, and acceptance of a dengue vaccine. Information on variables
of interest was collected in questionnaire-assisted interviews during a communitybased
cross-sectional survey conducted in Aceh, Indonesia. A proposed relationship
model was tested using Confirmatory Factor Analysis (CFA), and an Exploratory
Factor Analysis (EFA) was used to reconstruct an alternative relationship
model among variables. Our proposed relationship model differed from the result
of the EFA. The CFA indicated that knowledge and attitudes towards DF had the
strongest relationship. We also found several direct relationships between sets of
variables: a) economic status and knowledge on DF, b) economic status and practices
regarding DF, c) knowledge and practices regarding DF, d) attitudes towards
DF and dengue vaccine acceptance, as well as e) attitudes towards vaccination and
dengue vaccine acceptance. There was no relationship between economic status
and dengue vaccine acceptance. In conclusion, our model suggested that the most
suitable factor to be targeted for improving dengue prevention was knowledge
about DF. In addition, improving attitudes towards vaccination seemed to be the
most appropriate effort to increase public acceptance of a dengue vaccine.
