This action research aimed to develop the model of dengue hemorrhagic fever (DHF) prevention and control in BanSaiKluay Village, Phattalung, Thailand. The sample were 212 of household representatives (162), teachers (21), village health volunteers (12), Buddhist monks (7), community leaders (6), public health officers (2), and local government organization officers (2). Two phases of model development were applied. The result emerged the BanSaikluay ACER model for DHF prevention and control consisted of 4 stages. Assessment stage (A) consisted of 1) identifying the involved persons, 2) collecting mosquito larva index, 3) assessing DHF risk area, 4) assessing the policies and supports by administrators of involved organizations, and 5) assessing the knowledge, attitude, practice, participation and learning community of involved persons. Co-creating stage (C), the cooperation of involved persons, consisted of 1) installing the Mosq App. on involved person smartphones, 2) planning for the improvement of knowledge, attitude, practice, participation and community learning of an individual involved person and 3) improving as the plan. The evaluation stage (E) consisted of 1) comparing the knowledge, attitude, practice, participation and learning community of involved persons before and after the co-creating stage, 2) comparing mosquito index before and after the co-creating stage and 3) collecting the number of DHF patients. Returning stage (R) was conducted after ACE stages were accomplished and ready to return the model, Mosq.App. and important data to BanSaiKluay village to continue implementing the activities in the model. The ACER model was an original model which requires the continuous refinement for more effectiveness. The model could be generalized for DHF prevention and control in other communities, especially in tropical area.
