Background: Rapid Health Impact Assessment (Rapid HIA) for Special Economic Zone (SEZ) has not been undertaken in Thailand. We aimed to develop a Rapid HIA model for policymaking by using Songkhla SEZ as a study model.
Methods: Four-stage of the research and development based on HIA process were used: 1) drafting the model using literature reviews and focus group discussions, 2) collecting additional information from 24 stakeholders, and conducting an in-depth interview with six informants, 3) verifying the model by drawing agreements on the model from 17 related agencies and experts, and 4) confirming the validity of the final model using seven experts.
