This study aimed to empirically examine how national relief services influence the resolution of disaster conflicts. To achieve this, the sub-factors of national relief services were categorized into economic support, healthcare services, psychological counseling, and environmental and facility recovery, and logistic regression analysis was conducted. For the analysis, data from the fourth wave (2019) of the Disaster Victims’ Life Changes Tracking Survey collected by the National Disaster Management Research Institute were utilized. The results identified factors influencing the resolution of disaster-related conflicts, including gender, educational attainment, PTSD, life-threatening experiences, healthcare services, psychological counseling, and environmental and facility restoration. Among these, the healthcare domain within national relief services was found to have the highest odds ratio and a positive impact on resolving conflicts caused by natural disasters.
