This study explores the relationship between terrorism risk and international vacation tourism decisions. The research examines eight independent variables—international travel experience, risk perception level, international travel attitude, age, gender, education, income, and presence of children in the household—and three key stages of the decision-making process: the general decision to travel internationally versus domestically, the extent of information search, and concern for safety in evaluating destination alternatives. A mail survey of international tourists achieved a 48% response rate, with non-response bias tested through telephone interviews. Data were analyzed using multiple and simple regression. The results indicate that international attitude, risk perception level, and income directly influence international vacation destination choice, while tourist experience and education have indirect influences. The study highlights the significant impact of terrorism risk on tourists' decision-making processes and provides insights for the tourism industry to better understand and mitigate these risks.This study explores the relationship between terrorism risk and international vacation tourism decisions.
