Large carnivores are prioritized in conservation, but their co-occurrence with humans and domestic animals can generate conflict. Interventions preventing carnivore attacks are central to carnivore conservation, but are only effective if implemented. This study investigates drivers of the intention to use interventions among animal owners in Sweden based on the Theory of Planned Behavior, extended with the emotion construct Worry. Additionally, the study includes an explorative analysis investigating the processes behind this worry based on the Appraisal Theory of Emotion. In a survey comprising 1,163 animal owners, the subjective norm is identified as an important driver in the regression model of intended intervention use. Adding Worry to the model increased the amount of explained variance. Worry, in turn was mainly explained by experienced vulnerability among animal owners. This study illustrates how emotion theory can extend TPB to enhance understanding of human behavior, important for future coexistence between humans and wildlife.
