This study advances research on the mental health impacts of disasters by examining how a mainstay of the sociological literature, community attachment, influences negative affective states such as anxiety and fear stimulated by a technological disaster. Survey data were collected in three coastal Louisiana parishes (counties) geographically proximate to the BP oil spill of 2010 while the oil was still flowing. The data reveal that community attachment is associated with higher levels of negative affect. This finding holds for those tied to the fishing and seafood industry, those tied to the oil industry, and those having no immediate links to either industry. These results highlight that although community attachment is essential for community resilience, it can also be disruptive to individual well-being when technological disasters occur in communities dependent on renewable and natural resources.
