Title: "Mental Health Impacts of Coastal Erosion Following Hurricane Fiona in Prince Edward Island"

Climate change has intensified coastal erosion and extreme weather, increasing psychosocial vulnerability in coastal communities. Hurricane Fiona (2022) caused significant damage and disruption in Prince Edward Island (PEI), yet its mental health impacts related to coastal erosion remain underexplored. This study examines the psychosocial effects of coastal erosion following Fiona across demographic groups. A mixed-methods approach was used, including a cross-sectional survey (n = 105) and semi-structured interviews (n = 9). Quantitative analyses (Chi-square and Fisher’s exact tests) assessed associations between demographic factors and mental health outcomes, while qualitative data provided contextual insights. Psychological distress was widespread, including among those without direct physical impacts. Differences emerged across age, income, and gender, indicating varied vulnerability patterns. Key stressors included prolonged outages, infrastructure disruption, anticipated land loss, and institutional response gaps, while community cohesion acted as a protective factor. Findings highlight that mental health impacts extend beyond direct exposure and are shaped by perceived risk and environmental uncertainty. Adaptation strategies should integrate both physical and psychosocial dimensions to strengthen community resilience.
