Spanish Ministry of Health Launches Three-Year Study on Mental Health Impact of DANA Flooding in Valencia

The Spanish Ministry of Health has initiated a pioneering three-year study to evaluate the mental health effects of the severe DANA flooding that struck the Valencian Community in October 2024. This extreme weather event impacted 74 municipalities and affected around one million residents, causing significant material damage and loss of life.

The prospective cohort study aims to assess the prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) among those exposed to the disaster. Researchers will follow at least 8,153 adults and 2,718 minors selected from 23,318 households in affected areas. Initial data collection will begin one year after the flood, with two subsequent follow-ups planned at two and three years.

Utilizing a stratified random sampling method, participants—from a reference population of over 600,000 individuals—will provide detailed information about their health status, social support, and disaster experiences through questionnaires conducted in person or by phone. The study intends to identify how exposure levels and various sociodemographic and personal factors contribute to psychological distress.

This effort, inspired by international flood health studies, seeks to generate local evidence to better inform health services and emergency response plans amid the growing challenges posed by climate change. The Ministry underscores its commitment to enhancing the capacity to manage mental health consequences following extreme weather events, improving preparedness for future emergencies.
