This article reflects on a methodological research proposal developed from the perspective of interdisciplinary action research in the context of fear-coping interventions for older people in seven rural areas of southern Chile, following the earthquake and tsunami of February 2010. First, we used interventions based on music and art therapy to gather information on their emotional condition. We not only identified high levels of psychological stress, but also that their strengths were related to the Chilean culture and folk traditions. The creative strategies used proved to be therapeutic and healing, since participants reported they were able to express their fears, giving new meaning to their experiences in a collective context. The results highlight the importance of engaging with community members in the production of knowledge, and in defining collectively the cultural pertinence of interventions. It concludes with a discussion about the possibility of replicating this proposal in post-disaster intervention contexts.
