Adaptation of PhotoVoice methodology to promote policy dialog among street-based drug users in Santo Domingo, Dominican Republic.

Background Like other epidemics, the current heroin epidemic in Santo Domingo, Dominican Republic is a largely invisible and devastating social problem linked to numerous structural and social determinants of health.Methods In this article, we connect a community-based participatory research methodology - "PhotoVoice" - with the theoretical orientation of critical medical anthropology to identify local interpretations of complex social and structural factors that are most salient to the well-being of local Dominican populations affected by drug addiction.Results Specifically, we describe Proyecto Lentes (Lens Project), a PhotoVoice initiative launched in 2014, which brought together active drug users to visually unveil and critically analyze the micro- and macro-factors shaping the marginalized and stigmatized drug addiction epidemic in Santo Domingo.Conclusions While the synthesis of PhotoVoice and critical medical anthropology provides a powerful political analysis tool, this fusion is particularly apt in its ability to capture the "invisible voices" of marginalized communities, potentially contributing to future policy reform and social empowerment.
