In this framework, we present a model, called ECO2 (developed by civil society organizations in Mexico and experienced in different countries, mainly Latin Americans), for intervention on a wide range of hypercomplex phenomena called ¡°social suffering¡± that uses social networks as a useful and powerful theory and method for both diagnosis (of individuals and local communities), design and development of intervention strategies in a variety of social contexts (including those considered severe social exclusion) with objectives of prevention, harm reduction and associated risks, as well as for community-based treatment of different situations of social distress (i.e. problematic use of psychoactive substances, legal and / or illegal status, homelessness, juvenile offenders, gender violence, exploitation commercial sexual, et cetera). Within a local community, ECO2 model-based intervention seeks the articulation of a resources network, create an operational network (communitarian subjective social networks of the operators that intervene) and increase the effective complexity of people¡¯s social networks, especially those in situations of severe social exclusion. %K social network ¨C social suffering situations ¨C intervention models %U http://revista-redes.rediris.es/html-vol18/vol18_12.htm
