This study describes a model to intervene in communities affected by the political violence impacting the Ayacucho region of Peru since 1980s. Many community members still experience psychosocial consequences to this day due primarily to grief. Thirty-eight professionals from different sectors in the area received specialized training and implemented five community projects that were accompanied and monitored in the field by a team of community psychologists. This article is grounded on the principles of participation, building community capacity, and community strengthening. We present the analysis of five community action plans implemented over a period of 14 months. The results show a process of internal strengthening of community services and the identification of new social and community resources among the people involved in the action plans. The implications of capacity building for improving community mental health are discussed.
