The most common and extreme suffering humankind has ever experienced comes from interpersonal and collective intentional violence. In dealing with traumatic outcomes psychology must overcome the mutually constitutive interaction between the (dis)order of a given macro or microsocial context and the mental health of the persons living in it. Social psychologist Ignacio Martín-Baró addressed in a preferential way the study of civil war in El Salvador in terms of intergroup hostility and polarization. He also approached the aftereffects of war by means of a theoretical core assumption: that traumatic experience rooted in collective violence (a human-made stressor) should be understood bearing in mind its social roots (pretraumatic situation), its personal and collective harm (collective injury), and the destruction of the social fabric. These are the arguments for his conceptualization of psychosocial trauma. Twenty-six years after the violent murder of Martín-Baró, along with 5 Jesuit priests, a housekeeper, and his teenage daughter, the current authors have adopted his general framework. Based on new theoretical insights and supporting data, the authors propose an expanded 4-dimension theoretical argument on psychosocial trauma: (a) pretrauma conditions based on social distress, (b) shared network of fear leading to breakdown of core social assumptions, (c) the outgroup as a target of negative emotions, and (d) destruction of family ties and community networks.
