Can treating psychological trauma stop the spiral of systemic violence?

Celina de Sola: Mental health care that disrupts cycles of violence · 8:48 · Video: TED · Watch at the source

In short: In regions like El Salvador, high homicide rates are fueled by a vicious cycle of violence. When individuals cannot heal from trauma, they become more prone to aggression. To break this pattern, new initiatives are training frontline workers to provide community-based mental health support where it is needed most.

Psychological trauma acts as a catalyst for further instability. Research suggests that people who have witnessed or experienced violence are more likely to engage in aggressive behavior themselves, whether within their own families or the broader community. This tendency, combined with the grief and resentment stemming from perceived injustices, creates a breeding ground for continuous outbreaks of violence.

The impact of trauma extends far beyond immediate emotional distress; it fundamentally impairs a person's ability to function and thrive. For instance, toxic stress can diminish a child's capacity to learn, even when educational resources are available. In adults, mental health conditions are linked to income penalties and difficulties in maintaining productive employment. This creates a devastating feedback loop where mental distress, low income, and diminished educational opportunities reinforce one another across generations.

Addressing this requires a shift in humanitarian strategy. While immediate needs like food and shelter are vital, they must be complemented by psychosocial support. Organizations like Glasswing International are working to disrupt these cycles by equipping government employees—such as teachers and police officers—with mental health skills. Their ambitious goal involves transforming over 2,000 frontline institutions across 25 high-risk municipalities in Central America, aiming to reach nearly 10 million people through community-based care.

The interconnectedness of mental and physical health means that untreated trauma can affect biological development even before birth. During critical stages of life, frequent toxic stress can hinder the healthy development of a child's brain and organs, making mental health care a fundamental pillar of sustainable peacebuilding.
