Understanding Trauma

The Trauma Informed Practice Guide

Trauma is any experience(s) that overwhelms your capacity to cope.

Here are five general categories of trauma;

Single incident trauma is an unexpected and overwhelming event like an accident, natural disaster, a single episode of abuse or assault, sudden loss, or witnessing violence.

Complex or repetitive trauma is related to ongoing abuse, domestic violence, war, ongoing betrayal, being a first responder and often involves being trapped emotionally and/or physically.

Developmental trauma results from early, ongoing or repetitive trauma (as infants, children and youth) involving neglect, abandonment, physical abuse or assault, sexual abuse or assault, emotional abuse, witnessing violence or death, and/or coercion or betrayal. This often happens in your own family.

Intergenerational trauma describes the psychological or emotional effects that can be experienced by people who live with trauma survivors. Coping and adaptation patterns developed in response to trauma can be passed from one generation to the next.

Historical trauma is a cumulative emotional and psychological wounding over the lifespan and across generations from massive group trauma. These collective traumas are inflicted by a dominant population. Examples of historical trauma include genocide, colonialism (for example, Indian hospitals and residential schools), slavery and war. Intergenerational trauma is an aspect of historical trauma.
