What is Trauma?
A trauma is a deeply distressing and disturbing experience. They are often defined as “experiences which are life threatening or pose a significant threat to a person’s physical or psychological wellbeing”.
Examples of potentially traumatic events include:
- Sexual and/or physical abuse.
- Sudden unexpected or violent death of someone close (e.g. accident, suicide).
- Natural disaster (e.g. earthquake, flood, bushfire).
- Involvement in a serious car accident.
- War or political violence (e.g. terrorism, becoming a refugee, civil war).
A person’s available support following a trauma, past life experiences, physical health, mental health and coping skills can all influence how they respond to such an event.
