Trauma and Abuse
Psychological AbusePsychological abuse is "interactions in which one person behaves in a violent, demeaning or invasive manner towards another person (e.g. child or partner)" - APA Dictionary of Psychology 
Psychological Trauma"Trauma can be understood as the experience of being made into an object; the victim of someone else's rage, of nature's indifference, or of one's own physical and psychological limitations. Along with the pain and fear associated with rape, combat trauma, or natural disaster come a marginally bearable sense of helplessness, a realization that one's own will and wishes become irrelevant to the course of events, leaving either a view of the self that is damaged; contaminated by humiliation, pain, and fear that the event imposed, or a fragmented sense of self." - David Spiegel. 
What is Traumatic Stress?Traumatic stress is extreme stress that overwhelms a person's ability to cope. 
Causes of Trauma
Many different types of experience can lead to psychological trauma. Some examples of experiences which cause psychological trauma include:
- accidents, e.g. motor vehicle accidents
- natural disasters, e.g. hurricanes, earthquakes
- interpersonal violence, e.g. robbery, rape and homicide and urban violence
- surgery and serious physical illness
- chronic or repetitive experiences such as child abuse and neglect
- war or living in a war zone, military combat, concentration camps
- enduring deprivation 
Different Types of Trauma - Type I and Type II
Trauma can also be classified into type forms, Type I and Type II trauma (Terr, 1991). The type of trauma a person experiences is one of a number of factors that determine the impact of the trauma, including how likely it is that the person will develop Posttraumatic Stress Disorder (PTSD) or Complex PTSD (CPTSD).
Type I Trauma
- Single-incident trauma, e.g. a sudden and unexpected trauma, a single episode or experience of trauma.
- Lower risk of Posttraumatic Stress Disorder developing when compared with Type II trauma :15
Type II trauma (Complex Trauma)
- this "usually involves a fundamental betrayal of trust in primary relationships"
- often this is inter-personal trauma, carried out by a person known to the victim.
- Affects as many as 1 in 7 to 1 in 10 children
- More often occurs in combination with other traumas or cumulatively (known as "polyvictimization")
- Involves a higher risk of Posttraumatic Stress Disorder developing. :15
PTSD Risk HierarchyDifferent traumatic experiences are associated with different chances of developing post-traumatic symptoms because the effect on a person depends on the type and severity of the trauma. :74 A theoretical hierarchy of traumatic experiences reflects this. :147
