Psychological abuse refers to the humiliation or intimidation of another person, but also used to refer to the long-term effects of emotional shock.

There are probably precise medical and legal definitions of this term.

Psychological abuse can take the form of physical intimidation, scare tactics and oppression. It is often associated with situations of power imbalance, such perhaps as the situations of abusive relationships and child abuse, however it can also take place on larger scales, such as racial oppression and bigotry. A more "mild" case might be that of workplace abuse. Workplace abuse is a large cause of workplace-related stress, which in turn is strong cause of illness, both physical and mental.

There need not be an agitator for psychological abuse to occur - one can undergo self-abuse, such as someone who is a depressive, or self-mutilation.

Any situation in which the repeated and extreme impact of a situation affects a person's emotional and rational thinking in such a way as to adversely impact their later lives could be termed as psychological abuse at some level.

Psychotherapy and psychiatric methods can help some people overcome the negative effects of abuse, given time and a healing environment.
