Domestic violence (also named domestic abuse or family violence) is a pattern of behavior which involves violence or other abuse by one person against another in a domestic setting, such as in marriage or cohabitation. It may be termed intimate partner violence when committed by a spouse or partner in an intimate relationship against the other spouse or partner, and can take place in heterosexual or same-sex relationships, or between former spouses or partners. Domestic violence can also involve violence against children, parents, or the elderly, and may be done for self-defense. It takes a number of forms, including physical, verbal, emotional, economic, religious, reproductive, and sexual abuse, which can range from subtle, coercive forms to marital rape and to violent physical abuse such as choking, beating, female genital mutilation and acid throwing that results in disfigurement or death. Domestic murders include stoning, bride burning, honor killings, and dowry deaths.
Studies have found high incidence of psychopathology among domestic abusers. For instance, some research suggests that about 80% of both court-referred and self-referred men in these domestic violence studies exhibited diagnosable psychopathology, typically personality disorders. "The estimate of personality disorders in the general population would be more in the 15–20% range [...] As violence becomes more severe and chronic in the relationship, the likelihood of psychopathology in these men approaches 100%."
Dutton has suggested a psychological profile of men who abuse their wives, arguing that they have borderline personalities that are developed early in life. However, these psychological theories are disputed: Gelles suggests that psychological theories are limited, and points out that other researchers have found that only 10% (or less) fit this psychological profile. He argues that social factors are important, while personality traits, mental illness, or psychopathy are lesser factors.
An evolutionary psychological explanation of domestic violence is that it represents male attempts to control female reproduction and ensure sexual exclusivity.[288] Violence related to extramarital relations is seen as justified in certain parts of the world. For instance, a survey in Diyarbakir, Turkey, found that, when asked the appropriate punishment for a woman who has committed adultery, 37% of respondents said she should be killed, while 21% said her nose or ears should be cut off. Similar feelings may at times be generated in a situations where one partner is more financially successful.
