 Other studies that decontextualized partner violence included labeling aggregate findings of motivations for violence that included the desire to coerce or control the partner or being angry with the partner as "striking back" when such questions revealed that women scored equal to or higher than men in desires to use violence out of simple anger or to coerce and control the partner.This, however, is contradicted by other reviews which found women's primary motivation were triggered by anger or self-defense while men's motivation was more about control.Some studies have also postulated that when other factors such as allowing both or neither gender to claim self-defense, or simply including male victims and female perpetrators in the sample, the results were at or near parity for perpetrators and victims, with the results near parity sometimes favoring females and sometimes favoring males.
