Therefore, the bidirectional of sexual Intimate Partner Violence in our study may occur for reasons other than those explaining the bidirectionality of physical or psychological Intimate Partner Violence (Hines, 2007). For example, whereas women’s psychological and physical Intimate Partner Violence perpetration have often been explained as self-defense (Stuart et al., 2006; Swan et al., 2012), women’s use of sexual Intimate Partner Violence has been explained as the expression of adversarial sexual beliefs (Hines, 2007).
