The purpose of this multiple case study was to gather information about female aggression in situationally violent relationship. The interviews and surveys of four African-American couples were coded and analyzed to gather information about the impact of female aggression on the relationship, the contextual factors surrounding female aggression, and the motivations for female aggression. The results indicated that female aggression impacts the couple relationship in several ways. First, female aggression is typically minimized by both partners. Another impact on the relationship is that it leads to further escalation of aggression, as well as leading the couple to question their commitment to each other. Female aggression also appeared to become part of the couples struggle for power. The study also identified substance abuse and a family history of abuse as two of the contextual factors present with female aggression. The motives for female aggression that were identified included frustration, wanting control over the relationship, abandonment and retribution. One couple identified self-defense as a motivation for female aggression. Implications for future research and for clinical practice are offered. / Master of Science
