Risk factor findings suggest importance of relational issues in treatment of women • Partner’s drinking • Marital/relationship distress • Intimate partner violence • Sexual adjustment/satisfaction
Central importance of childhood sexual victimization suggests attention to . . . • Treatment of major sequelae of CSA (including shame/self-blame, anxiety, depression, impaired relationships, avoidant coping strategies) • Early intervention with CSA victims • Community-based prevention of CSA and other child maltreatment
