Sexual assault is a worldwide public health concern, as it occurs to people of all genders at alarming rates and results in serious physical and mental health sequelae. The reactions survivors receive from formal and informal supports can significantly influence their recovery. Given the prevalence of sexual assault, all providers need to be prepared to handle disclosures of sexual assault from clients. The aim of this book is to provide guidance on how to interact with survivors of sexual assault, which the authors define as sexual contact or penetration without the explicit consent of the victim. While the book is primarily geared toward mental health professionals, the content is also relevant for professionals who work in medical settings, educational settings, law enforcement, and victim services. The authors also highlight that there are particular populations (e.g., racial and sexual minorities) and settings (e.g., military, higher education) that require particular considerations when discussing sexual violence. Overall, professionals have an instrumental role in facilitating survivor recovery, and this book provides best practices for providing services in an affirming manner. The book begins with a review of literature focused on sexual assault and survivor disclosure. Then, recommendations are provided for conducting assessments and psychotherapy with survivors of sexual assault. Case examples are presented to help illustrate specific recommendations for working with survivors of sexual assault. Finally, particular recommendations for various specific populations are provided.
