This groundbreaking book on the gender-inclusive treatment of intimate partner abuse has been fully updated to reflect new and refined evidence-based approaches that have evolved since the first edition was published nearly ten years ago. It describes new treatment protocols that are strongly supported by current research that enables mental health practitioners to engage in a more nuanced-and gender inclusive conceptualisation and treatment of intimate partner abuse in its many permutations. The book eschews the field's previous reliance on traditional domestic violence and treatment protocols to offer new paradigms that reflect the trend toward a more balanced, evidence-based and less heteronormative conceptualisation of partner abuse. It presents the latest findings from the third installment of the Partner Abuse State of Knowledge Project. Included are new examples of evidence-based programs currently in existence and those that are in formative stages, fully updated exercises and handouts, new risk assessment instruments, and new definitions of evidence-based treatment. Of special note are several new appendices that include updated assessment forms, a victim safety plan, client workbook guidelines and exercises, resources and programs for court-ordered clients, and exercises for high conflict family violence parent groups. In addition, a new assessment protocol will be available as a free download.
