The traditional understanding of families, gender, and violence has historically been based on notions of functionality, normalcy, and prescribed roles. However, with the emergence of new family structures, such as women-headed families, single-parent families, same-sex families, offender families, families in foster care or institutions, adoptive families, and immigrant and refugee families affected by war or conflict, the definition of families has evolved. This evolution allows for a more progressive and nuanced understanding of familial dynamics. Similarly, perceptions of violence and conflict vary among individuals, organizations, and governments and can include domestic or partner abuse, mistreatment of children or the elderly, sexual exploitation, exposure to societal discord or war, or any form of armed aggression. Furthermore, gender is now acknowledged beyond traditional male and female categories to include LGBTQIA+ orientations. In the effort to prevent and address gender-based and family violence, it is crucial to recognize that change is complex and nonlinear, requiring sustained effort over time. The chapter suggests that a lack of understanding of power and control relations, as warned by feminist academics, can lead to victim-blaming, misinterpretation of the root causes of the issue, implementation of ineffective solutions, and potential endangerment of the victim. Additionally, while gender-based and family violence is a global issue in all its forms, effective solutions in one nation may not be suitable in another, especially considering cultural differences. Therefore, social work practice in the context of gender-based family violence requires an expansion of existing practices and definitions. Until now, interventions have been limited to legislatively structured practice settings such as shelter homes and legal implementation, which may not fully address the deep-rooted structural issues contributing to gender-based family violence, as seen in the handbook’s chapters.
