This book examines the effects of sociocultural trauma throughout the 20th century on interpersonal and family relationships in five Eastern European countries, drawing on the perspectives of mental health practitioners. Chapters employ a systemic perspective to explore the unique social, political, and cultural contexts that influence relationships in each country with a particular focus on implications for psychological and relational well-being. The volume demonstrates the importance of examining the cultural and sociocontextual nuances and complexity that may influence the impact of historical events on relationships, elucidating similarities and differences among countries in how the collective trauma has influenced them. It assists family therapists and other mental health practitioners in recognizing cultural and social factors that may influence their work with families, individuals, or couples living in these countries or who have immigrated from them. Key areas of coverage include: Descriptions of each country’s experience of sociocultural trauma and the current social-cultural-economic-political contexts. Impact of trauma on interpersonal relationships across various social locations and national and ethnic identities within the existing borders. Current challenges, recommendations for clinical practice, and future directions for research and practice. Sociocultural Trauma and Well-Being in Eastern European Family Therapy is an essential resource for clinicians, therapists, and practitioners as well as researchers, professors, and graduate students in family studies, clinical psychology, and public health as well as all interrelated disciplines.
