This book differs greatly from earlier versions because of two main changes. The first is the adoption of an intersectional approach in working with families. It underlines the importance of an intersectional approach to working with families that, in addition to culture and ethnicity, also considers socioeconomic class, gender, age, religion, immigration status, and sexual orientation as important factors. Additionally, the text expands its direct-practice view with the addition of four new chapters written by psychologists, plus a new chapter on health issues in multicultural families and access to health services. The book is updated with the latest knowledge and research, along with new and revised case vignettes demonstrating culturally competent practice. It provides a new intersectional approach to assessment and treatment and adds the perspectives of psychologists in four completely new chapters. The book includes a new chapter on the Diagnostic and Statistical Manual of Mental Disorders, fifth edition from a multicultural perspective, plus new chapters on health and access to health services and offer the most up-to-date knowledge and research.
