This edition has been updated to include current research and contemporary topics. The text has been divided into four parts: Foundations, Building and Establishing Families, Maintaining Families, and Change/Turbulence/Gains/Losses. While the research methods chapter still provides an introductory examination of family science research, it now includes an expanded discussion on research design, methods, and advances in the area. A new chapter, titled "Forgiveness, Kindness, Hope, and Gratitude" has been incorporated to amplify positive family processes and highlight emerging research. This edition provides added emphasis on diverse families (e.g., race/ethnicity, family structure, LGBTQIA, ability, culture, and family formation), and each chapter includes a new "Discussions in Diversity" section related to that chapter. The authors have consciously included an epilogue as a way of reflecting on what they have learned, along with what they hope to learn in the future. Aimed at courses related to family studies and family dynamics, this text provides a comprehensive review of family processes. Whether it is used for undergraduate or graduate classes, professional growth, or personal enrichment, the text assists readers in enhancing the positive aspects of family life, avoiding undesirable aspects, and more effectively managing the challenges and obstacles families face that cannot be avoided. Thus, the text holds an appeal for people who live (or will live) in families, as well as those who want to work with families.
