In this revision of their ground-breaking book, the authors offer an even more balanced, integrated, and applied text. In addition, the book's multidimensional framework, integration of the biopsychosocial dimensions for assessing social functioning, attention to foundation knowledge and diversity, and use of case studies to illuminate the applied aspects of HBSE content all combine to give readers an experience that is meaningful and exciting. Using a unique, multidimensional framework for assessing behavior, the authors look at biopsychosocial development across the life span. Essentially, the framework provides a concrete tool for the reader to assess human behavior from a perspective that truly reflects the values and knowledge base of the social work profession. Lively and comprehensive, this book succeeds by helping students connect foundation knowledge with practice concerns.
