Ashford and LeCroy's groundbreaking book offers students a balanced, integrated introduction to human behavior in the social environment. Lively and comprehensive, this book succeeds by helping students connect foundation knowledge with practice concerns. Study tables and concept maps (for each discussion of behavior in the development chapters) clarify major phases of biopsychosocial development across the life span. The authors take an integrative, multidimensional approach, discussing integrative practice, theory, treatment, and services throughout. This framework gives readers a concrete tool for assessing human behavior from a perspective that truly reflects the values and knowledge base of the social work profession. The text presents solid coverage of foundation knowledge, integrates the biopsychosocial dimensions for assessing social functioning, and offers case studies to illuminate the applied aspects of HBSE content. The authors successfully combine a multidimensional approach with consistent attention to diversity, giving readers a meaningful, exciting learning experience.
