The fourth edition of Theoretical Models of Counseling and Psychotherapy provides a comprehensive overview of a variety of major counseling theories and focuses on the integration of different theoretical models. With new information on multiculturalism and diversity, the book offers a detailed description of the philosophical basis for each theory as well as historical context and biographical information on each theory’s founder. Chapters include new case excerpts and clinical examples, and each chapter follows a consistent structure in its exploration of each theory’s features, including its approach to and ideas on personality development, human nature, the role of environment, the change process in therapy, and contributions to the mental health field. Theory-specific information on diagnosis, psychopharmacology, spirituality, and gender issues is also discussed, and there is an added emphasis on diversity and social justice issues. The book is accompanied by instructor and student resources where professors and students will find exercises and course material that will further deepen their understanding of counseling theory and allow them to easily bridge classroom study to future practice.
