This guide is designed to assist therapists in training—mental health counselors, psychologists, social workers, school counselors, substance abuse counselors, psychotherapists, and peer helpers—in the process of finding a theoretical orientation congruent with their own personal values. In it, readers get a look at the theory and practices involved in the process; a concise, helpful reminder/overview of the major theories of counseling; and specific learning activities, reflection questions, and case examples interspersed throughout. Unique to this book are the authors’ Intentional Theory Selection (ITS) model, a contemporary model for selecting a theoretical orientation congruent with one’s personal values, and the Selective Theory Sorter-Revised (STS-R), a survey for discovering which research theories a counselor might endorse. Updated throughout, the Third Edition focuses on assisting clinicians further in finding their theoretical orientation in a diverse society while enjoying the self-exploration process. The authors have presented the ITS model and the STS-R at many professional conferences, incorporating the feedback into the new edition.
