The use of brief intervention and brief therapy techniques focused on short-term, problem-specific approaches has become an increasingly important part of the continuum of care in the treatment of substance abuse problems and addictive disorders. Currently, the psychotherapy of substance abuse utilizes a wide variety of treatment modalities based on diverse theoretical perspectives, including cognitive-behavioral, strategic and interactional, humanistic and existential, psychodynamic, family systems and group therapy. This book provides an in-depth exploration of various approaches to brief therapy and their underlying theoretical constructs.
