The integrative framework in this book synthesizes common factors research into a comprehensive set of guidelines for improving clinical practice and training. The five common factors reviewed in this book are the therapeutic relationship, motivation, insight, self-efficacy, and corrective experiencing. Each serves as a guiding heuristic for psychotherapists of any background. Beginning with a wide-angle view of past theoretical and empirical work, the contextual model, and other integrative perspectives and approaches, the book establishes a foundation for a more well-defined common factors model of treatment. Each factor is then broken down into a set of core principles and intervention concepts and example techniques, such as motivational interviewing skills, a framework for confronting distress and moving towards change, adopting a multicultural orientation, and empowering clients. Deliberate practice methods are provided so that clinicians can rehearse common factor approaches and integrate them into their own work.
