Grounded in cutting-edge scientific research, this book presents innovative ways to explore and work with emotions in psychotherapy. Preeminent clinician-researcher Stefan G. Hofmann accessibly explains how emotions operate, what influences them, and how they can cause distress. He presents strategies that can significantly improve existing evidence-based treatments and promote positive affect and happiness. Clinicians are guided to help clients with any diagnosis gain emotional awareness and use emotion regulation techniques, mindfulness-based practices, and other effective strategies. “In Practice” features highlight specific clinical issues and offer illustrative case vignettes.
