Transdiagnostic Group Therapy Training and Implementation provides clinicians with a user-friendly roadmap for delivering a brief, transdiagnostic group therapy that can be used for patients suffering from stress, depression, anxiety, and a range of other related mental health problems. This is supplemented by over an hour of training videos hosted on the book's companion website, visually demonstrating how to effectively implement the therapy. The book introduces the empirical research that has led to a greater emphasis on transdiagnostic treatment approaches, and details how to implement each phase of the therapy, supported by clinical examples to make practical application easier.
