Either you read the "Unified Protocol for Transdiagnostic Treatment of Emotional disorders," by Barlow (Oxford), or "Trial-Based Cognitive Therapy: A Manual for Clinicians," written by myself (published by Routledge). TBCT is a transdiagnostic approach I developed a few years ago, and is now considered an evidence-based approach. Please, go to www.trial-basedcognitivetherapy.com. Also, you can read the attached chapters of my free book "Standard and Innovative Strategies in CBT."
