Everyone has unpleasant thoughts and difficult emotions, and that's normal. But sometimes negative thoughts are repeated and become obsessive over time. Such a problem may be evidence of obsessive-compulsive disorder (OCD) or its prerequisite. Intrusive thoughts and a constant stream of difficult feelings greatly affect the quality of life and prevent you from enjoying being in the present. The workbook's authors, John Hershfield and Blaise Aguirre, draw on their extensive experience in psychiatry and psychotherapy to teach you how to effectively deal with obsessions (that is, recurring unwanted thoughts) and compulsions (that is, rituals and compulsions) and break the vicious cycle. The authors suggest cognitive behavioral therapy (CBT) and dialectical behavior therapy (DBT) as effective methods. John Hershfield and Blaise Aguirre use exposure in their practice: they advise clients to face their own fears and not succumb to unhealthy repetitive scenarios. The theory in the workbook will help you dot all the i's, and the practical part will help you in consolidating the material and putting useful skills into practice.
