Non-substance-related addiction disorders have increasingly come into focus in scientific research in recent years. In 2013, the so-called behavioral addictions were also included in the DSM-5. This book addresses three specific behavioral addictions: pathological buying, pathological gambling, and internet addiction. There appears to be a particularly high risk of these non-substance-related dependencies in the population. The volume describes the characteristics of the three behavioral addictions, provides information on the course of the disorders, offers differential diagnostic insights, and gives an overview of diagnostic procedures and documentation aids. Disorder-specific cognitive-behavioral therapy approaches that have proven effective in treating the three disorders are presented in a practical manner. This includes building motivation for change, preparing behavioral analyses, developing an individual model of onset, and conducting exposure therapy.
