Internet-delivered psychodynamic treatments (IPDT) have a shorter history and smaller research base than those based on CBT, but the number of studies is rapidly growing. This chapter introduces the theoretical background and main principles of those IPDT treatments researched as of yet. Furthermore, it presents an overview of the research base for IPDT for different psychiatric disorders, where IPDT shows promising results for adult depression, adolescent depression, and several anxiety disorders in adulthood, as well as an adjunct treatment for inpatients with mixed disorders. Lastly, the chapter provides an illustrative case example of a treatment process in IPDT for adolescent depression.
