One recent advance in the field of psychodynamic therapy is the development of internet-based models in the form of guided self-help. Typically, these treatments are in the form of self-help material that is provided to a client over the internet with additional therapist contact by e-mail. This chapter aims to introduce two distinct models of internet-based psychodynamic therapy in detail, give an overview of the current evidence base, and provide clinical illustrations of the process of working with this form of psychodynamic therapy.
