In this chapter, we review the current status of the behaviorally oriented group therapy model for sex offenders (primarily developed from work with prison populations), discuss the psychodynamic model, and introduce the use of a hybrid psychodynamic model of group therapy emphasizing an integration of cognitive-behavioral therapy with a broad-based psychodynamic theory involving attachment theory, self psychology, and object-relations theory, and informed by psychoanalytic theory. To illustrate the approach to treatment advocated, clinical vignettes of typical cases are presented and then a clinical example from one session in a long-term therapy group is presented.
