Treating perpetrators of aggressive behavior, like verbal aggression, intimidation, and bullying behavior resulting in aggressive incidents with others, is difficult. This group is often diagnosed with personality disorders and when legal measures applied, they are more often treated in a forensic setting for their problems. This article presents the case of a 54‐year‐old man, diagnosed with Borderline personality disorder, narcissistic and antisocial traits, mild depressive symptoms, and loss and grief, who has voluntarily had treatment in a forensic outpatient center to reduce aggression and change destructive patterns in relationships. Hating, judging, and self‐defeating were the main reasons why the patient found himself ending up in the same situation repeatedly. The client received individual drama therapy sessions. The drama therapeutic approach included schema therapeutic elements, such as schema mode work with cards, as well as roleplay, imagery (with rescripting), improvisation, and psycho drama elements. As a result of drama therapy, the client reported less (active) aggression, less aggression in his relationships (partners/children/friends), but also an increased level of loneliness, and mild depressive symptoms. The client was more in touch with his vulnerability and was able to behave in a more adequate healthy way in relationships. Although self‐esteem was still building up, there was a decrease of aggression and less conflict‐seeking behavior as a result. Risk assessment tools (FARE‐2 & HONOS) and Schema therapy scales (YSQ and SMI) were used pre‐ and posttreatment confirming the improvements. This case promotes the use of dramatherapy in forensic outpatient care to be valuable in lowering risk recidivism and changing deeply rooted behavioral patterns.
