Psychodynamic art psychotherapy for the treatment of aggression in an individual with antisocial personality disorder in a secure forensic hospital: A single-case design study.

The aim of this single-case study was to investigate the responses to psychodynamic art psychotherapy from a man who had a diagnosis of antisocial personality disorder and ongoing aggressive behavior in a secure care setting. The intervention was 19 sessions of psychodynamic art psychotherapy lasting up to 1 hr per week. This study uses a single-case design with pretreatment, treatment, and posttreatment follow-up assessment of symptoms using multiple methods reported by the therapist, other staff members, and the patient. Treatment progress was assessed by (a) repeated self-report symptom measurements, (b) continuous assessment of observed aggressive behavior and risk incident reports in the hospital, (c) pre-post treatment assessment of relationship patterns and interpersonal schemas, and (d) interviews with the patient and his nurse at 9-month follow-up, retrospectively assessing the change. The patient showed a clinically significant reduction pre-post and pre-follow-up in symptoms. Behavioral observations indicated a reduction of overt aggression and risk-related incidents. Comparison of the Core Conflictual Relationship Theme pre-post treatment indicated positive changes in interpersonal schemas. This illustrative systematic single-case study highlights the potential for investigation of a novel psychotherapeutic approach that has in turn led to further developments in clinical research.
