Abstract
Aggression Control Therapy (ACT), a treatment programme developed in the Netherlands for violent
forensic psychiatric patients with a conduct disorder or antisocial personality disorder, was
investigated in two studies. In the first study, the personality traits and problem behaviours of these
patients and a normative Dutch population were compared, and then the traits and behaviours of
patients who completed the ACT were compared with those who dropped out. In the second study,
the ACT was evaluated by comparing pre-treatment, post-treatment, and follow-up data. Two control
conditions were added: a waiting-list period for outpatients and a control group for inpatients. The
patients who received ACT were psychologically unstable, egoistic, and prone to anger. They reported
little social anxiety when exhibiting limit-setting behaviour (e.g. giving criticism) but tended to avoid
approaching behaviour (e.g. giving a compliment). Results suggested that ACT diminished aggressive
behaviour but did not change socially competent behaviour. The limitations of the two studies are
mentioned and suggestions for further research into the effects of ACT are presented.

Introduction
Although various institutions in the Netherlands have started implementing treatment
programmes for violent forensic psychiatric patients, little is known about the character-
istics of these patients and the results of these programmes. The term violence is used here
to refer to aggressive behaviour that is intended to injure someone psychologically and
physically (Berkowitz, 1993), but especially physically (Browne & Howells, 1996). In the
Netherlands, forensic psychiatric patients are offenders for whom a judge has established,
on the basis of information provided by a psychiatrist and/or psychologist, a connection
between a deficient mental development or mental disorder' and the crime committed.
Without treatment, the risk of recidivism is high.
