- A multidisciplinary assertive community treatment (ACT) team, which was basically implemented according to guidelines of the Assertive Community Treatment Association and according to the Dartmouth Assertive Community Treatment Scale (DACTS). However, compared to the traditional ACT model there are two important differences: (1) While traditional ACT models have a responsibility for SPMI patients independent from the underlying diagnosis, the present model solely focus on patients with psychotic disorders; (2) The fidelity of the ACT team was further increased by composing a team of highly educated psychosis experts (i.e. consultant psychiatrists, psychiatrists, psychologists, nurses, social worker). Members of the ACT team received diagnosis-specific training in pharmacotherapy, cognitive behavioral (CBT), dynamic, and/or family psychotherapy.
