- Brief Summary
Considering the vulnerability of patients with schizophrenia in forensic treatment, we have designed a prospective-observational trial. The purpose of our study, notably its focus on selecting the appropriate medication, developing clinical profiles, and determining the grounds of clinical judgment, is relevant for treating patients with schizophrenia.
- Detailed Description
Patients with a schizophrenia spectrum disorder who commit violent crimes appear to have some distinguishing characteristics. The current view is that crime committed in the course of a psychiatric illness, particularly schizophrenia, is treatable and preventable. Nonetheless, treatment options for this patient group are sparse. The evidence regarding the efficacy and safety of such treatments is practically nonexistent. In practice therapeutic options are limited to medication and even here there is only one antipsychotic (clozapine) which has The current view is that crime committed during a psychiatric illness, particularly schizophrenia, is treatable and preventable. Nonetheless, treatment options for this patient group are sparse. The evidence regarding the efficacy and safety of such treatments is practically nonexistent. In practice, therapeutic options are limited to medication; even here, almost no controlled clinical trials are investigating this issue.
In clinical practice, selecting specific psychopharmacological treatments for patients with schizophrenia showing violent or aggressive behavior is particularly demanding. The lack of evidence regarding treatments for this particular group is partly attributable to their dual vulnerability and the consequent restrictions on clinical and experimental trials. Paradoxically, the efforts to ensure the safety and rights of these patients put them at a disadvantage, as they have no access to evidence-based treatment for their condition. Therefore, at best, they experience limited or slow improvement in their condition or, at worst, receive potentially ineffective or deleterious treatment.
To address the lack of evidence regarding the efficacy and safety of antipsychotic treatment options for this particular population, the investigators have designed a prospective observational study with evaluation in a mirror image design. This reduces confounders at the level of a randomized controlled trial, allowing for robust statistical analysis.

- Primary Outcome Measures
Name Time Method Psychopathology 4 weeks The Positive and Negative Syndrome Scale (PANSS) is a semi-structured interview designed to meas-ure the severity of psychopathology in patients with a psychotic disorder. The scale ranges from 30 to 210; higher scores mean greater psychopathology. Change from baseline in psychopathology on the PANSS.
- Secondary Outcome Measures
Name Time Method Aggression 12 Months The Modified Overt Aggression Scale (MOAS) is a four-part behavior rating scale used to evaluate and document the frequency and severity of aggressive episodes. It ranges 0 to 100: higher scores mean more severe aggression. Aggression and aggressive behavior as assessed by the MOAS.
Craving 4 weeks The Yale Craving Scale (YCS) is a psychometric scale for assessing smoking and drinking urges. Total scores range from 0 to 40, with higher scores indicating greater dependence. Change from baseline in craving on the YCS.
