Abstract: 

Objectives: Previous literature suggests that first episode psychosis (FEP) patients with a history of offending behavior (HOB) have specific clinical needs. The aims of this study were to assess: (1) the prevalence of HOB in a representative sample of FEP; (2) the premorbid and baseline characteristics of patients with HOB, and (3) the potential differences in short-term outcome of such patients when compared to patients without HOB. Method: The Early Psychosis Prevention and Intervention Centre (EPPIC) admitted 786 FEP patients between 1998 and 2000. Data were collected from patients files using a standardized questionnaire. Data of 647 patients could be analysed. Results: HOB patients (29% of the sample) were more likely to be male with lower level of premorbid functioning and education, to be using illicit substances and to have attempted suicide. They presented with a more complex clinical picture and had poorer 18-months outcome. Most importantly, they had a significantly longer duration of untreated psychosis. Conclusions: On the basis of the high prevalence and specific features of FEP patients with HOB, our study confirms a need for additional research in this domain and for the development of specific treatment strategies. Most importantly, it suggests a need for the promotion of early detection strategies among the populations of young offenders, considering some of them may be going through the early phases of a psychotic disorder, and that reduction of treatment delay and provision of well adapted interventions may have a significant impact at numerous levels in such patients.
