RESUMEN
BACKGROUND: Antisocial behaviour is common among patients with severe mental illness (SMI) requiring hospitalisation. AIM: To determine whether differential treatments and services are provided to patients with SMI who engage in antisocial behaviour. METHOD: A random sample of 161 inpatients with SMI were recruited from general adult wards and assessed at baseline and two years later. Information on symptoms, aggressive behaviour, substance misuse, and service use was obtained from patients and clinical files. RESULTS: Past antisocial behaviours were not associated with type or intensity of treatments and services. Severity of positive symptoms, aggressive behaviour, and illicit drug use were positively associated with the frequency of CMHT contact, but not with the type of CMHT, type of medication, or other treatments and benefits. CONCLUSIONS: While the frequency of meetings with CMHTs increased with the severity of antisocial behaviours, no specific treatments were provided to patients with SMI engaging in antisocial behaviours.
