OBJECTIVE To identify the treated incidence of psychosis in catchment of the Early Psychosis Prevention and Intervention Centre (EPPIC), Melbourne, Australia. METHOD Cases were aged 15-29 years with a first episode of a psychotic disorder accepted into EPPIC between 1997 and 2000. Age- and sex-specific incidence rates per 10,000 person-years were(More)
OBJECTIVE An association between childhood behavioral disturbance and adulthood schizophrenia has been seen previously in retrospective or follow-back studies and in prospective studies. The authors examined the relationship between childhood behavioral problems and adulthood schizophrenia-related psychoses. Because a high rate of childhood behavioral(More)
BACKGROUND Around 20% of patients who suffer from psychosis will experience a single psychotic episode (SPE), but relatively little is known about the characteristics and predictors for this group of patients. This study sought to: 1) characterise the subgroup of first-episode psychosis (FEP) patients who experienced a SPE over a 7.5-year follow-up; and 2)(More)
The positive (perceptual-cognitive) and negative (social-interpersonal) dimensions of schizotypal personality traits were examined in biological relatives of individuals with Axis I disorder. The subjects were young adult offspring from three contrasting parental groups, including schizophrenic disorder, affective disorder, and normal controls. Cognitive(More)
Cognitive impairment is an important clinical feature in many individuals with schizophrenia. Factors associated with cognitive deficit are not well established. Duration of untreated psychosis (DUP) has recently gained interest as a prognostic factor in schizophrenia. This study reports on the association between DUP and cognitive function. Subjects(More)
BACKGROUND In recent years there has been increasing interest in functional recovery in the early phase of schizophrenia. Concurrently, new remission criteria have been proposed and several studies have examined their clinical relevance for prediction of functional outcome in first-episode psychosis (FEP). However, the longitudinal interrelationship between(More)
OBJECTIVE We examined if age of onset of psychiatric symptoms and/or sex predict conversion to non-affective or affective psychosis in individuals considered to be at ultra-high risk for schizophrenia. METHOD Participants (n=86) were offered treatment and monthly follow-up until transition to psychosis, or for 12 months if they did not meet exit criteria(More)
OBJECTIVE We aimed to replicate a recent finding of high prevalence of trauma history in patients at 'ultra-high risk' (UHR) of psychotic disorder and to investigate whether trauma predicts conversion to psychosis in this population. METHOD A consecutive sample of UHR patients was assessed. History of trauma was accessed with the General Trauma(More)
AIM An estimated 75% of mental disorders begin before the age of 24 and approximately 25% of 13-24-year-olds are affected by mental disorders at any one time. To better understand and ideally prevent the onset of post-pubertal mental disorders, a clinical staging model has been proposed that provides a longitudinal perspective of illness development.
