Perinatal, temperamental, familial, sociodemographic, and behavioral data were collected during interviews completed during pregnancy. immediately postpartum, and when the children were 6(More)
Two variants of a behavioral family intervention (BFI) program known as Triple P were compared using 87 preschoolers with co-occurring disruptive behavior and attentional/hyperactive difficulties. Families were randomly allocated to enhanced BFI (EBFI), standard BFI (SBFI), or a waitlist (WL) control group. At postintervention both BFI programs were(More)
CONTEXT Prospective cohort studies have identified an association between cannabis use and later psychosis-related outcomes, but concerns remain about unmeasured confounding variables. The use of sibling pair analysis reduces the influence of unmeasured residual confounding. OBJECTIVE To explore the association between cannabis use and psychosis-related(More)
There is an emerging interest in children and adolescents who have hallucinations and other psychotic-like experiences to enable identification of those potentially at risk for schizophrenia in adulthood. This study examines the prevalence, demographic and clinical correlates of hallucinations in the adolescent subgroup of the Australian National Survey of(More)

METHODS In a longitudinal study, 4434 families were followed-up from infancy to adolescence. RESULTS(More)
