OBJECTIVE To assess the relationships between shy-inhibited temperament in childhood and anxiety problems in early adolescence using a prospective, longitudinal data set from a large community sample. METHOD Relationships between shyness ratings on age-appropriate temperament scales and anxiety problems were analyzed, looking both forward and backward in(More)
OBJECTIVE This study investigated the early characteristics of children who at 8 years old were hyperactive, aggressive, or both, to clarify the etiology of these disorders. METHOD Prospective data from infancy to 8 years on children who were hyperactive (N = 65), aggressive (N = 57), or both (N = 60) at 8 years were compared with those on a normal(More)
In this study of children's reading and behavior problem status from Grade 2 to Grade 4 of elementary school, we tested hypotheses concerned with the temporal and causal connections between these two closely associated disorders. Children with both, either, or neither kinds of problems were followed up over 2 years. While reading disability remained stable(More)
In this study we investigated interactions between the 5-HTTLPR genotype and environmental risk factors (G x E) on symptoms of depression in two large Australian community samples of adolescents and young adults. We postulated that a significant interaction between the 5-HTTLPR genotype and environmental risk factors of childhood adversity or stressful life(More)
BACKGROUND The aims of this study were twofold: first, to examine behavioural and academic outcomes of children with hyperactivity, using data from two longitudinal studies; and second, to examine comparable psychosocial outcomes for children with early reading difficulties. METHODS Measures of teacher-rated persistent hyperactivity, and reading ability(More)
Seven-year-old children with reading disabilities (RD-only), behaviour problems (BP-only), both conditions (RD-BP) and neither condition (Comparison) were compared on indices including temperament and behaviour, gathered in five periods between infancy and 6 years of age. The RD-BP group differed clearly from the RD-only group from infancy onwards. This(More)
OBJECTIVES Longitudinal data from infancy onwards, from the Australian Temperament Project, a prospective study of the temperament and development of a large and representative sample of Victorian children, were examined to identify predictors of psychological disorder at 11-12 years of age. METHOD Those children scoring in the at-risk range for(More)

METHOD Clinical and comparison groups of 11- to(More)
This study examined the co-occurrence of risky driving with a range of externalising and internalising problems among 1055 young Australian drivers participating in an ongoing, 23-year longitudinal study. This issue was examined by: (1) investigating the co-occurrence of risky driving and other problem outcomes at 19-20 years; (2) exploring the rate of(More)
A polymorphism in the promoter region of the serotonin transporter gene (5-HTTLPR) has been associated with anxiety-related personality traits in adults. Initial studies showed that the short allele was associated with higher neuroticism, anxiety and harm avoidance. However, most attempts to replicate these findings have been negative. Because the(More)
