Summary
It is imperative that effective interventions be developed and evaluated for children with externalising disorders (e.g. oppositional disorder, attention deficit order and conduct disorder). The prevalence of these problems in the community is high, the prognosis of children is poor, and externalising problems are passed on across successive generations in the same family. Childhood externalising problems are also one of the most costly behavioural disorders for society.

The prevalence of these problems in the community is high, the prognosis of children is poor, and externalising problems are passed on across successive generations in the same family. Childhood externalising problems are also one of the most costly behavioural disorders for society. Many studies have examined the nature and course of externalising problems in older children and adolescents. However, little attention has been paid to the early onset of externalising disorders amongst preschool and early school-age children. Whilst the relationships between family risk factors (e.g. marital discord and maternal depression), parental management styles and children's behaviour problems are widely recognised, the exact nature and direction of these relationships remains largely unknown. This proposal will provide new information about the mechanism through which family risk factors such as marital discord or parental distress influence the onset and persistence of externalising problems in young children, via their effects on parents' behaviour management techniques. This information can then be used to instruct early intervention efforts for parents and families of children at risk of developing externalising behaviour problems.Read moreRead less

Summary
Borderline Personality Disorder (BPD) is a severe mental disorder involving instability of emotions, impulse control, self-concept and interpersonal relationships. BPD arises during adolescence and has a suicide rate of 10%. This study investigates the most effective form of early intervention for BPD that improves the daily lives of individuals and reduces poor outcomes, such as deliberate self-harm. The findings will inform the dissemination of early intervention for BPD in the health system.

Summary
Sleep breathing disorders (SBD) are common and affect around 10% of all children. Previous research however has shown that sleep disorders are often not recognised or considered important enough to report to general practitioners. Thus, the true incidence of sleep disorders in Australian children is not known. Nevertheless, even the mildest SBD, primary snoring, has been associated with significant deficits in daytime learning, memory, intelligence, attention and problematic behaviour.

Previous research however has shown that sleep disorders are often not recognised or considered important enough to report to general practitioners. Thus, the true incidence of sleep disorders in Australian children is not known. Nevertheless, even the mildest SBD, primary snoring, has been associated with significant deficits in daytime learning, memory, intelligence, attention and problematic behaviour. In severe cases of childhood SBD (i.e. sleep apnoea syndrome), removal of the tonsils and adenoids has been shown to improve the learning and behaviour problems. Thus there is increasing pressure on doctors to treat primary snoring in children with surgery to improve their intellectual functioning. However, recent evidence in children has shown that snoring may resolve naturally in up to 50% of cases over one to two years. In addition to the risks of surgery, the large number of children who may have a natural resolution of snoring suggestst that the pressure to treat primary snoring in may not be justified. This study will be the first to determine the prevalence of childhood snoring and associated problems in the Australian community. We also aim to discover whether snoring and the associated intellectual deficits persist over time during childhood. We will identify frequent snorers and healthy non-snorers in children aged 5-10 years old, using parental questionnaires. We will then study 75 snorers and 75 non-snorers in more detail, monitoring them with overnight sleep studies and questionnaires 2 years apart, to see if snoring, intellectual function and behavioural problems persist over time. This information will improve the health of Australian children by determining the prevalence of childhood SBD and persistence of associated deficits such as in learning, memory and behaviour.Read moreRead less

Summary
The effect of lead on children's 'intelligence' is controversial. Poorer IQ scores in children with higher exposure to lead, have been found reasonably consistently, - but there is disagreement on whether lead exposure is simply a common ASSOCIATE of poor IQ, or whether it actually CAUSES deficits. In 1994, the NHMRC prudently recommended a graded series of interventions to be implemented, depending on the proprtion of children in the community with blood lead concentrations in specific categori ....The effect of lead on children's 'intelligence' is controversial. Poorer IQ scores in children with higher exposure to lead, have been found reasonably consistently, - but there is disagreement on whether lead exposure is simply a common ASSOCIATE of poor IQ, or whether it actually CAUSES deficits. In 1994, the NHMRC prudently recommended a graded series of interventions to be implemented, depending on the proprtion of children in the community with blood lead concentrations in specific categories above 10 ug lead -100 ml of blood. The choice of this figure (10 ug-dl) was more pragmatic than scientific; there being very little data on the health effects of exposures below 10 ug-dl available at that time. A recent analysis of pooled data from past studies has now suggested there may be very large effects on child IQ at blood lead concentration BELOW 10 ug-dl. Health authorities will soon be lobbied intensely to spend vast sums on new lead abatement programs. Cities like Port Pirie and Broken Hill (where cooperative programs have achieved such significant reductions in lead exposure that a high percentage of their children now have blood lead levels below 10 ug-dl), will be forced to examine expensive options to avoid closure of the industries which provide their economic backbones, if this analysis proves to be correct. Our proposal argues that before committing to new and costly abatement programs, there is an urgent need to augment our evidence-base by conducting a new study ofchildren with lead exposures below 10 ug-dl, using more modern measures of intelligence. The study will pay closer attention to some of the socio-cultural and inherited determinants of child IQ which may have confounded the lead-IQ association in past studies, and will supplement IQ assessments (which are now considered to derive from a very old and narrow view of intelligence) with new tools for measuring 'intelligence' that may be less socio-culturally dependent.Read moreRead less
The Role Of Cannabis In An Nrg1 Animal Model Of Genetic Vulnerability To Schizophrenia

Summary
The link between psychosis and cannabis use has been discussed for decades. As the majority of users do not develop schizophrenia, it seems that other risk factors are necessary to trigger psychosis. Adolescence may be a time of particular vulnerability to the effects of cannabis use. We aim to use an animal model for schizophrenia to clarify cannabis' impact on the development of schizophrenia when interacting with the risk factors genetic vulnerability and age of onset of cannabis use.

Summary
Approximately 10% of all births are preterm and the numbers of infants surviving are increasing. We have previously found that infants born preterm have lower blood pressure over the first 6 months after term equivalent age than infants born at term. We will use new technology to examine how preterm birth affects brain oxygenation and how this is altered with gestational age, sleep states and sleeping position, to provide insights into their increased risk for SIDS.

Despite the existence of a variety of therapies including in- and outpatient programs and anti-craving medications, people continue to struggle with this problem. Increased craving for alcohol is a major factor in ability to adhere to treatment, rate of progress, and long-term maintenance of change. Whilst current medications target craving, they provide only short-term symptom relief, and not all people find them effective. Cravings are both distracting and distressing during treatment, and increased craving often predicts treatment drop-out and relapse. This project evaluates a new treatment for alcohol misuse: CARM - Craving for Alcohol: Reduction and Management. This 8-session enhanced Cognitive-Behaviour Treatment (CBT) focuses on teaching people new skills to manage and reduce cravings, and is based on a new theory of craving that has strong research support. The study compares 4 groups: CARM; a more traditional CBT treatment for alcohol problems [motivational interviewing, problem solving for high-risk situations, and relapse prevention]; plus two brief interventions [Motivational Interviewing plus Self-Monitoring, and Self-Monitoring alone] both followed by CARM after an 8 week delay. All participants are able to set their own goals of abstinence or reduced use. Expected outcomes: all participants will learn effective skills to manage their alcohol use, resulting in significant reductions in alcohol consumption and fewer problems from alcohol use; however, those receiving CARM will find it easier to manage cravings during treatment, and will make faster progress and show less treatment drop-out. It is also anticipated that participants in CARM will show better long-term maintenance of treatment gains.Read moreRead less
