Summary
This study proposes a multi-site randomised controlled trial of treatment to enhance healthy living among people with psychotic disorders, specifically targeting smoking, diet, and physical activity. These issues are highly prevalent, associated with premature death and reduced quality of life among this group. The results will better inform the treatment choices of clinicians, and will potentially improve the match between treatment and client, improving health and wellbeing of this group.

Summary
Many young people with mental health problems do not get adequate professional help because they lack relevant knowledge. This study will find out what type of knowledge is important for improving appropriate help-seeking by young Australians. Young people who were surveyed two years earlier to assess their mental health knowledge will be followed up to see whether they developed a mental health problem and what action they took to deal with it.

Summary
Measures from specialised brain scans i.e. MRI's (Magnetic Resonance Imaging) have suggested that several areas in the brain are different in those individuals who suffer from psychosis compared to those who don't. Evaluations of these brain differences have helped us better understand the nature of these illnesses.

Evaluations of these brain differences have helped us better understand the nature of these illnesses. For example, frontal lobe dysfunction has been linked with the loss of ability to plan and organize information, seen in those who have schizophrenia. These measures may also help clarify the relationship between the genetic and environmental factors contributing to the development of these disorders. One of the best ways to investigate this relationship is the use of a twin study design. The Australian study of twins with psychosis will recruit dizygotic (DZ) and monozygotic (MZ) twin pairs in which at least one twin is affected by a psychotic disorder, plus control twin pairs matched for age, sex and zygosity. Measures derived from MRI scans will be collected in an attempt to further define specific brain regions reported to be different in psychosis. In addition Diffusion Tensor Imaging (DTI) will be used to visualize white matter tracts in the brain. The twin study design will allow us to differentiate genetic and environmental factors associated with these brain measures and help evaluate the potential for these measures to genetically define sub-groups of individuals with psychotic disorders. The identification of these subgroups would facilitate the search for susceptibility genes. Additionally, this study will help clarify the possible clinical overlap between affective (i.e. bipolar affective disorder) and non-affective (i.e. schizophrenia) psychotic disorders. The information obtained from this study has the potential to greatly improve our understanding of caustive factors in psychosis, which may also lead to earlier diagnosis and treatment, thereby improving prognosis.Read moreRead less

Abnormalities in the auditory system have long been suspected to be present among people who suffer from schizophrenia and other psychotic disorders, due in part to the high prevalence of auditory hallucinations amongst these patients.

Over the last decade, a group of Australian researchers have identified an index of auditory information processing, recorded from scalp electrodes, that is abnormal in patients with schizophrenia, and their biological relatives. The present project will examine the relationship between these electrophysiological findings, and a new non-invasive technique of functional brain imaging, looking at changes in blood flow, that can identify the specific brain regions that are active during auditory information processing, and link these to the sources of the scalp recorded measures. Both of these functional measures will be examined in relation to the volumes of brain tissue, measured from magnetic resonance imaging scans using new analysis tools, that enable the identification of subtle changes in brain anatomy. By examining patients who have recently developed schizophrenia, those who have suffered from the illness for longer periods of time, and their close relatives, this study will provide the opportunity to identify biological markers of increased vulnerability for the development of schizophrenia.Read moreRead less
Labels Used By Young People To Describe Mental Disorders: Their Determinants And Impact On Stigma And Help-seeking.

Summary
When a young person first begins to experience a mental health problem, getting professional help as early as possible is recommended. However, it is unclear whether being able to label the problem correctly when they first become aware of it actually assists a young person in getting the help they need. This study will look at how over 3,000 young Australians labelled mental disorders and which labels were more likely to guide them in choosing the best kinds of professional help and treatment.

Adult anxiety and depressive disorders are common, cause significant distress to sufferers and cost to the community, and generally begin in childhood.

Prior research has shown that children who exhibit higher than average levels of anxiety in their late childhood are at risk for developing anxiety and depressive disorders as they grow older. However if at risk children can learn skills to better manage their anxiety, the chance that they will continue to experience significant anxiety problems is greatly reduced. For example, school-based skills-building programs run by specialist mental health professionals have been shown to reduce the rate of existing anxiety disorder and prevent the onset of new anxiety disorders across middle to late childhood and early adolescence. The proposed study will aim to show that a school-based program, run by school counsellors, can prevent the development of anxiety and depressive disorders in late adolescence. In other words, the aim is to demonstrate whether the benefit of the program can be achieved across the wider school-aged population when conducted wholly within the education sector. This outcome is significant, not only in its potential to reduce distress to a large number of adolescents and their families, but in reducing costs to the community in terms of reduced disability and reduced need for health care and specialist mental health treatment.Read moreRead less

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.

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

This project will conduct the first prospective analysis of acute stress disorder and chronic traumatic stress symptoms in children, develop diagnostic guidelines to identify acutely traumatized children who are at risk of PTSD, and identify biological, cognitive, and familial factors that mediate PTSD development following trauma. Two hundred children (aged 7 - 12 years) who are admitted to hospital following a traumatic injury will be assessed for acute disorder within one month of the accident. They will be also be assessed for heart rate, blood pressure, memory patterns, and family responses during the initial assesment. Parents will also be assessed for their trauma reactions. All participants will be re-assessed at 6-months posttrauma, and again at 18-months posttrauma. These findings will establish the means to identify acutely traumatized children who are at risk of PTSD and open up opportunities for early intervention and prevention of PTSD.Read moreRead less

Over the past 9 years our team has conducted a follow-up study of a large group of 111 Australian children and adolescents with autism. The young people have continued to have very high levels of emotional and behavioural disturbance and generally do not improve. Parents of children with autism are under significant amounts of stress; reporting high levels of disturbed family functioning and mental health problems. Although there is no cure, children benefit most when early help is provided (under 5 years). There are several promising interventions based on intensive behaviour and educational management, for example requiring 40 hours per week of therapist contact over 2 years. Such programs are costly and impractical as widely available treatment options. Training parents to understand and manage their child also shows promise. This study will evaluate the effectiveness of a parent skills training and education treatment program compared to supportive therapy, and to generally available community services. The therapists will follow a treatment manual that will ensure a consistent and replicable approach. The progress of the children with autism and their families will be reassessed immediately after treatment, and at 1 and 2 years post-treatment in order to ascertain immediate and long-term effects of the treatment. If treatment proves to be of use, we will have established a defined, cost efficient, practical and effective model of early treatment that can be easily taught to professionals and widely disseminated throughout early childhood services.Read moreRead less
