This project aims to investigate the nature of this anxiety and the nature of the stimuli that produce it. The outcomes should be a better understanding of the neural basis and pharmacology of anxiety states and the identification of novel chemicals that have powerful rodent repellent properties. Such chemicals may be of great use in domestic and agricultural contexts where rodents are pests.Read moreRead less

Summary
Treatment-induced compulsive behaviours: Ethical and policy implications. Compulsive behaviours represent one of the largest preventable burdens in society. Some medications, such as those used to treat Parkinson's disease, can produce severe compulsions in certain individuals, which are akin to addiction. This project will explore: neurocognitive changes caused by these medications; the impact that drug-induced compulsive behaviours have on affected individuals, their sense of agency, identity ....Treatment-induced compulsive behaviours: Ethical and policy implications. Compulsive behaviours represent one of the largest preventable burdens in society. Some medications, such as those used to treat Parkinson's disease, can produce severe compulsions in certain individuals, which are akin to addiction. This project will explore: neurocognitive changes caused by these medications; the impact that drug-induced compulsive behaviours have on affected individuals, their sense of agency, identity and moral responsibility; and the ethical, legal and policy consequences of drug-induced behaviour. This project will help us to understand the neuropsychology of compulsive behaviour and reduce its occurrence. It will also enable society to meet the ethical and policy challenges raised by neuroscience research on compulsive behaviour.Read moreRead less
Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as pred ....Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as predator cues, enhance avoidance behaviour. This project will uncover the neural circuitry and endocrine mechanisms through which hunger influences hypothalamic threat-detecting circuits that suppress food intake. These studies provide a new hypothalamic model to understand risk/reward decision in the brain.Read moreRead less
Prospective predictors of body image attitudes and dieting beliefs during first years of school: Providing guidance for prevention. Although it is recognised that body dissatisfaction is a risk factor for the development of a wide range of mental health problems, little is known about its early development. There is a distinct increase in body dissatisfaction and dieting awareness during early school years. However, there has not been an exploration of a wide range of family, media, peer and sch ....Prospective predictors of body image attitudes and dieting beliefs during first years of school: Providing guidance for prevention. Although it is recognised that body dissatisfaction is a risk factor for the development of a wide range of mental health problems, little is known about its early development. There is a distinct increase in body dissatisfaction and dieting awareness during early school years. However, there has not been an exploration of a wide range of family, media, peer and school adaptation variables as predictors of body image and weight change behaviours in both girls and boys. This project will examine prospective predictors of body image and related variables in five to seven years old children. Findings will inform development of prevention interventions to assist parents and schools provide a positive body image and eating environment for Australian children.Read moreRead less
Addressing risk factors of overweight and obesity among adolescents in out-of-home care: The Healthy Eating and Active Living (HEAL) study. The health risk of overweight and obesity when adolescents are placed in out-of-home care has been largely ignored. This project will be the first to evaluate a healthy eating and physical activity obesity prevention/intervention program designed specifically for vulnerable and disadvantaged adolescents living in out-of-home residential care.
Enhancing psychosocial adaptation after temporal lobectomy surgery for control of epilepsy seizures. Preliminary data from individuals who have experienced temporal lobectomy surgery for control of epilepsy seizures suggests that (a) psychosocial adjustment problems may occur even when the neurological outcome is excellent, and (b) satisfaction with surgery/ post-surgery adjustment relates to perceived control over pre-surgery decision- making. The aim of this study is to improve pre-surgery pro ....Enhancing psychosocial adaptation after temporal lobectomy surgery for control of epilepsy seizures. Preliminary data from individuals who have experienced temporal lobectomy surgery for control of epilepsy seizures suggests that (a) psychosocial adjustment problems may occur even when the neurological outcome is excellent, and (b) satisfaction with surgery/ post-surgery adjustment relates to perceived control over pre-surgery decision- making. The aim of this study is to improve pre-surgery procedure and post-surgery support by investigating psychosocial outcomes of epilepsy surgery, and relating these to perceived and actual pre-surgery preparation, including education, counselling and social support. The results of the study will inform development of resource material for the medical profession and potential surgery clients, as well as contributing to improved understanding of the relationship between pre-surgery procedures and psychosocial outcomes.Read moreRead less
Promoting fit bodies, healthy eating and physical activity among Indigenous Australian men. Overall, the physical and emotional health of our Indigenous people is the worst in Australia. A major contributing factor is the significant lifestyle changes that have eroded traditional ways of life. These include the adoption of diets that are high in fat, sugar and salt, and a decline of physical activity. As these determinants of poor health are preventable, we will work with Indigenous men and thei ....Promoting fit bodies, healthy eating and physical activity among Indigenous Australian men. Overall, the physical and emotional health of our Indigenous people is the worst in Australia. A major contributing factor is the significant lifestyle changes that have eroded traditional ways of life. These include the adoption of diets that are high in fat, sugar and salt, and a decline of physical activity. As these determinants of poor health are preventable, we will work with Indigenous men and their communities to target cultural factors and develop health promotion strategies that can be used to improve their health.Read moreRead less
Recognising, assessing, and managing high risk stalking behaviour: An evidence-based approach. Developing effective methods of assessing and treating stalkers will directly impact the health and safety of thousands of stalking victims across Australia, and reduce the number of stalkers coming into contact with the criminal justice system.

Developing effective methods of assessing and treating stalkers will directly impact the health and safety of thousands of stalking victims across Australia, and reduce the number of stalkers coming into contact with the criminal justice system. Application of the assessment and treatment tools developed during this project by mental health and corrective services around Australia will help to reduce physical and psychological harm experienced by both stalkers and their victims. The development and implementation of practical and effective strategies that lessen the impact of stalking will reduce the burden of mental ill-health caused by stalking, increase community safety, and reduce overall levels of victimisation in Australian society.

This innovative project will investigate the experiences, understandings and perceptions of nurses working with eating disordered patients in hospital contexts. Nurses currently nursing eating disordered patients will be interviewed in depth using a semi-structured interview schedule. Interviews will be audio-recorded and transcribed verbatum. The interview transcripts will then be systematically analysed using a qualitative discourse analytic methodology. The aim will be to identify the specific discursive resources that nurses use to frame and make sense of their experiences, understandings and perceptions of nursing eating disordered patients. The project has clinical and social scientific significance, and will contribute to improved treatment outcomes.Read moreRead less
Environmental and genetic risk factors for anxiety disorders in children. Anxiety disorders provide one of the largest sources of disability affecting Australian society. The results of this study will lead to critical advances in our understanding of the causes of anxiety disorders. Having greater understanding of factors that place a child at risk for disorder will allow intervention programs to more accurately target those children and families at greatest risk.

Anxiety disorders provide one of the largest sources of disability affecting Australian society. The results of this study will lead to critical advances in our understanding of the causes of anxiety disorders. Having greater understanding of factors that place a child at risk for disorder will allow intervention programs to more accurately target those children and families at greatest risk. Given the prevalence of anxiety disorders and the significant life interference associated with these disorders, improving intervention efforts will give rise to significant enhancement in the mental health of thousands of Australian children.
