Summary
Epidemiological studies show that 1 in 5 Australians aged 18-24 are diagnosed as having an alcohol use disorder. However, there is evidence to suggest that young adults may interpret the diagnostic criteria differently to older adults. The current study aims to validate the alcohol use disorder criteria in younger populations through the use of novel cognitive interviewing techniques.

Summary
This project will further develop the research opportunities of an internationally unique 15 year follow up study of the mental health of young Australians with ID. We have shown that this group has 2-3 times the risk of suffering serious emotional and behavioural problems that are an added heavy burden on the individual, their family and carers and the community. These problems often are not recognised but are as common as schizophrenia in the community.

We have shown that this group has 2-3 times the risk of suffering serious emotional and behavioural problems that are an added heavy burden on the individual, their family and carers and the community. These problems often are not recognised but are as common as schizophrenia in the community. The study will continue to use a combination of questionnaire survey and in depth interviews of the young adults and their families or carers to track the course of their mental health. The study commenced in 1990 with nearly 1000 young people with ID aged 4-18 years and their progress has been reviewed every 2-3 years in over 75% of the original group. During the next 5 years we plan to follow their mental health during the critical stage of young adult life. During this time there is the greatest risk of mental illnesses such as depression and schizophrenia and the stresses of adjusting to new daily occupations, independent living or residential care and social contact away from the family. We will be able to study the specific emotional and behavioural problems faced by young adults with the main known causes of ID such as Down, Fragile X, Prader Willi and William Syndromes, as well as those who have autism. The great benefit of a long term follow up study is that it allows us to study the links between earlier family environmental, psychological and biological factors and subsequent mental health problems. We can also demonstrate the impact that mental illness in a young person with ID has on the family and parental mental health. The findings have implications for better diagnosis, improved care and management, early intervention and prevention of these common severe and under recognized mental health problems in this disadvantaged group of young Australians and their families and carers.Read moreRead less
The Extinction Of Conditioned Fear And Its Implications For Cue Exposure Therapy

Summary
This project studies extinction of Pavlovian conditioned fear reactions in rats. Extinction of these reactions is an animal model for exposure therapy used in the treatment of anxiety disorders in people. In exposure therapy, the patient, aided by the clinician, confronts trauma-related cues in the absence of any overt danger. The intention of this therapy is to reduce the ability of the trauma-related cues to provoke the fear reactions that are undermining the patient's quality of life.

Extinction of these reactions is an animal model for exposure therapy used in the treatment of anxiety disorders in people. In exposure therapy, the patient, aided by the clinician, confronts trauma-related cues in the absence of any overt danger. The intention of this therapy is to reduce the ability of the trauma-related cues to provoke the fear reactions that are undermining the patient's quality of life. In Pavlovian conditioning, subjects (typically rats) are exposed to a signaling relation between an initially neutral stimulus (e.g., a noise) and a feared outcome (e.g., foot shock). When later repeatedly exposed to the initially neutral but now feared stimulus (the noise) in the absence of the feared outcome, the fear reactions it acquired progressively decline until eventually it fails to elicit any such reactions. The fear reactions are said to have been extinguished. There has been significant progress in understanding the psychological processes and neural mechanisms underlying the acquisition of fear reactions, but much less is known about the processes and mechanisms underlying the extinction of these reactions. The project has two general objectives. The first is to determine the conditions of extinction training that promote long-term loss of fear reactions. The second objective is to determine how the brain controls this extinction of learned fear. Achieving these aims will be significant for two reasons. First, it will contribute to understanding the mechanisms by which animals (including people) learn to adjust their behaviour to bring it into line with the current relations that exist between events in the world. Second, it will provide important information about how such adjustment is facilitated or impaired across extinction training and, thereby, contribute towards understanding both the successes and failures of cue exposure therapy for fear-related disorders.Read moreRead less
