Each year, in Australia, approximately 28,000 adolescents become pregnant. The psychological, social and financial cost of adolescent pregnancy in Australia is substantial, in both the long and short term. An unexpected finding in North American studies is that a substantial number of adolescent pregnancies occur by design. Prevention programs in Australia and elsewhere assume adolescents do not wish to become pregnant and focus on educating adolescents about causes rather than consequences.

The psychological, social and financial cost of adolescent pregnancy in Australia is substantial, in both the long and short term. An unexpected finding in North American studies is that a substantial number of adolescent pregnancies occur by design. Prevention programs in Australia and elsewhere assume adolescents do not wish to become pregnant and focus on educating adolescents about causes rather than consequences. Research conducted by one of us (JAQ) found that over 75% of pregnant teenagers said they had deliberately become pregnant. Another of us (JTC) studied 1,500 Australian adolescents attitudes and beliefs about pregnancy and parenthood. The findings showed high levels of idealisation, especially in males. Males have been largely neglected in adolescent pregnancy research. The first component of this study is a survey of 500 adolescents to investigate their attitudes and beliefs about pregnancy occurring in a sexual partner, and the consequences of that event for them both. The assessment tool is a computer role-play simulation with its starting point the announcement of a pregnancy. The intervention study involves 300 adolescents and comprises viewing and discussing a video in which 4 adolescent males talk about their experiences of the consequences of pregnancy in a sexual partner. The use of 4 groups with different sequences of assessment and intervention will enable us to ascertain the effectiveness of the intervention. Of particular interest is whether the video or the role-play makes any impact on idealised attitudes and beliefs. This research is the first undertaken on adolescent male attitudes and beliefs using a computer role-play. It will provide essential information for the development of effective, male-oriented prevention programs which focus on consequences as well as causes of adolescent pregnancy.Read moreRead less

Behavioural-family-based treatment have good success rates with young children with cooperative parents, however, there are a minority who progress to chronic problems despite this. Risk and resilience factors identifying chronic patterns in early childhood are the key to early intervention. In previous research, this research team showed for the first time that callous-unemotional traits, a feature of chronic psychopathy, could be measured in children as young as 4 years, and was predictive of a range of negative outcomes. However, it was also found that the key neuropsychiatric markers characteristic of psychopathy, including reward dominance-punishment insensitivity and deficits in affective empathy, did not exist in conduct problem children prior to adolescence. Around the time of puberty, it appears that important changes occur in cognitive-affective processing styles that are associated with the adult form of psychopathy and antisocial behaviour. Thus, this research raises critical questions about the development of severe antisocial behaviour (or psychopathy) through the childhood to adolescent years. Our evidence indicates that early adolecence may be the period when intrapsychological characteristics representing chronic risk become concrete. The current research will be the first to map the development common neuropsychiatric markers (affective empathy, punishment insensitivity) of severe antisocial processes through the late childhood-adolescent period. The findings will have clear implications for models of antisocial behaviour and clinical approaches to working with conduct problem children and adolescents.Read moreRead less

Autism is associated with personal suffering and is a significant burden and stress for parents, families and carers and cost to the community. In earlier work we have demonstrated that providing a structured program of parent education and guidance to families with preschool children with autism leads to improved parental adjustment and mental health. The program also led to behavioural and developmental benefits for the child. The early secondary school years bring further stress and difficulty to adolescents with autism and their families. This project aims to assess the effectiveness of a parent education and training program for parents with autistic adolescents aged 12-14 years. If shown to be effective, this manual based intervention can be readily used by professionals to promote parent mental health, family adjustment and improve the wellbeing and outcome for adolescents with autism. As a result, family stress and the necessity of out of home care may be reduced and school participation improved.Read moreRead less

Chronic use of cannibis can impair frontal brain functioning, affecting the capacities for attention, working memory and concentration.These neurocognitive deficits bear striking similarities to those associated with the negative symptom cluster of schizophrenia,which is related to frontal brain dysfunction. The proposed study will be the first of it's kind to apply sophisticated neuroimaging techniques to investigate how long-term adolescent cannabis use effects the structure and function of the brain and to make comparative analyses with the brain changes associated with first episode schizophrenia. We predict that structural brain abnormalities that are consistent in localisation, if not in degree, will be detected in long-term cannabis using and first episode schizophreniaparticipants and that there will be even more profound abnormalities in the first episode schizophrenia cannabis users. We will use the Tower of London (TOL) task to activate certain areas associated with executive functioning (for instance attention, memory, and strategic planning). Here, we expect lower intensity activation of the prefrontal cortex during TOL performance both in the cannabis and first episode schizophrenia groups and that the activation will be lowest of all for the cannabis using first episode schizophrenia group. The methodology to be applied in this study offers a unique opportunity to enhance our understanding of the structural and functional markers of first episode schizophrenia and cannabis use in the neural substrate.Read moreRead less

Schizophrenia is a severe mental illness defined by a number of symptoms including hallucinations, delusions, social withdrawal and cognitive impairment. Factors very early in development have been suggested to induce an increased vulnerability to this illness. Recently, it was suggested that another major event, later in life, would be needed before vulnerable individuals would develop schizophrenia.

Factors very early in development have been suggested to induce an increased vulnerability to this illness. Recently, it was suggested that another major event, later in life, would be needed before vulnerable individuals would develop schizophrenia. The aim of this project is to model this two-hit hypothesis in rats. We will compare the effect of various neonatal maternal separation protocols as an early stressful event, followed by chronic treatment with the stress hormone corticosterone at various stages later in life. We will also perform a detailed anatomical study of the hippocampus of these rats. This brain area has been implicated in the development of schizophrenia in humans. We will also investigate if treatment with antipsychotic drugs can prevent or reverse behavioural and neuroanatomical changes seen in the rats. This will be the first comprehensive study to model this two-hit neurodevelopment hypothesis of schizophrenia and will provide an experimental verification of a clinical concept which is very difficult to prove in patients.Read moreRead less

This possibility is of strong concern to consumers. To date, there have been few well designed, prospective studies of this issue. Furthermore, no previous studies have specifically targeted women at increased risk because of their family history. Over the past 7 years, it has become possible to identify 2 breast cancer genes (BRCA1 and BRCA2). Female carriers of mutations in these genes with a strong family history have an estimated lifetime risk of between 35% and 85%. The Kathleen Cuningham Consortium for Research into Familial Breast Cancer (KConFab) was established 7 years ago to coordinate the collection of genetic, epidemiological and clinical data in Australian families with a dominantly inherited predisposition to breast cancer. Due to the high rate of breast cancer diagnoses in this group, and the systematic recruitment of large numbers of high risk women by KConFab, there is a unique and temporary opportunity to conduct a rigorous study to resolve this question, with sufficient numbers involved. The study is a world first, and will provide the best data to date in this area. If the study demonstrates a relationship between psychosocial factors and the development of breast cancer in women from high risk breast cancer families, subsequent identification of vulnerable individuals and the implementation of appropriate interventions may have a real impact on reducing morbidity and mortality in this population. Furthermore, the results may have implications for all women in reducing breast cancer incidence.Read moreRead less

Summary
School refusing youth consistently suffer from anxiety and sometimes depression. They become severely emotionally distressed when taken to school and experience social and academic difficulties in the short and long term as well as psychiatric illness in adulthood. Our program investigates whether treatment can be improved by enhancing psychotherapy (cognitive behaviour therapy) which helps over half of anxious school refusing children, with antidepressant-anxiety medication compared to placebo.
