Funding Amount
$307,125.00
Summary
An interrupted time series (ITS) study involves a population observed on multiple occasions before and after the implementation of an intervention program. However, methods for statistical analysis and designing such studies have not been well developed and many statistical analyses of such studies are flawed. This proposal will investigate appropriate methods for design and analysis, and develop guidelines and software for its implementation by health researchers.

Remediation is not effective once a chronic pattern has been established. Recently, research has shown that early signs of psychopathy in children predict chronic antisocial behaviour and lack of responsiveness to traditional treatments. The current research uses a combination of experimental, longitudinal, and treatment outcome studies to examine: the effectiveness with which early signs of a callous-unemotional temperamental style, hypothesised to be an early indicator of psychopathy, can be measured in children, causal factors and correlates of callous-unemotional traits, whether such traits pose a risk for chronic antisocial behaviour, the effects of callous-unemotional traits on responsiveness to traditional family-school based treatments, and the effectiveness of an innovative method for treating it in the early years. The project leads directly to a range of clinical assessment and treatment strategies for children at risk for chronic antisocial behaviour. The project has the potential to substantially improve the effectiveness of current treatment approaches to conduct problems in children that focus on family and school management.Read moreRead less
Understanding And Influencing Physical Activity To Improve Population Health

Summary
Three of Australia's leading researchers on physical activity and population health will use new NHMRC program grant funding to consolidate and extend their already internationally-recognised studies. Doing regular physical activity is very important for maintaining good health. It helps to prevent weight gain, type 2 diabetes, heart disease and breast and colon cancer.

Doing regular physical activity is very important for maintaining good health. It helps to prevent weight gain, type 2 diabetes, heart disease and breast and colon cancer. Unfortunately, most Australian adults are not active enough for health benefits. Rates of overweight and obesity are increasing rapidly; more than 50% of Australian adults are above the healthy weight range. Rates of type 2 diabetes have doubled in the past 20 years. New ideas and practical tools are therefore needed to tackle these serious ‘diseases of inactivity’. To this end, Professors Neville Owen, Adrian Bauman and Wendy Brown will bring together innovative and practically useful scientific approaches drawn from psychology, epidemiology and exercise physiology. The approach is interdisciplinary – it combines theories and methods from their individual disciplines in an innovative manner, within a public health framework. Their research to date has developed better methods for measuring people’s exercise habits and has provided new insights into how personal, social and environmental circumstances can make people less active. They have also shown how to design and deliver wide-reaching programs for different social groups and evaluated their effectiveness. Their new research program will build on and significantly extend these ideas and approaches into new areas.For example, they will develop new measures of incidental physical activity and sedentary behaviour and will develop and test new, complex community interventions.Their new program will involve in-depth study of some of the most challenging researchproblems in an important and under-researched area of public health. They will further combine their disciplines and the skills of their research team in new, creative and practical ways, to answer important research questions about physical activity and population health. These ideas and approaches will be used to identify practical ways to help more people to be more physically active.Read moreRead less

Summary
The program will focus on the 'diseases of inactivity' and will look at factors like obtaining accurate statistics on rates of inactivity and better statistics on which social groups are least active. It will look at: • the types of activity that are best for different people; • what the best types of exercise programs are; • the types of information campaigns that will be most effective; and • how community amenities and local environments might be used to help people to be active in ways that ....The program will focus on the 'diseases of inactivity' and will look at factors like obtaining accurate statistics on rates of inactivity and better statistics on which social groups are least active.

A Multisite Randomised Controlled Trial Of The Adolescent Cannabis Check-up

Summary
Recent Australian surveys cannabis use is more common than tobacco use among 14-19 year old (24.6% vs. 20.2%). More than 200,000 14-19 year olds have used cannabis in the last month and 7.1% report daily use. The population prevalence of cannabis dependence increases throughout adolescence, with a rate of 30% among those who use cannabis more than five times per year.

More than 200,000 14-19 year olds have used cannabis in the last month and 7.1% report daily use. The population prevalence of cannabis dependence increases throughout adolescence, with a rate of 30% among those who use cannabis more than five times per year. Although experimentation is a normal part of adolescent development, regular cannabis use by young people exposes them to the negative effects of cannabis at a time of rapid development and transitions in life roles. There have been no studies reported of interventions suitable for adolescents with cannabis problems who are not seeking treatment but are causing great concern for their families, schools and communities. The Adolescent Cannabis Check-up (ACCU) fills this serious gap by providing adolescents with an opportunity to objectively assess their cannabis use and develop strategies for change in a non-judgemental environment. The ACCU is a 2 session intervention: assessment and a follow-up session of personalised feed-back and brief skills-based therapy. Recruitment may be either direct or via a concerned family member. This novel approach provides parents with telephone coaching, and supporting booklets, on techniques to encourage their young person to participate. A feasibility study of 80 families has found more than 50% were able to do so. That study of 55 adolescents found a significant reduction in levels of cannabis use and an abstinence rate of 24.2% 3 months following participation in the ACCU. This project wll involve a multi-site RCT to compare the impact of the ACCU with a delayed treatment control group, on levels of cannabis use, dependence, and cannabis-related problems. This project would fill a gap in treatment service models and involve families in an initiative to assist young people to develop motivation and skills to abstain from problematic cannabis use.Read moreRead less

It makes use of the powers of modern computing and telecommunications. It uses information the person provides to personally tailor advice and assistance to smokers as they progress from beginning to think about quitting through to being a stable, happy non-smoker. In particular, we are interested in the relative value of detailed advice as compared with the capacity of modern messaging technology (SMS, voice, images) to provide a set of prompts and reminders that help smokers manage a quit attempt and help prevent them relapsing back to smoking. Once we have developed the interventions, we will subject them to a rigorous scientific trial to see how effective they are and also how cost-effective they prove. Our hope is that these programs will provide a cheap, accessible and effective way of helping smokers to quit and thus help reduce the huge toll of smoking-related disease.Read moreRead less
