Averting Uncertainty: A Practical Guide To Physical Activity Research In Australian Schools, Jerome N. Rachele, Thomas F. Cuddihy, Tracy L. Washington, Steven M. Mcphail

Australian Journal of Teacher Education

Preventative health has become central to contemporary health care, identifying youth physical activity as a key factor in determining health and functioning. Schools offer a unique research setting due to distinctive methodological circumstances. However, school-based researchers face several obstacles in their endeavour to complete successful research investigations; often confronted with complex research designs and methodological procedures that are not easily amenable to school contexts. The purpose of this paper is to provide a practical guide for teachers (both teacher educators and teaching practitioners) seeking to conduct physical activity-based research in Australian school settings, as well as discuss research practices. The …

Review Of Physical Activity Among Indigenous People, Caitlin A. Gray, Rona Macniven, Neil J. Thomson

Research outputs 2013

Physical activity is important for all Australians, particularly in the prevention, management and treatment of chronic conditions, and for social and emotional wellbeing. Chronic health conditions, including cardiovascular conditions, endocrine conditions (such as diabetes), and certain cancers, account for 70% of the observed difference in the burden of disease between the Indigenous and non-Indigenous populations. Modifiable risk factors, particularly behavioural determinants such as physical activity, can help to reduce the extent and impact of these conditions, and assist in the prevention, management and treatment of disease. The levels and impacts of physical inactivity are greater for Indigenous people than they …

Creating Cultural Empathy And Challenging Attitudes Through Indigenous Narratives, Cobie Rudd, Moira Sim, Colleen Hayward, Toni Wain

Research outputs 2013

The poorer health status of Indigenous Australians has been largely attributed to social disadvantage and their marginalisation within mainstream society (Marmot, 2011). This includes access to health care, as well as proximity to health services, availability and cultural appropriateness of health services, transport availability, health insurance, the affordability of health services and patient proficiency in English (AIHW, 2011).

The interpersonal attitudes and behaviours of non-Indigenous health providers, both conscious and unconscious, are also known to contribute to disparities in treatment, impairment of communication between health providers and patients, and consequently, patients’ mistrust of the health system due to negative past …

Retinal Vascular Biomarkers For Early Detection And Monitoring Of Alzheimer's Disease, Shawn Frost, Yogi Kanagasingam, Hamid Sohrabi, J Vignarajan, P Bourgeat, Olivier Salvado, Victor Villemagne, Christopher Rowe, S Lance Macaulay, Cassandra Szoeke, Kathryn A. Ellis, David Ames, Colin L. Masters, Stephanie Rainey-Smith, Ralph N. Martins

Research outputs 2013

The earliest detectable change in Alzheimer's disease (AD) is the buildup of amyloid plaque in the brain. Early detection of AD, prior to irreversible neurological damage, is important for the efficacy of current interventions as well as for the development of new treatments. Although PiB-PET imaging and CSF amyloid are the gold standards for early AD diagnosis, there are practical limitations for population screening. AD-related pathology occurs primarily in the brain, but some of the hallmarks of the disease have also been shown to occur in other tissues, including the retina, which is more accessible for imaging. Retinal vascular changes …

Buffart, Joeri Kalter, Mai Jm Chinapaw, Martijn W. Heymans, Neil K. Aaronson, Kerry S. Courneya, Paul B. Jacobsen, Robert Newton, Irma M. Verdonck-De Leeuw, Johannes Brug

Research outputs 2013

Effective interventions to improve quality of life of cancer survivors are essential. Numerous randomized controlled trials have evaluated the effects of physical activity or psychosocial interventions on health-related quality of life of cancer survivors, with generally small sample sizes and modest effects. Better targeted interventions may result in larger effects. To realize such targeted interventions, we must determine which interventions that are presently available work for which patients, and what the underlying mechanisms are (that is, the moderators and mediators of physical activity and psychosocial interventions). Individual patient data meta-analysis has been described as the ‘gold standard’ of systematic review …

The Validity Of The Distress Thermometer In Prostate Cancer Populations, Suzanne Chambers, Leah Zajdlewicz, Danny R. Youlden, Jimmie C. Holland, Jeff Dunn

Research outputs 2013

Background: The Distress Thermometer (DT) is widely recommended for screening for distress after cancer. However, the validity of the DT in men with prostate cancer and over differing time points from diagnosis has not been well examined. Method: Receiver operating characteristics analyses were used to evaluate the diagnostic accuracy of the DT compared with three commonly used standardised scales in two prospective and one cross-sectional survey of men with prostate cancer (n = 740, 189 and 463, respectively). Comparison scales included the Impact of Event Scale – Revised (IES-R, Study 1), the Hospital Anxiety and Depression Scale (HADS, Study 2) …

A Blood-Based Predictor For Neocortical Aβ Burden In Alzheimer's Disease: Results From The Aibl Study, Samantha Burnham, Noel Faux, William Wilson, Simon Laws, David Ames, Justin Bedo, Ashley Bush, James Doecke, Kathryn Ellis, Richard Head, Gareth Jones, Harri Kiiveri, Ralph N. Martins, Alan Rembach, Christopher Rowe, Olivier Salvado, S Lance Macaulay, Colin Masters, Victor Villemagne

Research outputs 2013

Dementia is a global epidemic with Alzheimer’s disease (AD) being the leading cause. Early identification of patients at risk of developing AD is now becoming an international priority. Neocortical Aβ (extracellular β-amyloid) burden (NAB), as assessed by positron emission tomography (PET), represents one such marker for early identification. These scans are expensive and are not widely available, thus, there is a need for cheaper and more widely accessible alternatives. Addressing this need, a blood biomarker-based signature having efficacy for the prediction of NAB and which can be easily adapted for population screening is described. Blood data (176 analytes measured in …

Internet-Based Photoaging Within Australian Pharmacies To Promote Smoking Cessation: Randomized Controlled Trial, Oksana Burford, Moyez Jiwa, Owen B. Carter, Richard Parsons, Delia Hendrie

Research outputs 2013

Background: Tobacco smoking leads to death or disability and a drain on national resources. The literature suggests that cigarette smoking continues to be a major modifiable risk factor for a variety of diseases and that smokers aged 18-30 years are relatively resistant to antismoking messages due to their widely held belief that they will not be lifelong smokers. Objective: To conduct a randomized controlled trial (RCT) of a computer-generated photoaging intervention to promote smoking cessation among young adult smokers within a community pharmacy setting. Methods: A trial was designed with 80% power based on the effect size observed in a …

Dietary Patterns Associated With Alzheimer's Disease And Related Chronic Disease Risk: A Review, Samantha L. Gardener, Stephanie R. Rainey-Smith, Jennifer Keogh, Suzanne Mathieson, Ralph N. Martins

Research outputs 2013

The world’s population is growing older due to improved healthcare and nutrition. As a result, Alzheimer’s disease (AD) prevalence is rapidly increasing. The focus of the current research climate is shifting from understanding AD pathology and diagnosis to primary prevention and intervention strategies. Diet represents one potential intervention strategy accessible to all. Accumulating evidence suggests diet plays a major role in risk and development of AD and AD-related chronic diseases of the periphery like cardiovascular disease (CVD) and diabetes. This paper reviews studies that have explored the relationship between “a priori” dietary patterns, AD and AD-related chronic disease risk. The …

Review Of Ear Health And Hearing Among Indigenous Australians, Jane F. Burns, Neil J. Thomson

Research outputs 2013

Indigenous Australians experience some of the highest levels of ear disease and hearing loss in the world, with rates up to ten times more than those for non-Indigenous Australians [4]. Children and adolescents are particularly vulnerable to ear infections. The most common ear disease among Indigenous children is otitis media (OM), which is inflammation/infection of the middle ear typically caused by bacterial and viral pathogens. Indigenous children living in urban, rural and, particularly, remote areas, are more likely than their non-Indigenous counterparts to have OM at younger ages, more often, at a greater level of severity, and with more likelihood …

Patterns Of Physical And Psychological Development In Future Teenage Mothers, Daniel Nettle, Thomas E. Dickins, David A. Coall, Paul De Monrnay Davis

Research outputs 2013

Background and objectives: Teenage childbearing may have childhood origins and can be viewed as the outcome of a coherent reproductive strategy associated with early environmental conditions. Life-history theory would predict that where futures are uncertain fitness can be maximized through diverting effort from somatic development into reproduction. Even before the childbearing years, future teenage mothers differ from their peers both physically and psychologically, indicating early calibration to key ecological factors. Cohort data have not been deliberately collected to test life-history hypotheses within Western populations. Nonetheless, existing data sets can be used to pursue relevant patterns using socioeconomic variables as indices …

Physical Activity: Its Implication On Attention Span And Quality Of Life In Children With Autism Spectrum Disorders, Beron W.Z. Tan, Lynne Cohen, Julie A. Pooley

Research outputs 2013

This study examined the effects of physical activity on the attention span and health-related quality of life (HRQoL) of autism spectrum disorder (ASD) children in Singapore. Male participants (N = 12) aged 2-6 years, diagnosed with ASD were randomly assigned to either a physical activity or non-physical activity group. In the physical activity group, participants were administered 8 tri-cycling sessions; both groups of participants were measured for their attention span, and their parents completed the HRQoL questionnaires. Results indicate that as the exercise increases, the physical activity group demonstrated increasingly longer duration of attention span. These results extend the findings …

The Influence Of Prior Relationship On Perceptions Of Stalking: A Comparison Of Laypersons, Nonspecialist Police Officers And Specialist Police Officers, Adrian J. Scott, Keri Nixon, Lorraine Sheridan

Research outputs 2013

The current research examined the influence of prior relationship on perceptions of stalking, and compared the perceptions of laypersons, nonspecialist police officers, and specialist police officers. Two studies employed experimental designs where participants were presented with one of three vignettes in which the nature of the prior relationship was manipulated so that the perpetrator and victim were portrayed as strangers, acquaintances, or ex-partners. Participants comprised 101 nonspecialist police officers and 108 laypersons in Study 1, and 49 specialist police officers and 49 nonspecialist police officers in Study 2. Findings indicate that nonspecialist police officers and laypersons shared the common misperception …

Framing And Perceptions Of Stalking: The Influence Of Conduct Severity And The Perpetrator-Target Relationship, Adrian J. Scott, Nikki Rajakaruna, Lorraine P. Sheridan

Research outputs 2013

Research has demonstrated that the way in which questions are presented (i.e. framed) has the capacity to influence responses to subsequent questions. In the context of stalking, perception research has often been framed in terms of whether or not particular behaviours constitute stalking. The current research investigates whether the framing of the opening question (question frame), conduct severity and the perpetrator target relationship influence perceptions of stalking. Two studies employed experimental 3 3 independent factorial designs: one to examine question frame and conduct severity, the other to examine question frame and the perpetrator target relationship. Participants in both studies (total …

Psychological Resilience Of Western Australian Police Officers: Relationship Between Resilience, Coping Style, Psychological Functioning And Demographics, Gemma M. Balmer, Julie Ann Pooley, Lynne Cohen

Research outputs 2013

This study examines the relationships between resilience, coping style, psychological functioning and the demographic variables of gender, age, rank and length of service in a sample of 285 Western Australian Police officers. Regression analysis indicated that resilience was predicted by greater use of rational coping and less use of emotional coping, but not psychological functioning. Increased age, rank and length of service were all correlated with significantly lower resilience scores. Significant differences in coping styles were found for all demographic variables. Implications of these findings and recommendations for future research are discussed.

Does The Cognitive Reflection Test Measure Cognitive Reflection? A Mathematical Modeling Approach, Guillermo J. Campitelli, Paul Gerrans

Research outputs 2013

We used a mathematical modeling approach, based on a sample of 2,019 participants, to better understand what the cognitive reflection test (CRT; Frederick In Journal of Economic Perspectives, 19, 25–42, 2005) measures. This test, which is typically completed in less than 10 min, contains three problems and aims to measure the ability or disposition to resist reporting the response that first comes to mind. However, since the test contains three mathematically based problems, it is possible that the test only measures mathematical abilities, and not cognitive reflection. We found that the models that included an inhibition parameter (i.e., the probability …
