Mapping Between Cognitive Theories And Psycho-Physiological Models Of Attention System Performance, Oliver A. Guidetti, Craig P. Speelman, Peter Bouhlas

Research outputs 2022 to 2026

Declines in the capacity to sustain attention to repetitive, monotonous tasks is a phenomenon known as vigilance decrement (Endsley M, Kiris E. The out-of-the-loop performance problem and level of control in automation. 1995. Hum Factors. 37:32-64). This review compares cognitive theories with psycho-physiological models of vigilance decrement, and a gap is identified in mapping between the 2. That is, theories of vigilance decrement refer to "cognitive" resources; by contrast, psychophysiological models of the cerebral systems associated with attention explain performance functions according to neurochemical resources. A map does not currently exist in the literature that bridges the gap between cognitive …

We surveyed community members and individuals who had attended specific emergency departments for suicidal crisis. The respondents were part of a large-scale suicide prevention trial in New South Wales, Australia. The data collected included demographic characteristics, measures of help-seeking and suicide stigma. The linear regression analyses conducted sought to identify the factors …

Autonomy Versus Support: Self-Reliance And Help-Seeking For Mental Health Problems In Young People, Amelia Ishikawa, Debra Rickwood, Emily Bariola, Navjot Bhullar

Research outputs 2022 to 2026

Purpose:

Many young people with mental ill-health do not seek support, and developmental growth in self-reliance may be a barrier to help-seeking. Increasing autonomy is a positive developmental task for youth and a key aspect of resilience. This study examined the influence of perceived social support and resilience on the previously unexamined relationship between self-reliance and intentions to seek help from informal, professional, and self-help sources for mental health problems.

Methods:

An online survey was completed by a representative Australian community sample of 5,203 young people aged 12–25 years (half female), in May–June 2020.

Results:

Path analysis showed the hypothesised …

Alexithymia And Impulsivity In Combat Sports – A Tale Of Three Measures, Craig A. Harms, Oliver R. Barley

Research outputs 2022 to 2026

The purpose of this study was to compare the psychometric properties of two measures of alexithymia – the Toronto Alexithymia Scale (TAS-20) and the Perth Alexithymia Questionnaire (PAQ) – as well as the Barratt Impulsiveness Scale 11 measure of behavioural impulsivity because the psychometric properties of these scales have not been established in athletes. As part of a larger study, 298 participants completed an online survey that included the TAS-20, PAQ, and BIS 11, as well personal- (age and gender) and sport-specific (primary combat sport and level of competition) demographic measures. A unidimensional model was retained for the TAS-20. A …

Prevalence Of Distress And Its Associated Factors Among Caregivers Of People Diagnosed With Cancer: A Cross-Sectional Study, Deborah L. Kirk, Istvan Kabdebo, Lisa Whitehead

Research outputs 2022 to 2026

Aims and Objectives: To (i) determine prevalence of distress among caregivers of people living with cancer, (ii) describe caregivers’ most commonly reported problems and (iii) investigate which factors were associated with caregivers’ distress. Background: The psychological distress associated with a cancer diagnosis jointly impacts those living with cancer and their caregivers(s). As the provision of clinical support moves towards a dyadic model, understanding the factors associated with caregivers’ distress is increasingly important. Design: Cross-sectional study. Methods: Distress screening data were analysed for 956 caregivers (family and friends) of cancer patients accessing the Cancer Council Western Australia information and support line …

A Qualitative Systematic Review On The Experiences Of Homelessness Among Older Adults, Phuntsho Om, Lisa Whitehead, Caroline Vafeas, Amanda Towell-Barnard

Research outputs 2022 to 2026

Adults who experience homelessness for an extended period of time also experience accelerated ageing and other negative impacts on their general health and wellbeing. Homelessness amongst older adults is on the rise, yet there are few systematic reviews investigating their experiences. Thus, this review classifies and synthesises qualitative research findings of studies published between 1990 to 2020 that have examined the needs and challenges of homeless older adults to elucidate their journey of homelessness. Seven papers met the requirements for inclusion. Three main themes were identified in the review: - (1) Pathways to homelessness, (2) Impact of homelessness, and (3) …

How A 7-Week Food Literacy Cooking Program Affects Cooking Confidence And Mental Health: Findings Of A Quasi-Experimental Controlled Intervention Trial, Joanna Rees, Shih Ching Fu, Johnny Lo, Ros Sambell, Joshua R. Lewis, Claus T. Christophersen, Matthew F. Byrne, Robert U. Newton, Siobhan Boyle, Amanda Devine

Research outputs 2022 to 2026

Obesity and mental health disorders are rising simultaneously with shifting dietary behavior away from home cooking, toward typically nutrition-poor and energy-dense convenience meals. Food literacy strongly influences nutrition choices. Community-based cooking interventions target barriers to healthy eating and facilitate development of food literacy skills, thereby potentially increasing preparation of home-cooked meals and positively influencing health. This study of 657 healthy Australian adults explored the efficacy of a 7-week cooking program in improving cooking confidence, whether this transferred to behavior surrounding food, and/or affected mental health. Significant post-program improvements in cooking confidence and satisfaction (all p < 0.001, (Formula presented.) 1.12 large), ability to change eating habits (p < 0.001) and overcome lifestyle barriers (p = 0.005) were observed for the intervention group but not control. Participation also improved mental and general health (all p < 0.05, (Formula presented.) 0.02 small). No changes were observed for acquisition and consumption of food, or nutrition knowledge in either group. This 7-week cooking program built cooking confidence and improved general and mental health but did not change dietary behavior. To further improve nutrition related behaviors associated with better mental health, more effort is needed to recruit those with below-average nutrition knowledge and interest in cooking.
