Development and validation of the depressive vulnerability and resilience scales

Demonstrates that a personality type typified by self-perceptions tinged with a positive bias and high levels of optimism, provides protection, or resilience, from the experience of depression. Suggests that vulnerability to depression can be attributed to an inability to develop positively biased self-perceptions.

Body image in adolescent girls

This study investigated the Tripartite Influence Model of body image and eating disturbance in adolescent females. The model was found to be a satisfactory representation of the social, cultural and individual factors proposed to promote body dissatisfaction, dieting and bulimic behaviours in 14 to 18 year old girls. The portfolio presents four case situations in which the specialist knowledge of a clinical psychologist has shown to be beneficial to pediatric patients, their families, and medical staff at a major metropolitan hospital.

How individuals judge the fairness of pay

International survey data and case studies explore how individuals come to regard some ways of deciding pay as fair and others as unfair. Individuals, motivated by material and psychological self interest, but limited by social reality, interpret pay to maximise perceptions of entitlement while maintaining a positive and coherent self concept.

Beyond mental illness

The Introducing Me program was developed as a recovery-oriented intervention program for people with mental illness. Program trials revealed improvements in self-concept, self-esteem, reduced social anxiety, and overall positive feedback. This novel and innovative program has important implications for the treatment and wellbeing of persons with a severe mental illness. The Professional Portfolio discusses issues relating to the assessment and diagnosis of depression in adolescents and factors determining appropriate treatment recommendations. Four case studies are presented.

Body weight and weight loss : are health messages reaching their target?

Objective: To investigate lay peoples’ knowledge of health risks of overweight, accuracy of self-perception of body weight and perceived benefits of weight loss. Method: A nine item questionnaire was administered to a cross sectional survey of adults in metropolitan shopping centres, height and weight were measured. Results: Two hundred and nine (57% female) adults completed the survey. Thirty eight percent had a healthy BMI (18.5-24.9), 38% were overweight (BMI 25-29.9) and a further 22% were obese (BMI>30). However only 46% perceived themselves ‘overweight’, 50% considered themselves ‘just about right’ and 4% considered themselves ‘underweight’. Of those with a BMI of 25 or greater 28% considered their weight ‘just about right’. Over 80% thought ‘being overweight’ was ‘likely’ or ‘very likely’ to be a risk factor for cardiovascular disease, hypertension, diabetes and stroke; however 20% of overweight or obese individuals did not think their health would improve if they lost weight. Conclusion: A significant proportion of overweight or obese individuals do not accurately perceive their body weight and do not recognise the health advantages of weight loss despite recognising excess body weight as a risk factor for chronic diseases. Implications: Increasing the awareness of an individual’s BMI and promoting the benefits of modest weight loss maybe two underutilized strategies for population level weight control.

Total safety culture by behavior-based safety approach

Safety is a social responsibility and providing a safe working environment is the obligation of a responsible employer. Working safely can generate direct financial benefits. However, poor safety planning and management may lead to tremendous adverse effects on cost, time and quality of a project. Statutory liabilities and heavy fines directly increase project cost; losing working hours as a result of safety incident impacts on the project programme. When tradesmen are working in an unsafe site environment, the project quality may be affected. Therefore, promoting "safety" is always the very first and utmost priority in any large scale projects. Bodley (2000) argues that culture involves what people think, what they do, and what they produce. In order to provide a safe working environment, one of the best ways is to create a safety culture within the organization, because organizational-cultural factors play an important role in safety management. Geller emphasises the importance of safety culture and further states that behaviour-based safety (BBS) is a useful approach to uphold organizational safety culture. The basic premise of BBS is self-perception and the degree of self-perception will lead to pleasant safety outcomes. This degree can be measured by level of workers' involvement. When everyone in the project is accountable to safety, they will contribute positively. This paper is a case study reviewing how BBS approach fosters safety culture leading to ultimate success. The model illustrated by the case study will be useful to analyze the organizational safety culture quantitatively.

Top-down and bottom-up approaches to motor skill assessment of children : are child-report and parent-report perceptions predictive of children's performance-based assessment results?

Background/ Aim: Therapists use different types of tests, scales, and instruments to assess children's motor skills, including those classified as being top-down and bottom-up. The aim of the study was to investigate the ability of measures of children's motor skill performance from the perspectives of children and parents (a type of top-down assessment) to predict children's performance-based motor ability test results (a type of bottom-up assessment).
Methods: A convenience sample of 38 children and parents was recruited from Victoria, Australia. Motor skill performance was evaluated from a top-down perspective using the Physical Self-Description Questionnaire (PSDQ) and the Movement Assessment Battery for Children – Second Edition (MABC-2) Checklist to measure children's and parents' perspectives respectively. Motor skill performance was also evaluated from a bottom-up approach using the Bruininks-Oseretsky Test of Motor Proficiency – Second Edition (BOT-2). Data were analyzed using multiple linear regression analysis to determine whether the PSDQ or MABC-2 Checklist was predictive of the children's BOT-2 performance results.
Results: Two predictive relationships were identified based on parents' perspectives, where the total score of the MABC-2 Checklist was found to be a significant predictor of the BOT-2 Manual Coordination motor composite score, accounting for 8.35% of its variance, and the BOT-2 Strength and Agility motor composite score, accounting for 11.6% of its variance. No predictive relationships were identified between the children's self-report PSDQ perspectives and the BOT-2 performance scores.
Conclusions: Therapists are encouraged to utilize a combination of top-down and bottom-up approaches and purposefully to seek parents' and children's perspectives when evaluating children's motor skill performance.

Myths, mysteries and mates : the experiences of culturally diverse early childhood student teachers.

An initial finding of a PhD study to explore the experiences of culturally diverse early childhood student teachers was that participants found the first year of study the hardest, with peer friendships being critical to success. Through narrative interviews, recent early childhood teacher education graduates reported that making friends proved to be an important survival strategy, restoring a positive sense of self. Vartuli (2005) highlighted the importance of positive self-perception in student teachers, linking this to ongoing teaching practice. This paper discusses the importance of student friendships in relation to successfully completing the first year of teacher education.

Factors influencing students' choice of mathematics at university

 This study investigated what motivated current undergraduate mathematics students to choose to study mathematics at university. It found a diverse array of factors perceived by students as having informed their decisions. These included background factors, situational factors, self-perception, and perceptions of mathematics as a discipline

Low-frequency brain stimulation to the left dorsolateral prefrontal cortex increases the negative impact of social exclusion among those high in personal distress

The dorsolateral prefrontal cortex (DLPFC) is thought to play a key role in the cognitive control of emotion and has therefore, unsurprisingly, been implicated in the regulation of physical pain perception. This brain region may also influence the experience of social pain, which has been shown to activate similar neural networks as seen in response to physical pain. Here, we applied sham or active low-frequency (1 Hz) repetitive transcranial magnetic stimulation (rTMS) to the left DLPFC, previously shown to exert bilateral effects in pain perception, in healthy participants. Following stimulation, participants played the “Cyberball Task”; an online ball-tossing game in which the subject participant is included or excluded. Compared to sham, rTMS did not modulate behavioural response to social exclusion. However, within the active rTMS group only, greater trait personal distress was related to enhanced negative outcomes to social exclusion. These results add further support to the notion that the effect of brain stimulation is not homogenous across individuals, and indicates the need to consider baseline individual differences when assessing response to brain stimulation. This seems particularly relevant in social neuroscience investigations, where trait factors may have a meaningful effect.

Developing career aspirations of information technology students at Deakin University

It is important for students to develop informed and realistic career aspirations to gain the most value from their university studies towards achieving their initial career goals. However developing students’ career aspirations, goals, and expectations is a complex and discipline-specific process. In Information Technology (IT) no clear career development framework is evident in the literature. Recent research in Australia argues that electronic portfolios are a useful way for students to develop, articulate and document career objectives to enhance their employability. IT students at Deakin engage in formal training and assessment with respect to developing their professional skills and career understandings. Currently electronic portfolios feature as a useful method for evidencing professional competencies for employability. Through a combined quantitative and qualitative analysis of 306 students’ articulated current career aspirations, qualitative analysis of 7 staff opinions of desired student career competencies, and a quantitative analysis of 28 students’ current work personality traits assessments (Work Personality Index), this work presents an analysis of the current state of IT students’ career development. The results indicate that while students reported short-term career aspirations, navigating to their long-term career goals is going to require addressing difficult barriers such as confidence (self-perception) and motivation. This research will influence a larger program-wide endeavour to build student career competencies for employability in IT at Deakin University.

Now again

Now Again is a participatory performance made up of a series of individual and group activities that create opportunities to notice how we fit and shift in our environment. Reflecting the dance histories of the artists, the variable dynamic possibilities of the city are brought into focus through specific ‘scores’ that, as propositions for engagement, activate simple movement patterns or observations. The aim is to allow responsive noticing of the immediate environment, but also to enliven it in unexpected ways. Individuals who are participants and observers, dedicated or incidental (passers-by), become part of the disclosure of the physical and the social. The rigid structure of the city is re-imagined as a fluid, choreographic entity invested with organic qualities. Performances move between a series of city locations, each with differing activities. Designated ‘nodes’ in the city grid (certain streets, a square, a doorway, footpath, a hole in a wall or a particular tree), have been chosen for their imaginative, affective, or energetic resonances. These are ‘mapped’ by the perambulatory, physical, sensory, and relational engagement of all participants. This is a collective dance created through noticing the feelings and patterns of the physical self in the built, natural, and social environment. In some sites, the artists perform, while in others they lead a participative performance. Ephemeral, self-led, performance experiments designed to disappear into the fabric of the city, will also be invited. A mobile app enables audience participation. The app employs GPS data to trigger information specific to that site (written prompts, sounds and scored provocations).

High-intensity interval training on cognitive and mental health in adolescents

PURPOSE: Emerging literature suggests that physical activity and fitness may have a positive impact on cognitive and mental health for adolescents. The purpose of the current study was to evaluate the efficacy of two high intensity interval training (HIIT) protocols for improving cognitive and mental health outcomes (executive function, psychological wellbeing, psychological distress and physical self-concept) in adolescents.

METHODS: Participants (n=65; mean age=15.8±0.6) were randomized to three conditions: aerobic exercise program (AEP; n=21), resistance and aerobic exercise program (RAP; n=22) and control (n=22). HIIT sessions (8-10min/session) were delivered during physical education lessons or at lunchtime three times/week for 8-weeks. Assessments were conducted at baseline and immediate post-intervention to detect changes in executive function (Trail Making Test, TMT), psychological wellbeing, psychological distress and physical self-description, by researchers blinded to treatment allocation. Intervention effects were examined using linear mixed models. Cohen's d effect sizes and clinical inference were also calculated.

RESULTS: Small improvements in executive function (d=-0.32, 95%CI -9.12 to 9.77; p=0.386) and psychological wellbeing (d=0.34, 95%CI -1.73 to 2.37; p=0.252) were evident in the AEP group. Moderate improvements in executive function (d=-0.51, 95% CI -8.92 to 9.73; p=0.171), and small improvements in wellbeing (d=0.35, 95%CI -1.46 to 2.53; p=0.219) and perceived appearance (d=0.35, 95%CI -0.74 to 0.41; p=0.249), were observed for the RAP group. Mean feelings state scores improved from pre-workout to post-post workout in both HIIT conditions, with significant results for the AEP (p=0.001).

CONCLUSIONS: This study highlights the potential of embedding HIIT within the school day for improving cognitive and mental health among adolescents.

Is the perception of time pressure a barrier to healthy eating and physical activity among women?

Objectives To describe the proportion of women reporting time is a barrier to healthy eating and physical activity, the characteristics of these women and the perceived causes of time pressure, and to examine associations between perceptions of time as a barrier and consumption of fruit, vegetables and fast food, and physical activity.
Design A cross-sectional survey of food intake, physical activity and perceived causes of time pressure.
Setting A randomly selected community sample.
Subjects A sample of 1580 women self-reported their food intake and their perceptions of the causes of time pressure in relation to healthy eating. An additional 1521 women self-reported their leisure-time physical activity and their perceptions of the causes of time pressure in relation to physical activity.
Results Time pressure was reported as a barrier to healthy eating by 41 % of the women and as a barrier to physical activity by 73 %. Those who reported time pressure as a barrier to healthy eating were significantly less likely to meet fruit, vegetable and physical activity recommendations, and more likely to eat fast food more frequently.
Conclusions Women reporting time pressure as a barrier to healthy eating and physical activity are less likely to meet recommendations than are women who do not see time pressure as a barrier. Further research is required to understand the perception of time pressure issues among women and devise strategies to improve women’s food and physical activity behaviours.

Weight status and perception barriers to healthy physical activity and diet behavior

Background : Physical inactivity and insufficient fruit and vegetable consumption are key risk factors for obesity and noncommunicable diseases. Weight perceptions may affect physical activity and diet behaviors. We report current prevalence estimates of Australian adults meeting recommended levels of leisure-time physical activity (LTPA) (150 min/week or more of at least moderate-intensity physical activity (including walking) on 5 days/week) and fruit (2 servings/day) and vegetable (5 servings/day) consumption for health benefits, by weight status and perceptions.
Methods : We conducted a cross-sectional survey analysis of data for 16 314 adults from the Australian National Health Survey 2004–2005. All variables were collected by self-report. Weighted estimates were age- and gender-specific, and data were analyzed using logistic regression with acceptable weight referent categories, adjusting for covariates.
Results : Among acceptable, overweight and obese adults, the prevalence of LTPA was 26.8, 26.1 and 19.3% for men, and 27.7, 23.7 and 19.7% for women, respectively. Approximately 55 and 15% of adults consumed sufficient fruit servings/day and vegetable servings/day, respectively, and less than 5% of adults met combined LTPA and diet guidelines. Overweight decreased the odds ratio for LTPA among women but not men, and obesity decreased the odds ratio for LTPA among both men and women. Overweight perception conferred odds ratios of 0.83 (95% CI 0.70–0.97, P=0.021) for overweight men, and of 0.74 (95% CI 0.62–0.88, P=0.001) and 0.69 (95% CI 0.59–0.80, P<0.001) for obese men and women, respectively; for LTPA, whereas no significant associations were found for acceptable weight perception. No consistent associations between weight status or perceptions and diet behaviors were found.
Conclusions : Overweight perception may be another barrier to physical activity participation among men and women with excess body weight. Public health strategies might need to focus on overcoming weight perception as well as weight status barriers to adopting healthy physical activity behaviors.
