Factors in youth physical activity participation : from psychological aspects to environmental correlates

Understanding influences on children's physical activity and how these vary by activity and subgroup, such as age and sex of the child, is important for informing the development of effective and targeted interventions. Two cohort studies were conducted across socioeconomic areas of Melbourne, Australia, between 2001 and 2008 among a combined sample of more than 2,700 children aged 5-6 years and 10-12 years at baseline. Data were collected via surveys, and children wore the Actigraph accelerometer for 8 days. Five individual, 10 social, and 17 physical environmental factors were significantly associated with children's physical activity. Patterns of association varied according to the age and sex of the child and also according to the type of activity. These studies provide some insights into the various levels of influence on children's physical activity. More longitudinal and intervention research is needed to better understand the mechanisms of change in children's physical activity behaviour.

The self-reported personal wellbeing of a sample of Australian injecting drug users

Aims To examine the self-reported personal wellbeing of a sample of Australian injecting drug users (IDU) using a standardized instrument and determine the key correlates of variations in self-reported personal wellbeing.

Design, setting and participants Cross-sectional survey of 881 Australian IDU.

Measurements Self-reported personal wellbeing collected using the Personal Wellbeing Index (PWI).

Findings IDU scored significantly lower than the general Australian population on the PWI and all subscales. Lower PWI scores were associated with a range of socio-demographic, drug use and other health and social characteristics. Across all PWI subscales, lower personal wellbeing scores were associated with unemployment, past 6-month mental health problems and more frequent injecting (all P < 0.05).

Conclusions The PWI is sufficiently sensitive to distinguish between IDU and the general population, and to identify key correlates of PWI among IDU. Some domains canvassed within the scale, such as health, standard of living and life achievements, are well within the scope of current intervention strategies, such as pharmacotherapy maintenance treatment and housing and employment support services. This suggests that the PWI could be useful in clinical settings by allowing structured identification of the areas of a person's life to be addressed as a part of a treatment regimen. In order to inform targeted prevention and intervention efforts, longitudinal studies of PWI and its correlates among IDU are required.

Comparing multiple discrepancies theory to affective models of subjective wellbeing

The Subjective Wellbeing (SWB) literature is replete with competing theories detailing the mechanisms underlying the construction and maintenance of SWB. The current study aimed to compare and contrast two of these approaches: multiple discrepancies theory (MDT) and an affective-cognitive theory of SWB. MDT posits SWB to be the result of perceived discrepancies between multiple standards of comparison. By contrast, affective-cognitive theory asserts that SWB is primarily influenced by trait affect, and indirectly influenced by personality and cognition through trait affect. Participants comprised 387 individuals who responded to the 5th longitudinal survey of the Australian Unity Wellbeing Index. Results of Structural Equation Modelling (SEM) indicated the poorest fit to the data for the MDT model. The affective-cognitive model also did not provide a good fit to the data. A purely affective model provided the best fit to the data, was the most parsimonious, and explained 66% of variance in SWB.

Religiosity and subjective wellbeing in Christianity, Buddhism and Taoism

The relationship between three religions (Christianity, Buddhism and Taoism) and subjective wellbeing were studied. Religiosity and spirituality-religion satisfaction were significant predictors of subjective wellbeing. A new construct of religious self-esteem and a new scale of Christianity secondary control were found as useful in explaining subjective wellbeing.

Psychological profiling of Tasmanian police officers using the COPS

This thesis examined selection processes for police candidates, and the impact of police work on well-being. Results revealed that policing impacts negatively on psychological well-being over time, and that many aspects of the stereotypic 'police personality' are not a result of selection processes, but develop over time in the role.

The psychological and physical needs of workers impacting office design

Office design needs to be based on the needs of the most important producers of profit and value for any organisation – the workforce. Drivers affecting office design have been economics – space being often viewed as a cost-centre rather than a business enabler; and more recently, ideas that office design can impact organisational culture – resulting in the adoption of more collaborative working spaces in an attempt to force interaction. What is not always considered are the actual working styles
of the individuals and their motivations nor the requirements of the work itself. There is a need to profile not only the workforce, but also the work carried out. Recent research into space requirements for work is reviewed and reported with recommendations for better consideration of the psychological and physical needs of workers for office design.

The subjective wellbeing of high-school students : validating the personal wellbeing index—school children

The Personal Wellbeing Index—School Children (PWI-SC) is designed as a parallel form of the adult PWI-A, to measure subjective wellbeing. This study examines the psychometric properties of the PWI-SC. Data from 351 students, aged between 12 and 20 years, were collected by two independent studies over the years 2005–2006. Using the combined data, the results indicate good psychometric properties for the PWI-SC. It is also found that females have higher SWB but that both genders show an age-related decline in SWB from early to mid adolescence. Notably, School satisfaction meets the criteria for a new domain for the PWI-SC and should be considered for inclusion in a future revision of the scale. The use of the PWI-SC in schools can provide important information for the development of educational policy.
