- Description: Falls and their injury outcomes have count distributions that are highly skewed toward the right with clumping at zero, posing analytical challenges. Different modelling approaches have been used in the published literature to describe falls count distributions, often without consideration of the underlying statistical and modelling assumptions. This paper compares the use of modified Poisson and negative binomial (NB) models as alternatives to Poisson (P) regression, for the analysis of fall outcome counts. Four different count-based regression models (P, NB, zero-inflated Poisson (ZIP), zero-inflated negative binomial (ZINB)) were each individually fitted to four separate fall count datasets from Australia, New Zealand and United States. The finite mixtures of P and NB regression models were also compared to the standard NB model. Both analytical (F, Vuong and bootstrap tests) and graphical approaches were used to select and compare models. Simulation studies assessed the size and power of each model fit. This study confirms that falls count distributions are over-dispersed, but not dispersed due to excess zero counts or heterogeneous population. Accordingly, the P model generally provided the poorest fit to all datasets. The fit improved significantly with NB and both zero-inflated models. The fit was also improved with the NB model, compared to finite mixtures of both P and NB regression models. Although there was little difference in fit between NB and ZINB models, in the interests of parsimony it is recommended that future studies involving modelling of falls count data routinely use the NB models in preference to the P or ZINB or finite mixture distribution. The fact that these conclusions apply across four separate datasets from four different samples of older people participating in studies of different methodology, adds strength to this general guiding principle. © 2009 Elsevier Ltd.

- Description: Existing research applying the personal wellbeing index (PWI) in China is restricted to urban and rural samples. There are no studies for Chinese off-farm migrants. The specific aims of this study are: (a) ascertain whether Chinese off-farm are satisfied with their lives; (b) investigate the equivalence of the PWI in terms of its psychometric properties; and (c) examine whether the responses to the PWI from participants falls within the normative range predicted by the Theory of Subjective Wellbeing Homeostasis. The PWI demonstrated good psychometric performance in terms of its reliability and validity and was consistent with previous studies for Western and non-Western samples. The data revealed a moderate level of subjective well-being (PWI score = 62.6). While Chinese off-farm migrants lead hard lives, the PWI was within the normative range predicted for Chinese societies by the Theory of Subjective Wellbeing Homeostasis. A likely explanation for this finding rests with the circular nature of migration in China. When China’s off-farm migrants find it too difficult to cope in the cities, most have the fallback position that they can return to their homes in the countryside. This option provides an external buffer to minimize the inherent challenges of life which would otherwise impinge on the life satisfaction of China’s off-farm migrants

- Description: Fighting wildland fire is a physically demanding occupation. Wildland firefighters need to be physically fit to work safely and productively. To determine whether personnel are fit for duty, many firefighting agencies employ physical competency tests, such as the pack hike test (PHT). The PHT involves a 4.83-km hike over level terrain carrying a 20.4-kg pack within a 45-min period. The PHT was devised to test the job readiness of US wildland firefighters but is also currently used by some fire agencies in Australia and Canada. This review discusses the history and development of the PHT with emphasis on the process of test validation. Research-based training advice for the PHT is given, as well as discussion of the risks associated with completing the PHT. Different versions and modifications to the PHT have emerged in recent years and these are discussed with regard to their validity. Finally, this review addresses the relevance and validity of the PHT for Australian and Canadian wildland firefighters. Statement of Relevance: This paper reviews the history, development and validity of the PHT, an internationally recognised and utilised wildland firefighter work capacity test. It is concluded that while the PHT has general content validity for US wildland firefighters, verification of its reliability, criterion and construct validity is still needed.

- Description: In six experiments, subjects judged the sizes of squares that were presented visually and/or haptically, in unimodal or bimodal conditions. We were interested in which mode most affected size judgments in the bimodal condition when the squares presented to each mode actually differed in size. Three factors varied: whether haptic exploration was passive or active, whether the choice set from which the subjects selected their responses was visual or haptic, and whether cutaneous information was provided in addition to kinesthetic information. To match the task for each mode, visual presentations consisted of a cursor that moved along a square pathway to correspond to the haptic experience of successive segments revealed during exploration. We found that the visual influence on size judgments was greater than the influence of haptics when the haptic experience involved only kinesthesis, passive movement, and a visual choice set. However, when cutaneous input was added to kinesthetic information, size judgments were most influenced by the haptic mode. The results support hypotheses of sensory integration, rather than capture of one sense by the other.

- Description: Background: Falls are a significant threat to the safety, health and independence of older citizens. Despite the now substantial evidence about effective falls prevention interventions, translation into falls reductions has not yet been fully realised. While the hip fracture rate is decreasing, the number and rate of fall-related hospital admissions among older people is increasing. The challenge now is to deliver the most effective interventions efficiently at a population level, and for these interventions to be taken up by older people. Objective: To support the development, and evaluation of, effective falls prevention policy and practice in the state of Victoria, Australia. Methods: The RE-AIM model (Reach, Efficacy, Adoption, Implementation, Maintenance) was used to identify strategies for an effective programme. Research objectives were developed to support the strategies. These include: (1) identification of subgroups of older people most frequently admitted to hospital for falls; (2) examining the acceptability of established falls interventions; (3) identification of factors that encourage and support relevant lifestyle changes; (4) identifying opportunities to incorporate confirmed interventions in existing programmes and services; (5) developing guidelines for sustainability. The research results will subsequently guide strategy details for the falls prevention plan. RE-AIM will provide the framework for the evaluation structure. Outcome measures: Measures to monitor the implementation of the selected interventions will be determined for each intervention, based on the five key factors of the RE-AIM model. The overall effect of the falls prevention plan will be monitored by time series analysis of fall-related hospital admission rates for community-dwelling older people.

- Description: Background: Much evidence has accumulated over the last three decades that low social support is related to both mental and physical health. Despite this large and convincing literature, reviewers have noted that there exists remarkably little evidence that social support can be increased by an appropriate intervention. This study reports on the development and evaluation of a new intervention for social support which takes account of the stress-buffering and direct effect models. Method: Eighty-one individuals scoring low on social support were randomly allocated to the intervention or a waiting-list control condition. Treatment consisted of 10 weekly sessions administered in a group format, and 49 participants (nine males) completed assessments at the beginning and end of a 10-week period, and at 10-week follow-up (intervention condition only). Results: The intervention proved to be successful at increasing functional support but not structural support. The intervention was also successful in increasing the social skill of self-disclosure, and decreasing depression. Gains made between pre- and post-treatment were maintained at 10-week follow-up. Conclusions: Based on published analyses of the effects of social support on health, the results imply that the intervention would be useful for stress-buffering purposes, but not for the general health-promoting effects that are associated with good social integration. © 2011 The Authors.

- Description: Background: The development of e-mental health interventions to treat or prevent mental illness and to enhance wellbeing has risen rapidly over the past decade. This development assists the public in sidestepping some of the obstacles that are often encountered when trying to access traditional face-to-face mental health care services. Objective: The objective of our study was to investigate the posttreatment effectiveness of five fully automated self-help cognitive behavior e-therapy programs for generalized anxiety disorder (GAD), panic disorder with or without agoraphobia (PD/A), obsessive-compulsive disorder (OCD), posttraumatic stress disorder (PTSD), and social anxiety disorder (SAD) offered to the international public via Anxiety Online, an open-access full-service virtual psychology clinic for anxiety disorders. Methods: We used a naturalistic participant choice, quasi-experimental design to evaluate each of the five Anxiety Online fully automated self-help e-therapy programs. Participants were required to have at least subclinical levels of one of the anxiety disorders to be offered the associated disorder-specific fully automated self-help e-therapy program. These programs are offered free of charge via Anxiety Online. Results: A total of 225 people self-selected one of the five e-therapy programs (GAD, n = 88; SAD, n = 50; PD/A, n = 40; PTSD, n = 30; OCD, n = 17) and completed their 12-week posttreatment assessment. Significant improvements were found on 21/25 measures across the five fully automated self-help programs. At postassessment we observed significant reductions on all five anxiety disorder clinical disorder severity ratings (Cohen d range 0.72-1.22), increased confidence in managing one's own mental health care (Cohen d range 0.70-1.17), and decreases in the total number of clinical diagnoses (except for the PD/A program, where a positive trend was found) (Cohen d range 0.45-1.08). In addition, we found significant improvements in quality of life for the GAD, OCD, PTSD, and SAD e-therapy programs (Cohen d range 0.11-0.96) and significant reductions relating to general psychological distress levels for the GAD, PD/A, and PTSD e-therapy programs (Cohen d range 0.23-1.16). Overall, treatment satisfaction was good across all five e-therapy programs, and posttreatment assessment completers reported using their e-therapy program an average of 395.60 (SD 272.2) minutes over the 12-week treatment period. Conclusions: Overall, all five fully automated self-help e-therapy programs appear to be delivering promising high-quality outcomes; however, the results require replication. © Britt Klein, Denny Meyer, David William Austin, Michael Kyrios.

- Description: This study evaluated the effectiveness of the NSW Restraint Fitting Station Network in preventing incorrect use of rearward facing and forward facing child restraints. The way children used restraints was observed randomly as they arrived at observation sites during a cross-sectional ecological study across New South Wales, Australia. Trained researchers examined restraint system installation once the child left the vehicle. A structured interview was also conducted with the driver. Logistic regression was used to examine the association between parental report of ever having the restraint checked at a Restraint Fitting Station and whether or not the restraint was used correctly, while controlling for potential confounders and accounting for the complex sample design. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. The results demonstrated that children of respondents who did not use Restraint Fitting Stations were 1.8 times more likely to be incorrectly using their restraints (95% CI 1.1–2.8) than children of Restraint Fitting Station users. Regardless of whether or not a Restraint Fitting Station had been used, there was a trend towards a greater likelihood of incorrect restraint use as the length of restraint ownership increased (OR 1.3 95% CI 1.0–1.7). These results are important for developing strategies aimed at reducing child occupant casualties by reducing the rate of incorrect restraint use, and support programs encouraging the use of Restraint Fitting Stations and similar services as a countermeasure to incorrect use.

- Description: Effective global climate change responses must take account of the likely incidence of resource related conflicts in the 21st century. Consequently, developing effective responses to global climate change will require the replacement of rights-based approaches to states’ sovereignty in favour of responsibilities-based models of political authority. Among other things, responsibilities-based statehood would support the introduction of stronger compliance and monitoring mechanisms in states’ international dealings. Responsibilities-based statehood would establish new institutions and structures to alleviate the risks of grand-scale and recurrent conflict arising from global climate change impacts such as loss of habitable and arable land, and redistributions in freshwater resources. This paper argues that establishing a broadly accepted model of collective responsibility will be essential to the successful implementation of climate change mitigation and adaptation strategies since these rely upon political actors, structures and institutions for international development and implementation. Establishing new principles for recognising and determining collective responsibilities and achieving these goals will require the abandonment of states’ individuated rights-based claims to sovereign independence.

- Description: There is mounting evidence in clinical trials that therapist-assisted Internet cognitive behavior therapy (TAICBT) is efficacious in the treatment of depression and anxiety. Nevertheless, many clinical service providers (both individuals and organizations) question whether offering this form of treatment in clinical practice is feasible. As such, having information on the factors involved in the development of this service is essential. In this article, we describe the steps taken to develop a TAICBT service that registered professionals and students (under supervision) can use with clients suffering from symptoms of depression, generalized anxiety, and panic disorder. We share salient decisions made in developing this web application and the necessary unit policies and procedures. We also offer lessons learned and practical recommendations to providers who may want to translate this promising TAICBT research into practice.

- Description: Difficulties with emotion and its regulation are of central importance to the etiology and course of depression. The current study investigated these constructs in relation to childhood and adolescence by comparing the emotional functioning of 170 9- to 15-year-olds reporting high levels of depressive symptoms (HD) to a matched sample of 170 children and adolescents reporting low levels of depressive symptoms (LD). Compared to LD, HD participants reported significantly greater shame proneness, poorer functioning on emotion regulation competencies (emotional control, self-awareness and situational responsiveness), less healthy emotion regulation strategy use (less reappraisal and greater suppression), and lower levels of guilt proneness. Empathic concern did not differ between the two groups. The findings enhance current knowledge by providing a more comprehensive profile of the emotional difficulties experienced by children and adolescents with elevated depressive symptoms. © 2011 Springer Science+Business Media, LLC.

- Description: The field of Internet interventions is growing rapidly. New programs are continually being developed to facilitate health and mental health promotion, disease and emotional distress prevention, risk factor management, treatment, and relapse prevention. However, a clear definition of Internet interventions, guidelines for research, and evidence of effectiveness have been slower to follow. This article focuses on the quality standardization of research on Internet-delivered psychological and behavioural interventions. Although the science underpinning Internet interventions is just starting to be established, across research studies there are often conceptual and methodological difficulties. The authors argue that this situation is due to the lack of universally accepted operational guidelines and evaluation methods. Following a critical appraisal of existing codes of conduct and guidelines for Internet-assisted psychological and health interventions, the authors developed a framework of guidelines for Internet intervention research utilizing aspects of facet theory (Guttman & Greenbaum, 1998). The framework of facets, elements, and guidelines of best practice in reporting Internet intervention research was then sent to several leading researchers in the field for their comment and input, so that a consensus framework could be agreed on. The authors outline 12 key facets to be considered when evaluating and reporting Internet intervention studies. Each facet consists of a range of recommended elements, designed as the minimum features for reporting Internet intervention studies. The authors propose that this framework be utilized when designing and reporting Internet intervention research, so results across studies can be replicated, extended, compared, and contrasted with greater ease and clarity.

- Description: The graded response model, which is based on item response theory, was used to evaluate the psychometric properties of adult self-ratings (N = 852) of the attention deficit/hyperactivity disorder inattention, hyperactivity, and impulsivity symptoms presented in the Current Symptoms Scale. This scale has four ordered response categories. The results for the discrimination parameters showed that all symptoms were generally good for discriminating their respective latent traits. For virtually all symptoms, their threshold values showed that they were especially good at representing the appropriate traits from around the mean trait level onward. The item information function values for most symptoms indicated reasonable reliability from approximately the mean trait level onward. All these findings are new and extend existing psychometric information for adult self-ratings of the attention deficit/hyperactivity disorder symptoms in the Current Symptoms Scale.

- Description: Objective: The two-parameter logistic model (2PLM) was used to evaluate the psychometric properties of the inattention (IA) and hyperactivity/impulsivity (HI) symptoms. Method: To accomplish this, parents and teachers completed the Disruptive Behavior Rating Scale (DBRS) for a group of 934 primary school-aged children. Results: The results for the discrimination parameters showed that all the IA and HI symptoms for both groups of respondents were generally good for discriminating those with and without IA and HI, respectively. For virtually all symptoms, their threshold values showed endorsement of the symptoms when the underlying trait levels were at least 1 to 1.5 SD above the mean. The item information function values for most symptoms indicated reasonable reliability from around the mean trait levels to moderately high trait levels. Conclusion: These findings indicate good discrimination and reliability for parent and teacher ratings of the DBRS for identifying children with relatively high levels of the ADHD symptoms.

- Description: Objective: To identify independent factors associated with caregiver supervision levels at beaches. Methods: Children (aged 1-14 years) engaged in beach play and their caregivers were observed at Australian beaches during September-April, 2008/09. Caregiver, child, and environmental factor data were collected and recorded on a validated observation instrument. The main outcome of interest was a continuous measure of supervision. After adjusting for potential clustering by beach/state, multivariable linear regression was used to identify independent factors associated with caregiver supervision. Results: Four independent predictors of supervision and one interaction effect (child age by the caregiver and child position on beach) were identified. Caregivers who were supervising from a different position to where the child was playing were less likely to provide high supervision, as were older caregivers (>35 years) compared to younger caregivers (≤34 years). Compared to children playing alone, children playing with one, or two or more others were less likely to receive high supervision, and children aged 1-4 years were likely to receive higher supervision than older children. Conclusion: This study provides new knowledge about underlying factors associated with the level of caregiver supervision in beach settings. Future studies should continue to explore independent predictors of supervision so that effective programmes, which focus on caregiver supervision, can be targeted to address poor supervision practices.

The purpose of the current study was to determine the role of self-presentation concerns on the frequency of choking within the context of a recently proposed self-presentation model. Experienced field hockey players (N = 45) were randomly assigned to one of five groups (i.e., performance-contingent monetary incentive, video camera placebo, video camera self-presentation, audience, or combined pressure), before taking penalty strokes in low- and high-pressure phases. Results indicated that groups exposed to self-presentation manipulations experienced choking, whereas those receiving motivational pressure treatments decreased anxiety and increased performance under pressure. Furthermore, cognitive state anxiety mediated the relationship between the self-presentation group and performance. These findings provide quantitative support for the proposed self-presentation model of choking, while also holding implications for anxiety manipulations in future sport psychology research. © 2011 Human Kinetics, Inc.

- Description: Objective To examine the appropriateness of different statistical models in analysing falls count data. Methods Six count models (Poisson, negative binomial (NB), zero-inflated Poisson (ZIP), zero-inflated NB (ZINB), hurdle Poisson (HP) and hurdle NB (HNB)) were used to analyse falls count data. Empirical evaluation of the competing models was performed using model selection criteria and goodness-of-fit through simulation. Data used were from a prospective cohort study of women aged 40-80 years. Results Of the 465 women analysed, 330 (71%) did not fall at all. The analyses identified strong evidence of overdispersion in the falls data. The NB-based regression models (HNB, ZINB, NB) were better performed than the Poisson-based regression models (Poisson, ZIP, HP). Vuong tests favoured the HNB model over the NB and ZINB models and the NB model over the ZINB model. Model accuracy measures and Monte Carlo simulation of goodness-of-fit confirmed the lack of fit of the Poissonbased regression models and demonstrated the best fit for the HNB model with comparable good fit for the ZINB and NB models. Conclusions Falls count data consisting of a considerable number of zeros can be appropriately modelled by the NBbased regression models, with the HNB model offering he best fit. The evaluation procedure presented in this aper provides a defensible guideline to appropriately odel falls or similar count data with excess zeros.

- Description: Findings are reported from the third phase of a small exploratory study that aimed to understand how pre-service teachers from culturally and linguistically diverse (CALD) backgrounds, and those who supervise them in early childhood settings, experience practicum assessment, and the extent to which practicum assessment takes into account pre-service teacher diversity. Discourse analysis (Foucault, 1972), applied to interviews with pre-service teachers and supervising teachers, revealed a persistent 'discourse of denial' of cultural difference on the part of supervising teachers, who nevertheless genuinely attempted to negotiate the inevitable challenges posed by the supervision of CALD pre-service teachers. The paper concludes that supervising teachers were at pains to produce and perpetuate a liberal humanist discourse within which all human beings are 'the same' or should be equal, even as they attempted to recognise CALD pre-service teachers' learning styles and needs.

- Description: There is an increasing concern that the current management practices for many coastal regions are unsustainable. Very few countries have planned to deal with the exacerbation of environmental decline in the face of sea level rise. It is therefore necessary to assess socioeconomic and environmental impacts of sea level rises to better understand the vulnerability of coastal zones, as part of devising adaptive and integrated management principles. This paper presents a systematic approach by which relevant stakeholders can be actively engaged in prioritising flood impact issues and deriving information for quantification of impacts for adaptation measures and demonstrates the approach through implementation in the Gippsland coastal region. As outcomes of the project, we have identified key issues of concern for this region for flood impacts and constructed synthetic response functions for quantification of impacts of floods on some of the key issues in the region. The analysis also showed that stakeholders consider that some of the issues are not likely to be significantly affected by floods and thus may not require adaptation measures. The analysis did not provide high agreement on some issues. Different approaches are required to assess the importance of these issues and to establish impact response functions for them.
