Risk and protective factors for secondary traumatic stress and burnout among home visitors

ABSTRACT

The overarching goal of this study was to understand the context of home visitor secondary traumatic stress and burnout, and how this might affect intention to quit among home visitors, particularly focusing on potential risk factors and supportive strategies identified by the home visitors. All home visitors providing services in the state in which the research was conducted (N = 27) completed a structured interview and a quantitative survey at two time points, 6 months apart. Results indicated that more than two-thirds of the home visitors experienced either medium or high levels of secondary traumatic stress and burnout over the course of the study. Approximately one quarter of home visitors indicated thinking of leaving their present positio. Qualitative data indicated that risk factors associated with burnout included those related to both direct and non-direct services. Risk factors associated with secondary traumatic stress included traumatic stress of families, inability to recognize one’s own experiences of secondary traumatic stress, and unhealthy work culture. In terms of protective factors, home visitors strongly emphasized the importance of having a supportive supervisor who they could trust and communicate with openly.     

Adjusting for Change of Status in International Migration: Demographic Implications

The calculation of net immigration for the purpose of estimating the resident population in Australia is based on net permanent and long–term (12 months or more) movements into and out of the country. All international movements with duration of stay in Australia or travel abroad of less than 12 months (defined as short–term) are excluded. However, changes between short–term and long–term/permanent status can occur when people extend or shorten their stay or travel. Because net immigration is a significant component of Australia’s population growth (accounting for 40–50 per cent of annual growth), adjusting for these changes in migration status is thought to result in better estimates of net immigration and the resident population. The paper shows that adjusting for change of status can have a large impact on net immigration, particularly when the immigrant intake is small. Failure to adequately adjust for change of status can also lead to misleading conclusions about the relative contributions of net temporary and permanent movements to total net immigration. The effect on the resident population, however, is relatively small, being less than 1 per cent of the total population. The paper also addresses the question of how important it is for countries to adjust for change of migrant status in international migration statistics in the context of increasing international mobility.     

Attitudes of high school students and teachers towards Muslims and Islam in a southeastern Australian community

This study investigated attitudes of Australian high school students and teachers towards Muslims and Islam in two suburban high schools in the Logan/Brisbane area of southeastern Australia. Subjects (N = 156) responded to a questionnaire consisting of 24 survey items. Frequency, percentage distribution, and content analysis were performed. It was found that, generally, more respondents disagree with the negative stereotypes of Muslims as the media tend to present them. A majority of the respondents demonstrated positive attitudes towards Muslims and Islam, and strongly support the idea of multicultural coexistence in Australia. Recommendations are given in light of the research findings.     

Mixture modelling of recurrent event times with long-term survivors: Analysis of Hutterite birth intervals

We propose a mixture model that combines a discrete-time survival model for analyzing the correlated times between recurrent events, e.g. births, with a logistic regression model for the probability of never experiencing the event of interest, i.e., being a long-term survivor. The proposed survival model incorporates both observed and unobserved heterogeneity in the probability of experiencing the event of interest. We use Gibbs sampling for the fitting of such mixture models, which leads to a computationally intensive solution to the problem of fitting survival models for multiple event time data with long-term survivors. We illustrate our Bayesian approach through an analysis of Hutterite birth histories.     

Potential Airborne Asbestos Exposure and Risk Associated with the Historical Use of Cosmetic Talcum Powder Products

Over time, concerns have been raised regarding the potential for human exposure and risk from asbestos in cosmetic‐talc–containing consumer products. In 1985, the U.S. Food and Drug Administration (FDA) conducted a risk assessment evaluating the potential inhalation asbestos exposure associated with the cosmetic talc consumer use scenario of powdering an infant during diapering, and found that risks were below levels associated with background asbestos exposures and risk. However, given the scope and age of the FDA's assessment, it was unknown whether the agency's conclusions remained relevant to current risk assessment practices, talc application scenarios, and exposure data. This analysis updates the previous FDA assessment by incorporating the current published exposure literature associated with consumer use of talcum powder and using the current U.S. Environmental Protection Agency's (EPA) nonoccupational asbestos risk assessment approach to estimate potential cumulative asbestos exposure and risk for four use scenarios: (1) infant exposure during diapering; (2) adult exposure from infant diapering; (3) adult exposure from face powdering; and (4) adult exposure from body powdering. The estimated range of cumulative asbestos exposure potential for all scenarios (assuming an asbestos content of 0.1%) ranged from 0.0000021 to 0.0096 f/cc‐yr and resulted in risk estimates that were within or below EPA's acceptable target risk levels. Consistent with the original FDA findings, exposure and corresponding health risk in this range were orders of magnitude below upper‐bound estimates of cumulative asbestos exposure and risk at ambient levels, which have not been associated with increased incidence of asbestos‐related disease.     

An inconvenient truth: why evidence-based policies on obesity are failing Māori,Pasifika and the Anglo working class

Public health initiatives around obesity have generally worked well for middle class Australians and New Zealanders. This message has not had the same impact in Anglo working class areas and certain CALD communities, especially Māori and Pasifika, where obesity rates remain highest. This paper employs qualitative data from interviews with eighty-five Māori and Pasifika migrants to Australia to explore attitudes to food purchasing and consumption behaviours and associated health risks. It is evident the individual, medicalised approach to improving obesity rates has not been effective and there needs to be a new culturally responsive structural approach. This would require governments to prioritise population health over existing relationships with commercial food manufacturers – especially in relation to spatial domination of commercialised fast food outlets in low socio-economic status districts and in the areas of sports and education sponsorship. We also explore the assumptions of evidence-based health policy more generally, providing a critique of who is represented and served by the commercial solicitation and management of health research. This includes what constitutes ‘evidence’, who is conducting and funding the research, who appraises and compares the data and how is it interpreted and employed.     

Homosexual identity formation as a developmental process

Homosexual identity is conceptualized as a life-spanning developmental process that eventually leads to personal acceptance of a positive gay self-image and a coherent personal identity. Habermas' theory of ego development is utilized to provide a synthesis and understanding of the literature on the construction and maintenance of the homosexual identity. It is concluded that the homosexual identity generally emerges in a three-stage process in which the person progresses from: (1) an egocentric interpretation of homoerotic feelings to (2) an internalization of the normative, conventional assumptions about homosexuality to (3) a post-conventional phase in which societal norms are critically evaluated and the positive gay identity is achieved and managed. Developmental tasks associated with each stage are outlined in terms of their ego-integrative functions. Although the stages in the process of homosexual identity formation are theoretically the same for females and males, because of the paucity of research on the homosexual identity in females, this paper deals chiefly with males.
