Background

The prevalence of fear of birth has been estimated between 8–30%, but there is considerable heterogeneity in research design, definitions, measurement tools used and populations. There are some inconclusive findings about the stability of childbirth fear.

Aim

to assess the prevalence and characteristics of women presenting with scores ≥60 on FOBS-The Fear of Birth Scale, in mid and late pregnancy, and to study change in fear of birth and associated factors.

Methods

A prospective longitudinal cohort study of a one-year cohort of 1212 pregnant women from a northern part of Sweden, recruited in mid pregnancy and followed up in late pregnancy. Fear of birth was assessed using FOBS-The fear of birth scale, with the cut off at ≥60.

Findings

The prevalence of fear of birth was 22% in mid pregnancy and 19% in late pregnancy, a statistically significant decrease. Different patterns were found where some women presented with increased fear and some with decreased fear. The women who experienced more fear or less fear later in pregnancy could not be differentiated by background factors.

Conclusions

More research is needed to explore factors important to reduce fear of childbirth and the optimal time to measure it.  相似文献

Drawing upon findings from a national evaluation of student social workers' experiences of ‘non-traditional’ placements with a national charity, this article considers what such placements can contribute to the development of an individual and collective sense of professional identity for social work. This is explored against the background of current developments in social work education in England, including changes to the requirements for practice placements and the introduction of ‘fast-track’ routes to qualification, preparing students for social work in statutory children's services. The article suggests that with the establishment of The College of Social Work and the development of the Professional Capabilities Framework, relevant to all social workers throughout their careers, the profession has an opportunity to promote a concept of social work in England beyond that required by statutory sector employers; and that practice learning in non-statutory and non-traditional settings has an important role to play in this.  相似文献

An exploratory teaching approach was inspired by the communicative experiences of d/Deaf students in tertiary education. ‘Theory of Mind’ has been used by some to describe the capacity to appreciate that views of others may be different from our own, a concept that could provide a different way for students and educators to understand the barriers identified. An adapted assessment highlighted challenges faced and a communication group provided opportunities for extending personal understandings of social settings. Emerging ideas to inform practice and potential implications for inclusion have relevance for other contexts.  相似文献

Recent rapid economic growth in Ireland has been accompanied by a strong surge in the number of women in employment, and this has led to a significant increase in the proportion of dual‐earner families. These changes have brought the issue of reconciliation between work and care commitments to the fore. Flexible working arrangements in firms have been identified as one important means of balancing work and other commitments. In this article we investigate the relationship between four flexible working arrangements; flexitime, part‐time hours, working from home and job sharing, and two key employee outcomes; work pressure and work–life conflict, using data from the first national survey of employees in Ireland in 2003. Our results show that while part‐time work and flexitime tend to reduce work pressure and work–life conflict, working from home is associated with greater levels of both work pressure and work–life conflict. We conclude that it is important to distinguish between flexible working arrangements to discover their potential for reducing work pressure and work–life conflict.  相似文献

A three-parameter F approximation to the distribution of a positive linear combination of central chi-squared variables is described. It is about as easy to implement as the Satterthwaite-Welsh and Hall-Buckley-Eagleson approximations. Some reassuring properties of the F approximation are derived, and numerical results are presented. The numerical results indicate that the new approximation is superior to the Satterthwaite approximation and, for some purposes, better than the Hall-Buckley-Eagleson approximation. It is not quite as good as the Gamma-Weibull approximation due to Solomon and Stephens, but is easier to implement because iterative methods are not required.  相似文献

Major natural disasters in recent years have had high human and economic costs, and triggered record high postdisaster relief from governments and international donors. Given the current economic situation worldwide, selecting the most effective disaster risk reduction (DRR) measures is critical. This is especially the case for low‐ and middle‐income countries, which have suffered disproportionally more economic and human losses from disasters. This article discusses a methodology that makes use of advanced probabilistic catastrophe models to estimate benefits of DRR measures. We apply such newly developed models to generate estimates for hurricane risk on residential structures on the island of St. Lucia, and earthquake risk on residential structures in Istanbul, Turkey, as two illustrative case studies. The costs and economic benefits for selected risk reduction measures are estimated taking account of hazard, exposure, and vulnerability. We conclude by emphasizing the advantages and challenges of catastrophe model‐based cost‐benefit analyses for DRR in developing countries.  相似文献
