BackgroundPerinatal distress has largely been conceptualised as the experience of depression and/or anxiety. Recent research has shown that the affective state of stress is also present during the perinatal period and thus may add to a broader understanding of perinatal distress.AimThe aims of the present study were to investigate the changes in depression, anxiety and stress symptoms across pregnancy, and to explore the prospective relationships between these symptoms.MethodsTwo-hundred and fourteen pregnant women were recruited when they were less than 16 weeks gestation. Women completed depression, anxiety and stress measures on a monthly basis, from 16 weeks gestation through to 36 weeks gestation. The covariate measures of sleep quality and social support were assessed bi-monthly at 16, 24 and 32 weeks gestation.FindingsLevels of depression, anxiety and stress symptoms were all shown to change over time, with women experiencing fewer symptoms during the middle of their pregnancy. Higher symptoms early in pregnancy predicted higher symptom levels throughout the rest of pregnancy. Higher depression scores early in pregnancy were also shown to predict higher anxiety and higher stress scores in late pregnancy. Increased stress scores during mid pregnancy also predicted higher anxiety scores in late pregnancy.ConclusionCurrent findings indicate that symptom levels of depression, anxiety and stress vary over the course of pregnancy. Increased depression in early pregnancy seemed to be particularly pertinent as it not only predicted later depression symptoms, but also increased anxiety and stress in late pregnancy. Collectively, these results further highlight the importance of emotional health screening early in pregnancy.  相似文献

BackgroundA substantial body of research has focused on maternal perinatal mood and wellbeing, with the focus predominantly being on depression, and to a lesser extent, anxiety. Perinatal maternal stress has also been investigated recently, but to a far lesser extent. The present paper questions whether the term ‘perinatal distress’ accurately captures the range of challenges experienced by women during the perinatal period, when the scope of ‘distress’ is limited to the experience of depression and anxiety alone.MethodA review of the perinatal literature was conducted using several databases, to identify studies that have focused on the experience of stress as a distinct affective state in the perinatal period.FindingsThe findings of two recent studies which have employed a broader conceptualisation of perinatal distress to encompass the experience of stress as well as depression and anxiety are outlined. These recent studies have identified the experience of stress both in conjunction with and independent of depression and anxiety.ConclusionIt is argued that future studies should investigate the concept of stress as a separate affective state throughout the perinatal period, in order to further assess how it differs from depression and/or anxiety. A more comprehensive understanding of women's experiences during their transition to motherhood, and whether ‘stress’ plays a critical role in the development and maintenance of perinatal anxiety and/or depression is needed.  相似文献

Animals are increasingly acknowledged as historical agents. There are calls for more critical approaches that explore how this agency—often shared with humans—is embedded within wider relations of power. This paper responds by employing Critical Theory, particularly the ideas of Jurgen Habermas, to explore how interspecies agency is shaped and constrained by its broader socioeconomic context. Empirical illustrations are drawn from the experiences of Dales ponies and people in the early twentieth century, who found themselves navigating the growing commodification of their shared lifeworld. The findings suggest the outcome of this process of “colonisation” was not inevitable. Rather, just as the demise of the ponies seemed unstoppable, their shared communicative relations re-emerged powerfully during the harsh winter of 1947. The paper asks what this means for our understanding of the apparently irrevocable decline of horsepower and how we might better understand horses’ own experiences of such events and processes.  相似文献

Social, academic, emotional functioning and social support of 99 ninth-grade Asian American students were investigated using standardized measures. When compared to 404 ninth-grade Caucasian adolescents who had attended the same school, Asian American students exhibited less delinquent behavior and performed better academically. However, they were significantly more isolated, more depressed and anxious, less apt to be involved in after school activities or seek help for their problems, and internalized their social problems. Also, they had fewer role models and less social support, underscoring the psychosocial and emotional plight of Asian American adolescents and the dire need to establish proactive outreach programs.This work was supported by NIMH grant #MH41569-07.  相似文献

This paper describes the evaluation of a three year Initiative run by the YMCA. The aim of the Initiative was to set up 30 different projects in YMCA centres in England, to provide help and support to the parents of teenagers. The Initiative was evaluated by the Trust for the Study of Adolescence. Funding was agreed for 29 projects, which included group‐based courses, ‘Dads and Lads’ projects, mediation schemes, transition evenings, and families and computing courses. A variety of outcomes from these projects are identified, both for parents, young people, project workers, and the YMCA as an organisation. Key issues and learning points from the Initiative are also identified. Finally, some general comments are made about strategies to provide support to the parents of teenagers.
