Chronic fatigue syndrome (CFS) is a controversial condition defined by 6 months or more of unexplained fatigue, and at least four out of eight cognitive and physical symptoms. Over the past 2 decades, CFS has been the subject of significant debate regarding its definition, cause and recommended treatment. Because a cure for the syndrome has not yet been located, efforts to improve functioning and overall quality of life through rehabilitation represent the most practised form of treatment to date. However, controversy remains as to which approach to rehabilitation is most effective for individuals with CFS. Interventions which take place within real‐world environments and utilise community‐based organizations such as centres for independent living offer a newly explored means of support and rehabilitation. The present paper reviews a variety of approaches to rehabilitation for individuals with CFS, describing their applications with different types of patients, and providing critical commentary on the research methodologies used to evaluate them. Innovative community‐based rehabilitation programmes and their outcomes are described as an alternative with some promise that may compliment more traditional approaches.  相似文献

This paper describes and discusses issues concerned with therole of the nurse in health promotion work. It represents thefirst phase of a research project designed to explore this role,and presents the evolving philosophical framework for the study.The study is taking place currently in the United Kingdom andhas been made possible by the (first) award of a Post DoctoralNursing Research Fellowship to the project director. Against the backdrop of the World Health Organization's ‘Healthfor All by the year 2000’ (WHO HFA 2000) movement therehave been repeated calls for nurses to be the leaders in healthpromotion. Policy makers and educators have responded to thesecalls by claiming a central role for nursing and putting healthpromotion high on policy and training agendas. Very little attention,however, has been devoted to exploring the legitimacy and developmentof this role in nursing. Generally, nurses seem enthusiasticabout health promotion, and sure that they have a role to play.What is less certain is what this role is. The study seeks toclarify this by exploring policy, behaviour, and attitudes.Policy provides the framework for practice, and operates ata number of levels. In this early paper we review the literatureto explore policy and practice from international to grassrootslevels. We also make some initial observation derived from ourpilot work.  相似文献

The originator of LETTERLAND describes a unique teaching model which blends a structured phonics approach with whole language teaching. Children are introduced to a language about language which enables them to acquire a confident mastery of print based on parallel learning. Its pictogrammatic approach creates a stimulus to inquiry and a learning environment which is imaginative and friendly.  相似文献

渐进式责任制护理是据国情产生的一个新生事物。其特征是全员参与,在完成功能制工作之后,每位护士负责一位重危病人的护理。其护理内容完全按照责任制护理进行。其不足之处是人员素质的差异,使责任制护理质量有别。不过,可随着条件的成熟,不断得到改进。  相似文献

Debate about the best paradigm for mental health nursing is compounded by threats from mainstreaming and genericism. In nursing education, integrated practice may have been devalued in a matrix of reductionist disciplines. The 'gendered' nature of professional knowledge may create a schismatic and self-defeating attitude in nurses. Conversely, nurses may be exhorted to adopt a 'male' paradigm in order to gain academic credibility, in which the caring dimension may be lost. Other polarities such as ideological distinctions between treatment in hospital and care in the community lead to conceptual confusion. These schisms in care are detrimental to both professionals and users. The writers argue that these tensions may be addressed in an 'androgenous' model which presents a challenge to both value systems, rejects the dominance of schismatic models, and offers the potential for a new professional integrity.  相似文献

Abstract We investigated factors correlated with abnormal behavior in the elderly residing in a special nursing home (group A) and a psychiatric hospital (group B) using the dementia behavior disturbance scale, the mini mental state examination, the Japanese version of the Philadelphia Geriatric Center morale scale, and the ADL assessment scale. The cognitive function of group B was decreased compared with that of group A, but most activities of daily living (ADL) in the latter group were disrupted compared with those in the former. Only a few categories of ADL correlated with abnormal behavior in group A, whereas cognitive function, quality of life, and most categories of ADL correlated with abnormal behavior in group B. These results suggest that factors correlated with abnormal behavior in the elderly differ within institutions of medical and social welfare systems.  相似文献

Critics of Kohlberg's moral theory today focus on the content of his theory and more specifically on its justice-orientated moral concept. This has led to the well-known 'justice-care debate'. The purpose of this article is to critically examine the validity of Kohlberg's moral theory for research in nursing ethics from a caring perspective (referring to the content) as well as from a cognitive-structural perspective (referring to the basic assumptions of the model). The analysis points to the usefulness and value of the cognitive-structural model to empirically study nurses' ethical behaviour; the content of Kohlberg's model, however, needs to be adapted by adding a caring perspective as well as some personal and situational variables. An adjusted version of Kohlberg's model is proposed and discussed.  相似文献

Men with prostate cancer ( n = 11) were interviewed during an in-patient period at a urological clinic, about their experiences of met and unmet needs from health professionals. Their perception of quality of life and sense of coherence were also assessed. The findings were analysed from a phenemenological-hermeneutic perspective and interpreted within the concept of transition. It was interpreted that objective functional health needs were mostly met by health professionals and subjective existential needs were mostly not met. The analysis revealed patients as passive or active receivers of care. Passive receivers were explicitly and implicitly stating unmet needs, or explicitly stating satisfaction with nursing care at the same time as implicitly contradicting, referring to their needs as bagatelles, unimportant, whereas active receivers talked about their needs explicitly with the staff and did not state implicit unmet needs. This suggests that nurses need to be aware of and have sensitive ears to undertones in statements and actively seek for patients' needs. The most important nursing care areas seemed to be to provide solutions to physical problems together with staff support including information, and acting to increase confidence in staff and staff availability. This encourages patients, wives and families, in co-operation, towards a healthy exit of transition.  相似文献
