BACKGROUND: Resource constraints and the drive towards evidence-based practice are currently prompting the review of health visiting services, which are a costly element of community health services in the United Kingdom. There is a shortage of evidence about effective domiciliary health visiting practice that can inform local and national decisions about developing and reforming this service. AIMS: This paper is based on a study which aimed to articulate the health visiting expertise involved in recognizing and responding to client need during home visits. The paper describes the innovative, multi-method approach used to articulate this expertise, and presents the rationale for this unusual approach. DISCUSSION: The study used the complementary methods of a 20-minute simulated visit to an actress-client, a postsimulation focused interview and subsequent observation of actual home visits with 15 study participants. Data-gathering took place between 2001 and 2002. The rationale, strengths and limitations of the methodology are discussed, and recommendations made for further development based on the work. CONCLUSIONS: The findings confirmed the utility of this unusual combination of methods, with their blend of control and naturalism, for articulating the knowledge and expertise which underpins assessment practice. Further research using a similar approach is recommended for the systematic examination of professional expertise in nursing and multi-disciplinary contexts.  相似文献

The DNP is being touted as the answer to the faculty shortage. There is no evidence that DNP graduates are any more willing to embrace the low salaries of nursing faculty than PhD graduates. The idea of the DNP as the answer to the faculty shortage is challenged.  相似文献

BACKGROUND: Health visitors (HVs), also known as public health nurses, in the UK provide a universal community-based service to preschool children and their parents. Since they have ongoing supportive contact with almost all mothers and young children they have opportunities to identify problems in the parent-infant relationship: for example during developmental screening, home visits and immunisation clinics. Research into the role of screening for problems in the parent-child relationship in early childhood is sparse and little is known about how such problems are currently identified in the community. OBJECTIVE: To explore the approaches taken by health visitors (HVs) to identifying problems in the parent-child relationship. DESIGN: Focus group study. SETTING: Glasgow, Scotland. Participants: 24 health visitors sampled purposively. RESULTS: Multiple sources of information were used by health visitors in assessing parent-child relationships. These include use of known risk factors, knowledge of local norms, direct observations of behaviour, reflection on the relationship between the parent and health visitor, as well as more intuitive reactions. In many cases understanding difficulties in parent-child relationships involved piecing together a jigsaw over a considerable time span. Continuity of relationships appeared to be crucial in this task. Home visits were described as the most informative setting in which to develop an understanding of the parent-child relationship. Participants reported a lack of formal training in the assessment of parent-child relationships and were keen to obtain more training. CONCLUSIONS: Health visitors use complex strategies to integrate information about parent-child relationships. These strategies are acquired in a variety of ways, but receive little emphasis during basic professional training.  相似文献

Title. Application of a model of social information processing to nursing theory: how nurses respond to patients. Aim. This paper is a report of a study to assess the applicability of a theoretical model of social information processing in expanding a nursing theory addressing how nurses respond to patients. Background. Nursing communication affects patient outcomes such as anxiety, adherence to treatments and satisfaction with care. Orlando’s theory of nursing process describes nurses’ reactions to patients’ behaviour as generating a perception, thought and feeling in the nurse and then action by the nurse. A model of social information processing describes the sequential steps in the cognitive processes used to respond to social cues and may be useful in describing the nursing process. Methods. Cognitive interviews were conducted in 2006 with a convenience sample of 5 nurses in the United States of America. The data were interpreted using the Crick and Dodge model of social information processing. Findings. Themes arising from cognitive interviews validated concepts of the nursing theory and the constructs of the model of social information processing. The interviews revealed that the support of peers was an additional construct involved in the development of communication skills, creation of a database and enhancement of self‐efficacy. Conclusion. Models of social information processing enhance understanding of the process of how nurses respond to patients and further develop nursing theories further. In combination, the theories are useful in developing research into nurse–patient communication. Future research based on the expansion of nursing theory may identify effective and culturally appropriate nurse response patterns to specific patient interactions with implications for nursing care and patient outcomes.  相似文献

目的:描述孕妇配偶的压力水平及性格特征,探讨压力与性格特征的相关性。方法:对167例孕妇配偶用妊娠压力量表测量其压力水平,用艾森克个性问卷测量其性格特征,并分析性格特征对压力的影响。结果:压力量表测量赤示孕妇配偶的压力处于中等水平(M=1.53);艾森克个性问卷示孕妇配偶E因子(性格内外向)、P因子(精神病质)、N因子(神经质)及L因子(掩饰程度)均高于常模,具有性格内向,有精神病质和神经质双重倾向,与常模(n=1000)比较,差异有显著性意义(t=22.32~34.88,P均>0.05);孕妇配偶的压力水平与精神病质、性格内外向及神经质得分成正相关(r=0.196~0.347,P<0.05)。结论:孕妇配偶存在中等程度的压力,其不良性格特征会增加压力,提示临床护理工作者可以用艾森克个性问卷对孕妇配偶进行心理测试,对于有不良性格特征的孕妇配偶应给予重点关注。  相似文献
