Nursing literature

Abstract: A number of articles in the nursing literature discuss the differences between descriptive and interpretive approaches to doing phenomenology. A review of studies demonstrates, however, that many researchers do not articulate which approach guides the study, nor do they identify the philosophical assumptions on which the study is based. Such lack of clarity makes it difficult for the reader to obtain a sense of how the knowledge produced by the study is to be evaluated and used. In this article, the authors compare the philosophical components of descriptive and interpretive approaches to doing phenomenology and illustrate types of knowledge produced by each through reviewing specific studies. They focus on the various uses of phenomenology in generating useful knowledge for health care practice.

Abstract: Since its introduction as a research approach in the late 1940s the Delphi technique has had over 1000 published research utilizations. Most of these have been in the field of social policy. However, a review of contemporary nursing literature suggests that it is becoming a popular choice among nurse researchers. With its focus on maximizing participant's judgements and decision-making abilities the Delphi technique is a useful tool in the research armoury of a young profession. However, questions remain about its scientific respectability. This paper gives an overview of what the Delphi technique is, the criteria for selecting it as a research approach, the studies where it has been used and its advantages and disadvantages.

Abstract: Background. Observation is used in research in two ways – structured and unstructured. Which of these methods to choose depends on the research question but will be defined predominantly by the paradigm underlying each study. Positivistic research generally uses structured observation and interpretist/naturalistic paradigms use unstructured observation. This paper is concerned with unstructured observation. Aim. To discuss the importance of unstructured observation as a research method and to examine critically the problems associated with both access and field notes. Application to nursing. Although unstructured observation has been used in nursing research, it is less favoured than the interview. Furthermore, although some of the dilemmas concerned with observation such as the role of the researcher, covert research and informed consent have received attention in the nursing literature, other aspects remain relatively unexplored. In particular little has been written concerning access to the field and field notes. Both of these aspects have practical and theoretical considerations that require the attention of the researcher. This omission may partly explain nurses' apparent reluctance to use unstructured observation in their studies. This paper seeks to redress this situation.
