It is now an important part of nursing to actively participate in research and evidence based practice in order to continually improve the standard of the health care system. This process ensures that nurses are kept up to date with relevant information needed to provide the most effective care for patients. In this essay I will base my research within the realms of mental health nursing which is my area of professional practice. Furthermore I will explain some of the key issues surrounding reliability, validity and trustworthiness, all terms of which will be defined. I will then relate these issues to how they are applied in mental health nursing practice by referring to existing research.
In order to fully explore the findings of the research I will use studies from both a qualitative and quantitative perspective. The European Commission states that ‘qualitative studies investigate in-depth the motivations, the feelings, the reactions of selected social groups towards a given subject or concept, by listening and analysing their way of expressing themselves in discussion groups or with non-directive interviews.’ This is largely different to information that is obtained in a quantitative study.
