Chapter outline Having identified the meaning of research in the previous chapter, we look now at the related concept of evidence-based practice. We will see that. although research may provide the best form of evidence (the best form of knowledge), there are other forms of evidence that are often used to support practice. This chapter will also look at some of the ways in which people sometimes avoid using evidence. The acquisition of evidence, through research or other means, must be carried out within the established principles of ethical conduct. This chapter will look at what this means for the researcher and for you, as you begin to make sense of a career within an ethical and evidence-based profession.
