The value of single-case research.
This paper presents an argument in support of clinic based research. The role that the clinic-based speech and language therapist has in advancing our knowledge of communication disorders and their treatment is emphasised. The value of single-case research within the field of speech and language therapy is discussed and the arguments are presented with respect to stammering. A single case study of pre-school dysfluency is used to illustrate the potential for conducting research using this methodology in a clinical environment.
