The use of the telephone interview for research

The increasing popularity of the telephone interview as a research method may be a reflection of broader social change and technological advances, with increased use and acceptability of telecommunications to support healthcare and service industries in general. Despite its widespread use there are few definitions of the term. Studies which directly compare telephone and face-to-face interviewing tend to conclude that telephone interviewing produces data which are at least comparable in quality to those attained by the face-to-face method. While it has been used for large survey studies, in nursing research the telephone interview is used predominantly in smaller-scale qualitative studies, where contact has already been made with the participants. The telephone interview was used in a study by one of the authors (EC) which explored the experience of postoperative pain. Issues relating to ethical considerations, reliability, validity, limitations and analysis are explored. The use of the approach for pain research is reflected upon before considering the wider applications that are available for this method of data collection in healthcare practice.
