Abstract
This chapter presents an explanation of the use of a synchronous text-based online interviewing method, which is a method of interviewing participants online using an instant messaging service to type to each other at the same time in a conversational style. This method was originally designed to address the need to carry out interviews on a potentially sensitive subject while also achieving a continuity of private discussion. It is particularly useful for situations in which face-to-face or telephone interviews are inappropriate. Online text-based interviews can, therefore, act as a solution to a perennial concern in health-related research, and is an advance on the standard practices of open-ended questionnaires, email interviews, and online discussion boards. Synchronous text-based online interviewing can be offered as an additional choice to research participants, as well as used on its own if examining sensitive topics or if additional anonymity is suitable. The use of the method alongside its strengths and weaknesses will be outlined and discussed in this chapter.
