Investigative interviewing is the process of eliciting accurate and detailed information from a person about an event or situation, in order to facilitate decision-making. This presentation will provide an overview of what constitutes best-practice investigative interviewing, and how this can be achieved. It focuses on developing communication strategies which minimise miscommunication and error, and ensure that the interviewee feels heard and valued. The techniques discussed are applicable to a wide range of interviewees, including suspects, victims and witnesses. Finally, the presentation will cover considerations and strategies for interviewing vulnerable groups who have complex communication needs.
