The Liverpool Interview Protocol (LIP) is a brief memory facilitation procedure designed for use in forensic investigative interviews. However, as the LIP techniques were derived from hypnotic investigative interviewing techniques, concern has been expressed by some senior police officers about a possible negative association with hypnosis. The aim of the present study was to address this concern by investigating not only the accuracy of the LIP in facilitating memory but whether witnesses receiving the LIP judged themselves, and observers judged the witnesses, to be hypnotized using the Long Stanford Scale of Hypnotic Depth. The results showed that the LIP increased correct memory for details of a crime incident, without increasing errors or inflating confidence, whilst being no more associated by witnesses or observers with the label of ‘hypnosis’ than a standard interview or a rapport condition. It is concluded that a negative association with hypnosis does not appear to be a particular issue with the LIP. It is also noted that the Cognitive Interview has yet to receive similar scrutiny.
