The Enhanced Cognitive Interview: Theory, research and implementation

Abstract

Interviewing witnesses is a fundamental procedure during police investigations and forensic evaluations. However, professionals” knowledge, training and experience to interview witnesses is often scant, leading to the use of improper interview techniques and  the obtaining of limited and unreliable information. In this paper we address the Enhanced Cognitive Interview, currently accepted as one of the most effective methods to obtain good accounts. We fully describe this interview, the theoretical principles that justify its use, and the relevant research. Lastly, we have developed a Portuguese guide for using this interview, based on research and on the interviewing approach used by police forces in England and Wales (i.e. “PEACE”). Since no other protocol for the implementation of the Enhanced Cognitive Interview has been published in Portuguese, we consider reading this article a first step for all professionals that wish to use this style of interviewing.
