What is Forensic Interviewing?

Forensic Interviewing is interviewing in any interview situation that is conducted in a legal setting, the purpose of which is to gain information or evidence to be used in a legal setting or as part of the criminal justice system, or is an interview that, although perhaps not its main purpose, has the future potential to be used as evidence in legal, disciplinary or other investigative scenarios.

It is labelled ‘Forensic Interviewing’ but it is also commonly referred to as ‘Investigative Interviewing’.

Who should use Forensic Interviewing techniques?

Anyone who conducts interviews in the course of their work for any purpose. Forensic Interviewing techniques are not the sole preserve of police officers or investigators; they can also be a useful addition to the interactional toolkit of anyone who conducts interviews in the non-police public sector and private sector e.g. Trading standards, NHS Protect, insurance companies’ fraud departments, HR managers etc.


Why should you use Forensic Interview techniques?

Forensic Interviewing techniques do not necessarily replace existing techniques; they can be used to enhance existing interview techniques and can provide a framework through which those who conduct interviews as described in ‘what is Forensic Interviewing’ can adhere to in order to enhance the credibility and quality of interactions as evidence, and enhance the investigative yield from their interactions with suspects/employees/witnesses/victims.

Forensic Interviewing provides a framework that sits above (and does not replace)  locally-held guidance and statutory regulations that interviewers across sectors may be bound by, and provides a higher standard that is chiefly concerned with ethical interviewing techniques and enhancing the evidentiary potential of the interview. Forensic Interviewing in the context of the Society means using techniques that enhance the investigative and evidentiary quality of interviews, whilst enhancing elements of interaction not necessarily immediately at the forefront of the interview remit – building and maintaining rapport with the interviewee.

Forensic Interviewing was adopted by the police service in the United Kingdom in the early 1990’s. Since then it’s use has been the subject of numerous and detailed research projects. Invariably it has been shown to produce a greater quantity of more accurate information than other methods. The inherently ethical nature of the techniques have also resulted in a marked decline in the number of challenges to ‘confession’ evidence that had plagued the police service in previous decades.

The proper use of these techniques should result in a more efficient, and therefore more cost effective investigation, with fewer challenges to the outcomes, and therefore less negative PR for the organisation.

What are the techniques used in Forensic Interviewing?

The techniques relate to the different methods used to obtain the information from the interviewee. Most often the interview will follow a framework known as PEACE,

Planning and preparation;
Engage and explain;

Forensic techniques are used during the Account phase and include Cognitive Interviewing, Enhanced Cognitive Interviewing and Conversation Management.

What do you mean by ‘evidence based and ethical practice’?

The interview techniques we support must be backed by verifiable academic research. Additionally, we believe that every person who is interviewed for a purpose that may have a detrimental effect on themselves or another has the right to be interviewed by a properly trained interviewer using ethical techniques. Specifically we  do not support techniques that aim to secure a confession, use rationalisation or minimisation/maximisation to encourage the interviewee to confess, or include any assumption of guilt. We do not support interrogation techniques or techniques that focus on detecting deception in an interviewee.

What are the standards that you support?

The minimum standards are based upon the guidance in the Association of Chief Police Officers (ACPO) Investigative Interviewing Strategy 2009, the PEACE model, the National Operating Standards held by Skills for Justice (CJ101 – CJ103, CJ201 – CJ203, CJ301), and the Home Office document, Achieving Best Evidence. The interview techniques are based on Cognitive Interviewing, Enhanced Cognitive Interviewing and Conversation Management.
