The Self-Administered interview, or SAI, is a powerful investigative tool that can be used to elicit comprehensive initial statements from witnesses, quickly and efficiently. It takes the form of a standardised protocol of clear instructions and questions that enable witnesses to provide their own detailed account, and is therefore ideal for use when restricted resources mean that a traditional interview is not possible.

Scientific tests of the SAI have shown that it elicits significantly more accurate and detailed information than a free-recall request. Completing an SAI also strengthens witness memory, meaning that witnesses are protected against forgetting, and against exposure to potentially distorting post-event information.

The SAI can add value to any incident investigation, from police or medical incidents, to industrial accidents and insurance investigations. Live trials with police forces have proven the SAI can facilitate an investigation by obtaining critical information quickly and effectively.

The SAI is an extremely effective investigative tool that protects witness memory, elicits critical information effectively and permits the timely prioritisation of witnesses – particularly in situations where limited resources are available to investigators

SAW-IT (Self-Administered Witness – Interview Tool) is a bespoke version of the SAI specifically developed for industrial/organisational settings.

A significant problem for many investigations is the delay incurred between employees witnessing or being involved in an accident or incident, and providing a statement. The quality of information obtained about an event is time-critical, not only because memory is prone to rapid decay but also because memory is fallible, and vulnerable to the influence of post-event information SAW-IT is a specially tailored version of the SAI which incorporates appropriate cues to facilitate the remembering and reporting of incident-relevant information, including information about contributory and/or causal factors, etc. Given the importance of accident and incident data in determining safety policy and procedure, it is, in our view, of vital importance to obtain high-quality information in an investigation, using purpose-based investigatory tools such as the tailored SAW-IT.
