The efficacy of the Self‐Administered Interview: A systematic review

Obtaining accurate information from eyewitnesses is a crucial element in criminal investigations. Interview strategies such as the Cognitive Interview (CI) and the Self‐Administered Interview (SAI) have been developed and implemented to minimise inaccuracies and enhance the recall and reliability of eyewitness evidence. The SAI is a recent development within forensic psychology. However, a question remains as to the effectiveness of the SAI as an investigative interview tool. A systematic review of published studies employing the SAI was conducted (n = 22), and all were considered in relation to three variables (estimator, system and methodological). As the number of studies within the evidence base was relatively small, we could not ascertain whether the SAI is an effective investigative interviewing tool. However, the results demonstrate a number of positive benefits of the SAI. We discuss the implications of these findings for policy and directions for future research.
