Abstract: The Self-Administered Interview (SAI(c)) is a booklet in which
eyewitnesses write down their memories of an incident without assistance.
The SAI can gather a significant amount of eyewitness information, and
completing the SAI soon after witnessing an event can improve later recall.
This study aimed to reveal the factor of effectiveness of the SAI and
specifically focused on the method of handwriting. Participants watched a
video and immediately recalled the event in the three conditions:
SAI-writing, SAI-speaking, and free recall (speaking). One week later,
participants again recalled the event via free recall. The results showed
that participants in the SAI-writing condition reported more correct
information than those in the other conditions at both time points. This
suggests that a factor of effectiveness of the SAI is the method of writing.
Thus, initial written recall using the SAI could facilitate later recall in
police investigative interviews.
