The self-administered interview (SAI©) 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.

写作会增强回忆和记忆巩固吗？揭示自我管理面试的有效性因素

自我管理式访谈 (SAI©) 是一本小册子，目击者可以在其中写下他们对事件的回忆，无需帮助。SAI 可以收集大量目击者信息，在目击事件后尽快完成 SAI 可以提高以后的回忆。本研究旨在揭示 SAI 的有效性因素，并特别关注手写方法。参与者观看视频并在三种情况下立即回忆起事件：SAI 写作、SAI 说话和自由回忆（说话）。一周后，参与者通过自由回忆再次回忆起事件。结果表明，在两个时间点，SAI 书写条件下的参与者报告的信息比其他条件下的参与者更正确。这表明 SAI 有效性的一个因素是写作方法。
