Witnesses and victims typically provide the central leads in police investigations, yet statistics from past research indicates in many instances these individuals are intoxicated.
To date, however, no research has looked at how best to interview such witnesses to maximise the amount of accurate information they recall.
In the present research, whilst on a night out, participants watched a videoed theft whilst either sober or moderately (MBAC = 0.05%) or severely (MBAC = 0.14%) intoxicated. A week later, in a different location, participants were interviewed using either the Enhanced Cognitive (ECI) or Structured Interview.
The ECI was found to improve the recall accuracy and completeness of witness accounts across all three drinking conditions. However, no significant interaction was indicated between alcohol and interview condition.
The study findings are discussed in terms of their real-world value in aiding police officers to elicit as complete and as accurate an account as possible from intoxicated witnesses.
目击者和受害者通常是警方调查的主要线索，但过去研究的统计数据表明，在许多情况下，这些人都处于醉酒状态。
然而，迄今为止，尚无研究探讨如何最好地采访这些证人，以最大限度地提高他们回忆的准确信息量。
在本研究中，参与者在外出时观看了一段录下的盗窃视频，参与者或清醒或适度（MBAC=0.05%）或严重（MBAC=0.14%）醉酒。一周后，在不同的地点，参与者分别使用增强认知（ECI）或结构化访谈进行采访。
研究发现，在所有三种饮酒条件下，ECI 都能提高证人证词的回忆准确性和完整性。然而，酒精和访谈条件之间没有显示出显著的相互作用。
研究结果讨论了在帮助警察从醉酒的证人那里获取尽可能完整和准确的陈述方面的实际价值。
