Abstract

Background

Interviewer training using automated avatars and interventions has emerged as a potentially scalable approach to improving questioning skills in child sexual abuse interviews. Although behavioral modeling has been proven to be an effective part of this training, the efficacy of its individual components remains unexplored.

Objective

We aimed to demonstrate the scalability of an interviewer training approach using AI-driven avatars and to examine the effectiveness of different components of modeling in improving the use of open questions.

Participants and setting

1168 lay participants recruited via crowdsourcing platforms were randomly assigned to 28 conditions varying the combination of modeling components.

Methods

Each participant conducted one simulated child sexual abuse interview online after receiving one combination of the modeling components. The modeling components consisted of reading learning points regarding good and bad interview approaches, watching example videos of good and bad interviews, and reading the case outcomes (i.e. what had happened to the avatars interviewed in the example videos).

Results

Correlation and regression analyses found positive impact of videos showing good interview practices on the quality of the participants' subsequent interviews while little effect was found of the learning points and the case outcomes. Surprisingly, we found a negative impact of videos showing bad interview practices on the quality of the participants’ interviews.

Conclusions

The results demonstrated the scalability of interviewer training using automated avatars and the effectiveness of some modeling components in improving interviewer behavior. Overall, interviewers tended to follow the modeled behaviors regardless of whether these were positive or negative which resulted in improved interview skills through positive models but detrimental effects after negative models. However, the negative impact of bad modeling in the reproduction of learned behaviors in interview simulations should still be investigated in the context of transfer.
日本儿童性虐待访谈的可扩展培训:使用人工智能驱动的化身来测试多种行为建模干预
使用自动化身和干预的采访者培训已经成为一种潜在的可扩展方法,可以提高儿童性虐待访谈中的提问技巧。虽然行为建模已被证明是这种训练的有效部分,但其个别组成部分的功效仍未被探索。目的:我们旨在展示使用人工智能驱动的化身的采访者培训方法的可扩展性,并检查建模的不同组件在改进开放式问题使用方面的有效性。参与者和通过众包平台招募的1168名非专业参与者被随机分配到28个不同建模组件组合的条件下。方法每位参与者在收到一个建模组件组合后,进行一次在线模拟儿童性虐待访谈。建模组件包括阅读关于好的和坏的面试方法的学习点,观看好的和坏的面试示例视频,以及阅读案例结果(即在示例视频中采访的化身发生了什么)。结果相关分析和回归分析发现,展示良好访谈实践的视频对参与者后续访谈的质量有积极影响,而对学习点和案例结果的影响不大。令人惊讶的是,我们发现展示不良面试做法的视频对参与者的面试质量有负面影响。结论采用自动化虚拟形象对面试官进行培训具有可扩展性,部分建模组件在改善面试官行为方面具有有效性。总的来说,面试官倾向于遵循模范行为,无论这些行为是积极的还是消极的,这导致了通过积极模式提高面试技巧,但消极模式后的不利影响。然而,在迁移的背景下,不良建模对面试模拟中习得行为再现的负面影响仍有待进一步研究。
