The present study aimed to test the effectiveness of giving feedback on simulated avatar interview training (Avatar Training) across different experiments and participant groups and to explore the effect of professional training and parenting experience by conducting a mega-analysis of previous studies. A total of 2,208 interviews containing 39,950 recommended and 36,622 non-recommended questions from 394 participants including European and Japanese students, psychologists, and police officers from nine studies were included in the mega-analysis. Experimental conditions were dummy-coded, and all dependent variables were coded in the same way as in the previously published studies. Professional experience and parenting experience were coded as dichotomous variables and used in moderation analyses. Linear mixed effects analyses demonstrated robust effects of feedback on increasing recommended questions and decreasing non-recommended questions, improving quality of details elicited from the avatar, and reaching a correct conclusion regarding the suspected abuse. Round-wise comparisons in the interviews involving feedback showed a continued increase of recommended questions and a continued decrease of non-recommended questions. Those with (vs. without) professional and parenting experience improved faster in the feedback group. These findings provide strong support for the efficacy of Avatar Training.

本研究旨在通过对以往研究的大规模分析，测试不同实验和参与者群体对模拟化身面试培训（Avatar Training）提供反馈的有效性，并探索专业培训和育儿经验的效果。共有 2,208 次访谈，包含来自 9 项研究的 394 名参与者（包括欧洲和日本学生、心理学家和警察）的 39,950 个推荐问题和 36,622 个非推荐问题。实验条件是虚拟编码的，所有因变量的编码方式与先前发表的研究相同。专业经验和育儿经验被编码为二分变量并用于适度分析。线性混合效应分析表明，反馈对增加推荐问题和减少非推荐问题、提高从头像中获得的细节质量以及就疑似滥用得出正确结论具有强大的影响。涉及反馈的访谈中的全面比较显示推荐问题持续增加，非推荐问题持续减少。那些有（与没有）专业和育儿经验的人在反馈组中进步得更快。这些发现为 Avatar Training 的有效性提供了强有力的支持。涉及反馈的访谈中的全面比较显示推荐问题持续增加，非推荐问题持续减少。那些有（与没有）专业和育儿经验的人在反馈组中进步得更快。这些发现为 Avatar Training 的有效性提供了强有力的支持。涉及反馈的访谈中的全面比较显示推荐问题持续增加，非推荐问题持续减少。那些有（与没有）专业和育儿经验的人在反馈组中进步得更快。这些发现为 Avatar Training 的有效性提供了强有力的支持。
