Google Search deploys a "Onebox" feature at the top of the results page when users conduct searches for Child Sexual Abuse Material. This study evaluates the impact of a strategic shift in this feature, comparing a revised intervention, focused on repercussions and therapeutic resources, to a previous iteration that focused on reporting. Using a difference-in-differences analysis of internal Google Search logs data, we found the new messaging resulted in a 3.8 percentage point reduction as compared to the status quo in subsequent CSAM-related queries within the same Search session. We found an average click through rate of 0.73% on any of the hyperlinked buttons to help-providing resources. Together, this research presents convergent evidence that a subset of individuals can be deterred from ongoing CSAM-seeking and redirected to therapeutic services.

翻译：谷歌搜索在用户搜索儿童性虐待材料时，会在结果页面顶部部署"Onebox"功能。本研究评估了该功能战略变更的影响，将聚焦于后果警示与治疗资源的修订版干预措施，与之前侧重于举报功能的旧版方案进行比较。通过运用双重差分法分析谷歌内部搜索日志数据，我们发现新信息推送使同一搜索会话中后续与儿童性虐待材料相关的查询量较基准状态降低了3.8个百分点。同时，帮助资源链接按钮的平均点击率达到0.73%。综合来看，本项研究提供了聚合性证据，表明部分个体能够被劝阻继续搜寻儿童性虐待材料，并转向寻求治疗服务。
