Covert Human Intelligence Sources (CHIS) provide unique access to criminals and organised crime groups, and their collection of intelligence is vital to understanding England and Wales’ threat picture. Rapport is essential to the establishment and maintenance of effective professional relationships between source handlers and their CHIS. Thus, rapport-based interviewing is a fundamental factor to maximising intelligence yield. The present research gained unprecedented access to 105 real-life audio recorded telephone interactions between England and Wales police source handlers and CHIS. This research quantified both the rapport component behaviours (e.g., attention, positivity, and coordination) displayed by the source handler and the intelligence yielded from the CHIS, in order to investigate the frequencies of these rapport components and their relationship to intelligence yield. Overall rapport, attention and coordination significantly correlated with intelligence yield, while positivity did not. Attention was the most frequently used component of rapport, followed by positivity, and then coordination.

秘密人类情报源 (CHIS) 提供了对犯罪分子和有组织犯罪集团的独特访问，他们收集的情报对于了解英格兰和威尔士的威胁情况至关重要。融洽的关系对于在源处理者和他们的 CHIS 之间建立和维持有效的专业关系至关重要。因此，基于融洽的访谈是最大化情报产出的基本因素。本研究史无前例地访问了英格兰和威尔士警方消息来源处理人员与 CHIS 之间的 105 条真实录音电话交互。这项研究量化了源处理程序显示的融洽关系成分行为（例如，注意力、积极性和协调性）和 CHIS 产生的智能，为了调查这些融洽关系成分的频率及其与智力产出的关系。整体融洽、注意力和协调与智力产出显着相关，而积极性则没有。注意力是融洽关系中最常用的组成部分，其次是积极性，然后是协调性。
