Abstract:Despite the large focus on techniques, such as building rapport and approaches like accusatory or humanitarian styles, that are most effective in investigative interviews, it remains unclear what role the personality of the interviewee plays and in how far techniques need to be tailored. Therefore, this study aims to investigate how the personality of the interviewee mediates the relationship between interview style and rapport. The study was completely carried out online. First, a survey investigated the personality of the participants (n = 50) based on the Big Five Model of Personality. Following, investigative interviews about a crime vignette, in which an iPhone was stolen, in either the accusatory or humanitarian condition, were conducted through a video call. Lastly, a follow up survey examined how much rapport the participants build with the interviewer. A significantly larger amount of rapport appeared in the humanitarian condition compared to the accusatory condition. This study was not able to detect significant moderation effects for most of the personality traits. Nonetheless, an exploratory analysis found a moderation effect of low agreeableness. While the humanitarian approach was maximally effective at low levels agreeableness, the accusatory approach was maximally ineffective.
