Abstract:Credibility of a person or source, consisting of his or her expertise and reliability, is important in many processes of communication. This research examines the effect of credibility of a police officer on interview outcomes such as information provision, the extent to which suspects admit to a crime and the perceived quality of the relation with the police officer. A moderating effect of cultural background from the suspect is expected; we expect expertise leads to better interview outcomes, especially for low context suspects. In addition, we expect reliability leads to better interview outcomes too, but especially for high context suspects. Finally, we predict a mediating role of perception of the suspect from the credibility of the police officer in the relation between credible behaviour of the police officer and interview outcomes. Hypothesis were examined with secondary data analysis; used data is coming from the study from Beune, Giebels, & Sanders (2009). Herewith were 52 male students, used as suspects, interviewed by 52 experienced police officers in a field experiment. The suspects were accused of theft, which was a rightful accusation; every suspects had stolen money in a controlled setting. The interviews were taped on video and sentences from the police officer and the suspect were encoded afterwards on basis of influencing behaviour and interview outcomes. Perception of the credibility of the police officer and the perceived quality of the relation was measured by items in a questionnaire, which suspects filled in after the interview. Results showed that expertise had a negative effect on uncovering the truth, for both low context suspects as high context suspects. Reliability had none effect on interview outcomes. The cultural background of the suspect caused some differences in interview outcomes. Some explanations of these results are given in the discussion.
