Trauma narratives: recommendations for investigative interviewing.

In the investigation of a criminal event, the police may encounter witnesses or victims experiencing symptoms of being traumatized (e.g. anxiety, intrusive thoughts or avoidance of trauma-related stimuli). This may pose a challenge in investigative interviews where police interviewers aim to obtain reliable and detailed accounts. Based on previous theory and research, this theoretical paper aims to outline recommendations for police interviewers for approaching traumatized adult witnesses to facilitate communication, attend to the well-being of the individual and reach investigative aims. First, factors considered important for preparing for the interview and building rapport are presented. Then, different aspects of how to facilitate the interviewee's account will be described with an emphasis on how police interviewers can approach emotional reactions to maintain rapport.
