Police interrogation instruction – A scoping review on teaching interrogation and its relevance to investigative interviewing processes

Best practice investigative interview methods are crucial to the criminal investigative process, especially if there is little or no material evidence available The course of police inve­stigations is frequently determined by the quality of witness accounts and suspect interviews Despite the availability of expert literature, police officers use only a small amount of knowledge in practice This leads to the questions, to what is the scientific knowledge on the contents and the metho­dology in investigative police interview training And to what extent is it transferred into police education and training programs, and in what way is the knowledge taught in such programs. To answer these questions, this paper presents a scoping review of the literature The search was performed in Scopus, PubPsych, KrimLit, Beck-online and Juris, PsycINFO, PsycARTICLES, PSYNDEX Studies were analysed in a tabu­lar and narrative way 6,108 studies were identified, 23 met eligibility criteria Findings present the following research on police interview training: acceptance of scientific results, rapport, the Cognitive Interview and cognate methods, lie detection, and interviewing children, predominantly as vic­tims of sexual assault The paper identifies several factors for enhancing the various aspects of police interview training It provides a framework of practical implications, that can be conducted considering police officers' experience and the degree of their operational specialization.
