Police interviews with suspected child sex offenders: does question type, empathy, or interviewer training influence the amount of investigation relevant information obtained?

Using transcripts of 26 real-life interviews with suspected child sex offenders from England, this study examined the use of empathy and the impact of question type on the amount of investigation relevant information (IRI) obtained. There were no significant differences in the amount of IRI obtained in the interviews as a function of the use of empathy by police officers. The mean proportion of inappropriate questions was significantly higher than the mean proportion of appropriate questions and, as hypothesized, the responses to appropriate questions contained significantly more items of IRI than responses to inappropriate questions.
