Fatigue resulting from unpredictable or extended working conditions is a factor that negatively impacts the performance of police officers. In this study, we considered how investigative interviewing of children is influenced by interviewer working conditions. We examined two working conditions concerning when interviews were conducted: (a) during early duty shift and (b) an hour before the end of an interviewer’s duty shift and after the end of a shift. We analysed 102 police interviews with children and identified clues that interviews which commenced during early duty shift had more appropriate approaches than interviews in the other condition. Inappropriate approaches were not significantly affected by interviewer working conditions. These outcomes suggest considering new knowledge specific to the behaviour of interviewers according to working conditions and provide promising foundations for further research.

不可预测或长时间的工作条件导致的疲劳是对警务人员绩效产生负面影响的一个因素。在这项研究中，我们考虑了采访者的工作条件如何影响对儿童的调查性采访。我们检查了两种关于何时进行访谈的工作条件：(a) 在早班轮班期间和 (b) 访调员轮班结束前一小时和轮班结束后。我们分析了 102 名警察与儿童的面谈，发现线索表明在早班轮班期间开始的面谈比其他情况下的面谈更合适。不适当的方法不会受到采访者工作条件的显着影响。
