The current study focuses on the beliefs and practices of Belgian police officers (N = 177) concerning suspect interviews. Enhancing and safeguarding the quality of suspect interviews can prevent miscarriages of justice, and a comprehensive understanding of the process is crucial. While prior research has explored suspects’ perspectives on this issue, there has been no comprehensive study on European police officers’ beliefs and practices. This study aims to fill this gap by investigating the attitudes of Belgian officers in two studies. Study 1 included Flemish-speaking police officers (N = 130), and Study 2 included French and German-speaking officers (N = 47). Using a self-report survey, officers were questioned about the duration, frequency, and recording of suspect interviews, suspects’ use of legal rights, deception detection ability, (false) confession rates, and the use of various interviewing techniques. The findings suggest a positive shift in the Belgian approach to suspect interviewing, with more adherence to guidelines for minimizing false confessions. However, some officers still reported using accusatorial tactics, indicating that interviewing training in Belgium could benefit from more uniformity. By understanding the beliefs and practices of police officers, we can work towards developing effective interviewing techniques that protect the rights of suspects and promote justice.

本研究的重点是比利时警察（N  = 177）在约谈嫌疑人时的信念和做法。提高和保障嫌疑人讯问的质量可以防止误判，全面了解这一过程至关重要。虽然之前的研究探讨了嫌疑人对此问题的看法，但尚未对欧洲警察的信念和做法进行全面的研究。本研究旨在通过调查两项研究中比利时军官的态度来填补这一空白。研究 1 包括讲佛兰芒语的警官 ( N  = 130)，研究 2 包括讲法语和德语的警官 ( N  = 47)。通过自我报告调查，警员被问及嫌疑人讯问的持续时间、频率和记录、嫌疑人使用合法权利的情况、欺骗侦查能力、（虚假）供述率以及各种讯问技术的使用。研究结果表明，比利时审问嫌疑人的方法发生了积极转变，更加遵守了尽量减少虚假供述的准则。然而，一些官员仍然报告使用指责策略，这表明比利时的面谈培训可能会受益于更加统一。通过了解警官的信念和做法，我们可以努力开发有效的访谈技巧，以保护嫌疑人的权利并促进正义。
