Most studies of confession during police interrogation have looked at the influence of various individual factors on the prevalence and probability of confession, neglecting potential interactions between factors and the possibility of combined influence on the suspect’s decision to confess or not. To bridge this gap, the present study proposes using a profile-based approach, rather than the much more common variable-based approach, to analyze potential interaction effects, the hierarchical relationship between factors, and the relative weight of each profile/combinaisons of factors in the suspect’s decision-making process. The study is based on self-reported data from a sample of 211 inmates incarcerated in a Canadian federal penitentiary. Results highlight different profiles of factors that play a role in the decision-making process and in the prevalence of confession, particularly the importance of situational factors and the key role of the interrogators. Decisional profiles and the strength of significant factors are discussed in light of the current knowledge on confession and the practical implication of the results for police interrogations is examined. The relevance of decision tree analyses for the field of investigative interviewing is discussed.

警方审讯中的自白:决策树分析

大多数关于警方讯问期间供述的研究都着眼于各种个体因素对供述发生率和概率的影响,而忽略了因素之间潜在的相互作用以及综合影响嫌疑人是否供认决定的可能性。为了弥合这一差距,本研究建议使用基于概况的方法,而不是更常见的基于变量的方法,来分析潜在的相互作用效应、因素之间的层次关系,以及每个概况/因素组合的相对权重在嫌疑人的决策过程中。该研究基于来自加拿大联邦监狱的 211 名囚犯样本的自我报告数据。结果突出了在决策过程和口供流行中发挥作用的因素的不同概况,特别是情境因素的重要性和审讯者的关键作用。根据目前关于供词的知识,讨论了决策概况和重要因素的强度,并研究了结果对警察审讯的实际影响。讨论了决策树分析与调查访谈领域的相关性。
