摘要

摘要尽管纵火者中普遍存在精神障碍,但关于纵火如何在不同精神状况的人中表现出来的实证研究有限。在这项研究中,使用分类方法来探索精神障碍患者犯下的不同类型的纵火行为。动机、诊断、情境和行为变量之间的关联也被观察到,以阐明精神障碍和纵火之间的关系。使用了103名精神障碍消防员的样本,他们被转介到社区法医心理健康服务机构。使用多维量表对精神障碍患者的四种纵火行为进行了区分:(1)精神斗争,(2)绝望,(3)调节障碍和(4)火灾兴趣。在前两种类型的纵火中,复仇和自杀的动机主要来源于精神病症状,并且观察到精神病与纵火之间有更直接的关系。相反,后两种类型的动机分别与人格障碍和纵火狂有关,表现为沮丧和寻求刺激。这些类型表明了纵火的途径,其中相应的精神障碍似乎加剧了纵火的易感性。讨论了对临床配方和理论发展的影响,强调需要更好地理解纵火的病因,包括潜在的动机、精神病理学和背景。

Firesetting among People with Mental Disorders: Differences in Diagnosis, Motives and Behaviour
Abstract Despite the prevalence of mental disorder among firesetters, there is limited empirical research on how firesetting manifests in people with different psychiatric conditions. In this study, classification methodology was used to explore different types of firesetting committed by people with mental disorders. Associations between motives, diagnoses, situational, and behavioral variables were also observed to clarify the nexus between mental disorder and firesetting. A sample of 103 mentally disordered firesetters referred to community-based forensic mental health services was used. Four types of firesetting perpetrated by people with mental disorders were differentiated using multidimensional scaling: (1) Psychotic Struggle, (2) Hopeless, (3) Dysregulated, and (4) Fire Interest. In the first two types of firesetting, motives of revenge and suicide were mainly derived from psychotic symptoms and a more direct relationship between psychosis and firesetting was observed. Conversely, the latter two types featured motives of express frustration and excitement seeking, in association with personality disorder and pyromania, respectively. These types indicated pathways to firesetting wherein the corresponding mental disorder appeared to exacerbate predisposing vulnerabilities for firesetting. The implications for clinical formulation and theory development are discussed, emphasizing the need to better understand the etiology of firesetting including the underlying motives, psychopathology and context.
