Fire setting behaviour has devastating consequences and a significant number of adults who set fires have intellectual disabilities and/or autism. However, there has been no comprehensive review of the characteristics and treatment needs of this group of offenders, with existing reviews being limited in terms of sample population and methodological rigour. The purpose of this review was to systematically examine and synthesise existing research to determine what is known about adults with intellectual disabilities and autism who set fires. PsychINFO, PsychARTICLES, Medline, CINAHL Plus with Full Text, Criminal Justice Abstracts, SCOPUS, Open Grey, and the University of Kent arson library were searched for articles. The methodological quality of studies was assessed using the Mixed Methods Appraisal Tool. Searches resulted in 100 articles that met the specific inclusion criteria. Findings indicated adults with intellectual disabilities and autism share some characteristics with other adults who set fires (e.g. aggression, impulsivity). They also face additional challenges, which may have implications for treatment and risk formulation (e.g. communication difficulties, lack of support). However, current research is generally of poor methodological quality, limiting our ability to understand the unique characteristics and treatment needs of this population.

着火行为具有毁灭性后果，大量着火的成年人患有智力障碍和/或自闭症。但是，尚未对这组罪犯的特征和治疗需求进行全面审查，现有的审查在样本人口和方法严谨性方面受到限制。这篇综述的目的是系统地审查和综合现有研究，以了解已知的有智障和自闭症的成年人引起火灾的情况。搜索PsychINFO，PsychARTICLES，Medline，带有全文的CINAHL Plus，刑事司法摘要，SCOPUS，Open Grey和肯特大学纵火图书馆。使用混合方法评估工具评估研究的方法学质量。搜索结果符合特定纳入标准的100篇文章。研究结果表明，智障和自闭症成年人与其他放火的成年人具有某些特征（例如攻击性，冲动性）。他们还面临其他挑战，可能对治疗和风险制定产生影响（例如，沟通困难，缺乏支持）。但是，当前的研究通常方法学质量较差，限制了我们了解该人群独特特征和治疗需求的能力。沟通困难，缺乏支持）。但是，当前的研究通常方法学质量较差，限制了我们了解该人群独特特征和治疗需求的能力。沟通困难，缺乏支持）。但是，当前的研究通常方法学质量较差，限制了我们了解该人群独特特征和治疗需求的能力。
