This study investigated whether a group of firesetters (n = 68) could be distinguished, psychologically, from a matched group of non-firesetting offenders (n = 68).
Participants completed measures examining psychological variables relating to fire, emotional/self-regulation, social competency, self-concept, boredom proneness, and impression management. Official prison records were also examined to record offending history and other offense-related variables. A series of MANOVAs were conducted with conceptually related measures identified as the dependent variables. Follow-up discriminant function and clinical cut-off score analyses were also conducted to examine the best discriminating variables for firesetters.
Firesetters were clearly distinguishable, statistically, from non-firesetters on three groups of conceptually related measures relating to: fire, emotional/self-regulation, and self-concept. The most successful variables for the discrimination of firesetters determined via statistical and clinical significance testing were higher levels of anger-related cognition, interest in serious fires, and identification with fire and lower levels of perceived fire safety awareness, general self-esteem, and external locus of control.
Firesetters appear to be a specialist group of offenders who hold unique psychological characteristics. Firesetters are likely to require specialist treatment to target these psychological needs as opposed to generic offending behavior programs.
本研究旨在探究一组纵火犯(n=68)是否在心理上可以与匹配的非纵火犯罪者(n=68)区分开来。
参与者完成了与火、情绪/自我调节、社交能力、自我概念、易无聊和印象管理相关的心理变量的测量。同时还查阅了官方监狱记录,以记录犯罪历史和其他与犯罪相关的变量。进行了一系列 MANOVAs 分析,将概念上相关的测量作为因变量。还进行了后续的判别函数和临床临界分数分析,以检验纵火犯的最佳判别变量。
纵火犯在与火、情绪/自我调节和自我概念相关的三组概念上相关的测量上,与非纵火犯在统计学上有明显区别。通过统计和临床意义测试确定的纵火犯最佳判别变量为:与愤怒相关的认知水平较高、对严重火灾的兴趣、对火的认同以及对火灾安全意识、一般自尊心和外部控制感的感知较低。
纵火犯似乎是一个具有独特心理特征的特定犯罪者群体。纵火犯可能需要专门的治疗来满足这些心理需求,而不是通用的犯罪行为方案。
