| Sumario: | Objective: This study investigated whether a group of firesetters ( n = 68) could be distinguished, psychologically, from a matched group of non-firesetting offenders ( n = 68). Method: 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. Results: 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. Conclusions: 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.
