A functional analysis of recidivistic arson.

Evidence from studies of pathological arson and normal fire setting as well as the authors' clinical experience with arsonists in a maximum security hospital is employed to generate a model of recidivistic arson within the conceptual framework of functional analysis. It is contended that certain psychosocial stimuli, in the context of major setting conditions, predispose the individual towards incendiarism which is initially positively and negatively reinforced. However, the longer-term consequences of arson are considered to maintain and exacerbate the antecedent problems encountered by arsonists. Specifically, arson is viewed as an attempt to exert a change in the arsonist's life conditions where alternative behaviours have proved, or are perceived to be, ineffective. The model incorporates adaptations of the displaced aggression and arousal hypotheses of arson, and examines possible developmental aspects of pathological arson from normal childhood fire play, and suggests that a transition from fire setting in the company of others to incendiarism alone constitutes a major factor in the pathological process. The social, clinical and theoretical implications of the model are discussed with reference to current management and treatment strategies as well as future research.
