A practical guide to assessing adult firesetters’ fire-specific treatment needs using the Four Factor Fire Scales

Objective: Practitioners working with offenders who have set fires have access to very few

measures examining fire-specific treatment needs (e.g., fire interest, fire attitudes). In this paper, we examine the new Four Factor Fire Scales (Ó Ciardha et al., 2014), which may be used by practitioners to examine fire-specific treatment needs for offenders who have set deliberate fires. We present a standardized scoring procedure when using these scales, as well as an associated scoring template for practitioner use.

Method: Norm data are based on male and female firesetters (n=378) and non-firesetters (n=187) recruited from 19 prison establishments (including 6 female establishments, 1 Young Offender Institutions) and 12 secure mixed gender mental health settings.

Results: We present a full overview of all data we have collected to date relating to the Four Factor Fire Scales across prison, mental health and young offending participants. For each population, we present mean scores as well as associated cut off scores and reliable change indices to aid practitioners in their interpretation of scores.

Conclusions: The Four Factor Fire Scale provides professionals working in the area with a robust template for administering, scoring, and interpreting the fire-specific factors currently identified as playing a role in deliberate firesetting behavior. Strengths and limitations of the measure are discussed.
