Sexual Offending Literature as a Guiding Framework
Given the paucity of the adult firesetting literature pre-2010, researchers turned to more established literatures (i.e., sexual offending) to inform the research agenda moving forward. However, although early theorising suggested a relationship between firesetting and sexual dysfunction, little available evidence substantiates this link as a major explanatory factor for adult firesetting (Ó Ciardha, 2015). Research on sexual offending has nonetheless been influential in developing knowledge relating to firesetting. This is likely the result of the longstanding recognition of sexual offending—particularly child sexual abuse—as a public health problem in need of sustained research to develop knowledge for prevention and treatment. As a result, the burgeoning field of research on deliberate adult firesetting has been able to draw on practices and concepts from the more established field of research on sexual offending.
A key influence of the field of sexual offending on firesetting research has been work by Tony Ward and various collaborators. The Multi-Trajectory Theory of Adult Firesetting (M-TTAF; Gannon et al., 2012) is an example of theorising in firesetting that draws inspiration from work, including that of Ward and Beech (2006), Ward and Hudson (1998), and Ward et al. (2006), on how to effectively develop, appraise, and knit together theories in sexual offending. Models of the offence process (micro theories) of firesetting behaviour (e.g., Barnoux et al., 2015; Tyler et al., 2014) also used methods applied by Ward et al. (1995) to the investigation of the offence process of people who sexually offend against children. Furthermore, Ward hypothesised that implicit theories (Ward, 2000; Ward & Keenan, 1999) and offence scripts (Ward & Hudson, 2000) form part of an explanatory framework for the offence-supportive belief systems of people who commit sexual offences. These concepts have been highly influential in theory development (e.g., Butler & Gannon, 2015; Ó Ciardha & Gannon, 2012; see Chapter 3) and empirical research (e.g., Barrowcliffe et al., 2019; Butler & Gannon, 2021) on firesetting behaviour.
Changes and developments in the treatment of sexual offending over the past number of decades have also influenced current practice in the treatment of firesetting. For example, those interested in best practice with people who have sexually offended have been confronted with questions around dealing with clients who deny or minimise their offending. Similarly practice regarding treatment of sexual offending has had to navigate whether treatment ethos is most effective using a risk-based or a strengths-based approach. Building from the evidence base around what works for sexual offending has allowed contemporary intervention programmes for people who have been apprehended for firesetting (see Chapters 6 and 7) to be developed, conscious of principles of risk, need, and responsivity (Andrews & Bonta, 2010) and strength-based approaches to treatment (Good Lives Model; Ward & Stewart, 2003). These intervention programmes have been able to avoid the pitfalls faced by early sexual offending practice whereby denial and minimisation posed barriers to treatment involvement (Maruna & Mann, 2006).
Book Rationale
This chapter has provided some of the context surrounding the emergence, in the past decade and a half, of research on deliberate adult firesetting as a coherent field of enquiry. Given the relative nascence of this field, some may ask whether an entire book devoted to the assessment and treatment of adults who set fires is necessary.
At times, firesetting has been viewed as one behaviour amongst a broad repertoire of offending, whereby the individual is generally antisocial (i.e., the generalist hypothesis; Gannon et al., 2013). There is some research evidence to suggest that people who set fires are likely to also commit other types of offences (e.g., Soothill et al., 2004), and they are more likely to recidivate in ways other than firesetting (see Chapter 4). Based on these findings, it could be argued that firesetting does not warrant special attention. However, there is a growing body of evidence that support the specialist hypothesis—that some people who set fires do not commit other forms of offending—or that people with firesetting convictions may represent a distinct population within correctional settings (Gannon et al., 2013). In other words, it appears that many individuals with a history of adult firesetting have distinct psychological and psychopathological features (see Chapter 2) that require a more tailored approach to treatment. Such targeting of these likely criminogenic needs is fundamental to the effectiveness of forensic clinical practice (see Bonta & Andrews, 2017).
The fact that emerging literature suggests that people who set fires represent a population within the criminal justice and healthcare systems that experience specific needs demonstrates how our understanding of deliberate adult firesetting has changed in a short period of time. We argue that this book is timely because it allows us to synthesise the findings of a rapidly expanding field while highlighting where the gaps remain in our knowledge and where new ways of working are needed in terms of the data that public agencies and researchers gather; the manner in which researchers approach hypothesis testing around the aetiology, assessment, and treatment of people who set fires; and the ways in which practitioners work with this population.
Concluding Remarks
This book consolidates the research evidence into a practical guide to inform the assessment and treatment of adults who set fires. Evidence-based practice is the ultimate goal. However, admittedly, many elements of this book are evidence-informed (Bonta & Andrews, 2017) rather than evidence-based. As discussed in this chapter and further interrogated throughout this book, the research literature is yet to be saturated with clinical trials and/or quasi-experimental research designs evaluating varying methods to assess risk and reduce reoffending. Nonetheless, existing theories and research do provide sufficient steer for clinicians to make informed judgements.
Note
1 1 If firesetting rates were not reported per 100,000 in the sources we cite, we calculated this rate based on the reported firesetting statistic relative to the approximate population size in the relevant year. Doing so allowed us to report prevalence of firesetting in a standardised way across studies or sources.
2 Key Characteristics and Clinical Features of Individuals Who Set Deliberate Fires
Describing the characteristics of who sets fires will not be particularly informative unless we begin by noting two important considerations. First, there is no one personality or psychopathology that defines individuals who set fires. These individuals are heterogeneous in their characteristics, offending histories, and motives for setting fires. Second, consideration of the factors that differentiate people who engage in criminal firesetting (i.e., apprehended or non-apprehended) from people in the general population who have not engaged in criminal behaviour differs from consideration of the factors that differentiate people who have engaged in criminal firesetting from other justice-involved individuals who have not set fires. This distinction is important. If people who set fires are indistinguishable—psychologically speaking—from the general population, then practitioners have no treatment targets to address in prevention or treatment initiatives. If individuals apprehended for firesetting are indistinguishable from other justice-involved
