Children and adolescents in the general population and in clinical populations reveal surprisingly high rates of playing with fire or actual firesetting behavior. A single fire has the potential to cause a cascade of serious consequences to the child, family, and the community, some of which may continue forever. Yet, there is limited practical information and advice based on available empirical evidence to help programs or practitioners work effectively with children or adolescents who misuse fire, and their families. This book provides practical guidelines designed to facilitate the clinical assessment and treatment of youthful firesetting behavior based on nearly four decades of research and intervention experience with this population. The topics covered in this book address several important content areas. Initial chapters provide an overview of the significance of the problem, and some lessons learned based on case control, clinical trial, and real-world implementation projects. Recommendations for using screening and assessment measures that evaluate firesetting and general psychosocial issues are included. Several intervention methods are outlined for use with children, caregivers, and families. These methods encompass fire safety education materials and several cognitive-behavioral treatment skills-training procedures that focus on understanding of the fire, affect regulation and self-control, parenting practices, and home-based management programs. The book also includes suggestions to promote professional and program development which reflect on various educational, ethical, legal, collaborative, and community safety considerations. The book’s content is intended to help a diverse array of practitioners understand and target the context in which the misuse of fire occurs.
