The overall purpose of this book is to provide a highly practical guide for school professionals to efficiently address cases of youth with school refusal behavior at different levels of severity and complexity. School refusal behavior can consist of full or part-day absences, tardiness, skipped classes, morning misbehaviors in an attempt to miss school, and school attendance under considerable duress. School refusal behavior is a pervasive and difficult problem faced by many types of mental health professionals (e.g., psychologists, psychiatrists, marriage and family therapists), school officials (e.g., administrators, guidance counselors, school-based social workers, school psychologists), and others (e.g., pediatricians, probation officers). School refusal behavior, even in mild forms, has been shown to be a significant risk factor for social, behavioral, and academic problems in middle childhood and adolescence as well as psychiatric, economic, and occupational difficulties in adulthood. This book provides assessment and intervention strategies along a multi-tiered model that includes systemic approaches to prevent school absenteeism (Tier 1), clinical techniques for emerging or moderate cases of absenteeism (Tier 2), and educational and other procedures for chronic and severe cases of absenteeism (Tier 3).
