Many instances of maladaptive behaviors are due at least in part to a lack of social skills. Although there are effective interventions for teaching social skills, generalization of trained social skills remains a challenge. One promising way to enhance generalization may be to use functional behavior assessments to select social skills to teach that can meet individuals’ specific needs. This chapter describes a process for embedding function-based support into social skills interventions that may generalize to untrained settings. The chapter concludes with a case study demonstrating generalization of positive peer interaction from recess to a classroom setting for a grade two student. Results indicated that the student’s behavior during recess and during classroom instruction both changed upon implementation of the recess intervention, and these behaviors maintained over three months after the intervention was withdrawn.
