IISCA is an acronym for an interview-informed synthesized contingency analysis. A successful IISCA serves as an effective baseline context to treat problem behavior and develop important social repertoires. SBT is the acronym for Skill-Based Treatment, a type of intervention based on the principles of ABA used to reduce problem behaviors. Today, it appears to be one of the most effective interventions in the literature for the treatment of problem behaviors and the teaching of new skills in individuals with autism or disabilities.
