ABC-Iceberg (ABC-I)

The ABC-Iceberg (ABC-I; Aspy & Grossman, 2011) is a form used to examine the antecedents, behaviors, and consequences observed and to consider the characteristics of autism as they relate to the observed behavior.


The tool is used in conjunction with the Underlying Characteristics Checklist (UCC; Aspy & Grossman, 2011b). The purpose of the ABC-I is to develop comprehensive interventions that target behaviors in addition to core features of autism spectrum disorder.
