Delivers the first uniform diagnostic classification system for conducting FBAs

This manual presents a unique pioneering classification system, written by the author of a bestselling textbook on functional behavioral assessment, for school psychologists and other personnel who conduct FBAs for problem behaviors. It renovates the idiosyncratic terminology currently used by school psychologists with a standard classification system for selecting a hypothesis about the function of problem behavior for FBAs.

The manual presents a uniform set of functions derived from environment-behavior relations. This includes 13 possible functions within four major categories. For each function, there is a general description, explanation, and illustrative examples of the category. Also included are practice case illustrations to facilitate understanding of how to diagnose the function and its category.
