Function of Behavior

Understanding the function of a behavior is a cornerstone of Applied Behavior Analysis.

Why does Julia grab a toy from her brother? Is it to gain access to the toy? Or maybe it's to access Mom's attention?

When you can identify the function of the behavior, you can limit reinforcement for the undesired behavior and work to teach a functionally equivalent replacement behavior.

This questionnaire is designed to help you consider when a behavior is most likely to occur. There are 9 groups of 6 possibilities. In each of the 9 groups, select the option that best describes the target behavior. The results will show you a likely function of the behavior. You can retake the questionnaire to see you you get the same results.

While questionnaires are a useful tool, they should supplement (not replace) other ABA strategies including collection ABC data.
