Functional Behavior Assessments and Postive Behavior Support Plans

Behavior is Functional

The primary principle of function-based behavior support is that individuals act the way they do for a reason. That is, most behavior is functional: it serves a purpose. The function of the behavior may be to obtain something the person wants, to generate adult or peer attention, or to escape from an aversive situation or person. The results or consequences of behavior affect the future occurrence of behavior.

A behavioral intervention has two primary goals: reduce problem behavior and increase appropriate behavior. There are at least three means to meet these goals:

1. Make the problem behavior irrelevant. Decrease or eliminate the need to engage in the behavior.

2. Make the problem behavior inefficient. Provide the child with a replacement behavior that serves the same function as the inappropriate behavior.

3. Make the problem behavior ineffective. Do not allow the child to obtain what he or she wants through inappropriate behavior.

FBA and PBSP Guidance

The VBISD Behavior Committee has developed comprehensive resources to guide teams in the completion of quality Functional Behavior Assessments and Positive Behavior Support Plans. Using the DASH framework, teams in Van Buren County are trained to:

Define the behavior of concern (in observable and measurable terms)

Ask about the behavior (via interviewing tools like the Functional Assessment Checklist for Teachers/Staff)

See the behavior by completing ABC Data Observation

Hypothesize the function of the behavior based on evidence collected through the interview, observation, and other data collection methods

After developing a supported hypothesis statement, teams are then trained in identifying appropriate replacement behaviors, matching interventions to the function of the behavior, and constructing plans for implementation.
