A behavior checklist describes specific skills and conditions that should be observed. Behavior checklists are customized based on individual needs. They can be arranged by hierarchy (of most important behavior or skill to treat), target one specific behavior or skill area, or address multiple behaviors or skill areas. Behavior Checklists commonly use a Likert scale to rate responses. Behavior checklists are often initially introduced to monitor behaviors by caregivers and therapists. After, they are used as a self management system as an individual becomes ready to independently self monitor their own behaviors. As an example, prior to beginning a therapy session a therapist may present a checklist of items that needs to be completed and/or a list of behaviors that need to be maintained during the session. An item would be checked off the list as expectations are met. Reinforcement is often contingent upon the completion of behavior checklists.
