Antecedent Interventions

Antecedent events Immediately precede the occurrence of problem behavior Can be social, environmental, or physiological events Immediately precede desirable behaviors Involve eliminating or modifying antecedent events to decrease problem behavior Types of social and environmental antecedent events Time of day Physical setting Presence of individuals Specific activities Types of physiological antecedent events Middle ear infection Illness and pain Arousal levels Concepts describing the link between antecedents and problem behavior An antecedent event that serves as a cue for a behavior is a discriminative stimulus A behavior that is more likely to occur in the presence of a discriminative stimulus, but not in its absence, is under stimulus control Antecedent intervention strategies Eliminate or modify antecedent events within the environment Decrease problem behavior and promote positive behavior Two common types of antecedent interventions Making Curricular Modifications Altering how a task is presented Modifying the curricular content Identifying student preferences and incorporating student interests Altering the task to ensure the activity has a functional outcome Changing the difficulty level of the task Preventing student errors by modifying the characteristics of the task Altering the way in which an academic task is accomplished Modifying how the instructional content is delivered Providing opportunities for choice making Providing a variety of brief activities instead of one long task Including activities that the student has already been working on successfully Interspersing requests that the student is likely to follow with more difficult tasks Shortening the length of tasks and providing more frequent breaks Including clear visual cues indicating how much work is expected Changing the pace of an activity and making smooth transitions Incorporating strategies that enhance a student's ability to predict upcoming events Antecedent interventions can be used at the classroom level as well
