Antecedent Strategies: Prevention Practices


Antecedents refer to environmental conditions or stimulus changes that exist or occur prior to the behaviour of interest. These strategies are implemented to reduce the frequency of interfering behaviours. This course will discuss antecedent strategies applicable to each function of behaviour. Function based antecedent strategies require identification of the variables maintaining interfering problem behaviour. Once identified then one component of the operant contingency is manipulated.

Course Description

Antecedent strategies are preventative approaches implemented to reduce the frequency of interfering behaviours. An antecedent intervention is implemented at the start of a session and dictates how a session is set up. These can be contingency dependent and contingency independent behaviour interventions. A contingency dependent strategy is dependent on the consequence of behaviour for developing evocative and abative effects, these would be considered function-interventions. Whereas, a contingency independent strategy is not dependent on the consequences of behaviour for developing evocative and abative effects. Therefore, the antecedent itself affects behaviour-consequence relations.

This course will walk you through antecedent strategies relevant to each function of behaviour, i.e. escape, attention, access to tangibles and sensory. It will also highlight the temporary effects of antecedent interventions.


Participants Will:

  • Learn about what antecedent strategies are
  • Learn about antecedent strategies based on function
  • Learn about how to implement antecedent strategies
