Antecedent and consequence control

Therapy and consultation cannot be effective unless the behaviours to be changed are understood within a particular context. The process of understanding behaviour in context is known as functional behavioural assessment. Thus, a functional behavioural assessment is required before performing behaviour modification. One of the simplest yet effective methods of functional behavioural assessment is known as the "ABC" approach, where observations are made on Antecedents, Behaviours, and Consequences.
