ABA is an acronym for applied behaviour analysis. Applied behaviour analysis is a systematic way of observing someone's behaviour, identifying desirable changes in that behaviour and then using the most appropriate methods to make those changes.
The principles of applied behaviour analysis are incorporated within many specific interventions (such as discrete trial training, incidental teaching and pivotal response training).
Please see Applied Behaviour Analysis for more information.
ABA is also sometimes used to refer to some comprehensive, multi-component programmes (especially early intensive behavioural programmes such as the University of California at Los Angeles Young Autism Project model).
Please see UCLA YAP model for more information.
