The model of intensive ABA service can be compared to the medical intensive care unit. While in the latter service delivery we may expect multi-organ failure, in the former service we expect an individual with multiple psychological system failure (attention, imitation, compliance, pointing, etc.).
The function of intensive ABA service is to stabilize the individual in terms of his/her ability to engage in social referencing, shared attention, basic and complex imitation and compliance skills. At the core of the intensive ABA model of care is to teach parents to become the environment which sustains the continued care of the individual through daily routines and activities using the procedures of ABA.
