An Evaluation of Operant Behavioural Economics in Functional Communication Training for Severe Problem Behaviour.

: This single-case experiment examined the use of behavioural economic concepts in a function-based treatment for problem behaviour. : Behavioural economic analyses were used to evaluate the strength of functions of problem behaviour and this information was used to inform elements of function-based treatment for one child with a neurodevelopmental disorder. : Findings from this experiment indicated that the incorporation of behavioural economic measures resulted in positive treatment effects that were maintained throughout all phases of the evaluation, including those implemented by caregivers. : These results suggest that behavioural economic concepts and procedures can be successful adjuncts to evidence-based assessments and treatments for problem behaviour.
