"Applied Behaviour Analysis (ABA)" is an effective behavioural treatment programme widely used with children with autism to improve socially significant behaviours. This practical book gives guidance on how to develop a tailored ABA programme that includes the key features of ABA: detailed individual behaviour assessment, reinforcement strategies to encourage new behaviours and systematic programme implementation. Chapters also include individual family case studies and discuss relevant issues such as day-to-day management of programmes for both younger and older children, collaboration in the community, sibling support, school-based programmes and obtaining services. The international contributors offer practical advice on the approach needed for the successful implementation of ABA.
