Behavioural Concerns and Autistic Spectrum Disorders: Explanations and Strategies for Change is a practical and comprehensive account of how people who attract autism labels can come to behave in ways that give rise to serious concerns in other people and, sometimes, themselves. The authors identify the range of needs that may be expressed through behaviours that cause concern and provide strategies for addressing both needs and behaviours. These strategies are based on extensive research and on the authors' own clinical experience. Each aspect of need is analysed in detail. General principles for dealing with these needs are presented, and in each case a 'tips and hints' section offers more specific help on possible solutions. Included in the appendices are advice on identifying the factors behind a behaviour that causes concern and guidance on how to ensure that support services are delivering what they should. This is a book that will be essential reading for all those working or living with autistic people.
