A Guide to Services for Children with Autistic Spectrum Disorders for Commissioners and Providers 1 ntroduction
Introduction
This guide is for commissioners and providers in education, health, social services and the voluntary/independent sectors. Its purpose is to serve as a brief guide to autistic spectrum disorders, and developments in education and social welfare with respect to those disorders. It aims to help authorities fulfil their obligations under the United Nations Convention on the Rights of the Child (1989) and to provide a range of services to meet the needs of the individual child with an autistic spectrum disorder.

What is an Autistic Spectrum Disorder?
Autistic spectrum disorder is the name given to a range of developmental disorders that share certain characteristics. It includes the core condition of ‘autism’, and categories such as Asperger’s syndrome (AS), used for those without language delay and with average or above levels of intelligence. Children who share the following triad of developmental impairments also share needs leading to similar practical and service implications (Special Educational Provision, DfE, 1996; Children in Need Provision, Children Act, 1989).
The Triad of Impairments in Autistic Spectrum Disorders
Social understanding and interaction: This is the most characteristic developmental disturbance in autistic spectrum disorders. The difficulty in acquiring social skills stems from a difficulty in processing social and emotional information, which is not readily solved through teaching social skills alone. The normal intuitive ‘fast track’ processing of social information is disturbed, so the child has to use slower more general cognitive processes. This has two important consequences: it is difficult to process social information while performing other cognitive tasks (making learning in normal social educational situations problematic) and processing social information without a natural intuitive route is so complex that only the most able are able to do so, and not without considerable stress.
There is, nevertheless, great variation in the social difficulties and sociability of children with autistic spectrum disorders. These differences can be characterised as certain ‘types’: the ‘aloof’child is classically withdrawn, shunning social contact and appearing to live

‘in a world of his/ her own’; the ‘passive’ child is happy to accept social attention from others (as long as it is not too sudden or invasive) but does not initiate it; the ‘active but odd’ child wants social contact, and tries to initiate it, but gets it wrong and cannot work out the social rules and their variations according to context. Wing (1996) added the category of the ‘mildly affected’ individual, where these difficulties are even more subtle and difficult to detect in the young child. These are not rigid categories and the child may move through them in the course of development or through education/ training.
Understanding and using communication: Only in autistic spectrum disorders does language develop separately from communication. Language difficulties or delay frequently accompany autism, yet some children with autistic spectrum disorders may have language as a special area of skill. All, however, will have difficulties in communicating, regardless of any mechanical language skill. The child without a spoken language will not be able to compensate (as others do) by the acquisition of a sign language, although augmentative systems may be an aid to developing language.
The problem is making sense of communication in all its forms - speech, intonation, mood, gesture, body posture, personal interactive space, sign, writing and visual symbols, although the latter are easier to acquire because they are visual and uniform. The child who fails to acquire any spoken language, and struggles with signs, is at least recognised as having a problem, even though its real nature may not be understood. The child with good speech, however, is often misunderstood, with his/ her difficulties being attributed to behaviour problems.

Flexibility of thinking and behaviour: Some formulations of the ‘triad’ include a lack of imagination, but that is not really accurate. The real difference from their intellectual peers is in social imagination. Thus, if they have sufficient intellectual ability, they may engage in pretend play but still have problems doing so with others and in sharing pretence. More able children may engage in complex imaginative games or creative activities, but as a solitary pursuit which tends to be more repetitive. The difficulties with imagination involve distinguishing the real from the imagined or dreamt. Children with autistic spectrum disorders do not generally understand or enjoy children’s fiction but they do like repetitive tales and particular stories where the social element is reduced in favour of mechanical ‘heroes’ and exciting physical events, the classical favourite being Thomas the Tank Engine stories - especially on video.
More characteristic are difficulties in flexible thinking and behaviour, no matter how high the general intelligence. The child finds it difficult to initiate actions without prompting or cueing, to inhibit behaviour, to switch attention, and to monitor or reflect on his/ her own learning, experiences, knowledge or feelings.
Levels of Explanation
Autistic spectrum disorders can be considered at three different levels of explanation: behavioural, biological and psychological. The behavioural level is the level currently needed for diagnosis, although eventually it may be possible to provide a biological ‘test’ for the condition. When it comes to treatment and the provision of services, biological causation may not be significant and behaviour alone may be misleading, depending, as it does, on many other

factors. It is the level of psychological functioning - the way the individual perceives, thinks, learns and feels that offers a better guide as to what is needed.
Individual Differences
Individuals with autistic spectrum disorders are very different from one another, reflecting differences in the severity of the autism, any additional disorder, the level of intelligence, the level of language ability and the personal qualities and experiences of each individual. They will share the triadic difficulties, but the way these are expressed will differ. Each person needs to be understood as an individual. There is nothing that children with autistic spectrum disorders do that the rest of us do not, at least under similar conditions of stress, but it is likely that what they do may be inappropriate in the social situation or differ in severity and extent.
Associated Conditions
There will often be additional developmental difficulties, such as language disorders, although there will seldom be a dual diagnosis. If a child with an autistic spectrum disorder develops no speech, for example, in spite of good non-verbal intellectual development, one would suspect an additional language impairment, but many associated language disorders are more subtle.
Motor problems too may co-occur (not just the ‘clumsiness’ associated with AS) including dyspraxia, which is disturbance in the planning and implementation of voluntary movements, while leaving automatic or cued actions undisturbed. Some children are extremely agile, with an ability to run along ledges without faltering and to climb up anything, no matter how precarious, while others

are extremely disturbed by any activity involving balance and may not even manage to walk on uneven surfaces such as grass or sand.
Children with autistic spectrum disorders may have other developmental disorders such as sensory loss or Down’s syndrome, although there may then be a considerable delay in picking up the ‘autistic’ difficulties. Other conditions may be associated with the spectrum as a possible cause; these include tuberous sclerosis and Fragile-X syndrome. Tourette’s syndrome can cause problems with differential diagnosis but the two conditions often co-exist. Epilepsy, especially late-onset epilepsy, is strongly associated with autism, especially, but not exclusively, when there are additional learning difficulties. Additional learning difficulties (mild, moderate, severe or profound) occur alongside autism itself in around three quarters of cases and, like all the other developmental difficulties, interact with the autism in their effects on development and learning.
Mental health problems: Autistic spectrum disorders can become associated with mental health problems. In late adolescence there may be depression, allied to lack of self-esteem and anxiety about the future. This is particularly so where problems are misidentified and appropriate help is not available. Bi-polar disorders may also occur, with problems sometimes in distinguishing the manic and depressed stages from the symptoms of the autistic spectrum disorder. Some adolescents receive a diagnosis of schizophrenia, due to some superficial similarity of symptoms, or misunderstandings during the diagnostic interview. It is possible to develop schizophrenia when one has an autistic spectrum disorder, but misunderstandings about the interpretation of ‘symptoms’ are more likely.

Identification and Diagnosis
First signs: Parents are usually the first to recognise that something is wrong, although that depends on the severity of the autistic spectrum disorder, whether there are accompanying difficulties, and the experience of the parents. Typically, it is an accompanying problem that may first cause concern such as failure to develop speech, delay in developmental milestones, or hyperactivity. Parents may often sense that there is something else - that their child is simply not responding to them as they should and (crucially) not initiating contact. At one extreme is the passive child who is ‘too good’ as a baby - content to be alone unless hungry, or uncomfortable. At the other, is the hyperactive baby who never seems to sleep, is constantly irritable and fails to be comforted or soothed. Sometimes, there is a combination, with the baby never seeking attention but reacting negatively to human contact even when having basic needs met, such as feeding.
The more able the child, and the fewer the accompanying difficulties, the harder the autistic spectrum disorder becomes to detect. Children with AS, for example, are less likely to be picked up before school since they may react relatively well to parents and known adults but have increasing difficulties in relating to peers, especially in groups. Even at school or nursery, when difficulties become apparent, they are often put down to other factors. Parents find it hard to manage their young children with an autistic spectrum disorder, but problems in the parent-child relationship are more likely to be the result of the child’s difficulties than the cause of them.

Obtaining a diagnosis: Evidence shows that there is considerable geographical variation in the age at which diagnosis is obtained and there are still many late diagnoses (Howlin & Moore, 1997). Early diagnosis is the gateway to understanding the child and beginning to provide the education and support needed. There are two diagnostic systems on which a diagnosis may be based:
