Autism Diagnostic Assessments for Adults

During this stage of the assessment we will ask you to complete some questionnaires.

The questionnaires that we use are validated tools that are used internationally to assist in the screening and diagnosis of autism such as:

Autism Quotient (AQ)

The Autism-Spectrum Quotient Test (AQ)is a diagnostic questionnaire designed to measure the expression of Autism-Spectrum traits in an individual, by his or her own subjective self-assessment.

Empathy Quotient (EQ)

The Empathy Quotient (EQ) is a questionnaire designed to measure empathy in adults.

Childhood Autism Spectrum Test (CAST)

The Childhood Autism Spectrum Test (CAST) is a questionnaire aimed at parents for assessing autism symptoms. At this stage we will also gather relevant personal information such as family background and medical history. We will ask you to share any relevant reports you have with us. We will also seek information your child’s early years setting, school or college.

Camouflaging Autistic Traits Questionnaire (CAT-Q)

The Camouflaging Autistic Traits Questionnaire (CAT-Q) is a self-report measure of social camouflaging behaviours in adults. It is used to help clinicians understand if the individual is masking their autistic traits.

At this stage we will also gather relevant personal information such as family background and medical history. We will ask you to share any relevant reports you have with us.

At the assessment stage we will complete two formal assessments. One will be a direct observation with yourself called the ADOS – 2. The second assessment will be to gather information about your childhood. We can either do this by interviewing someone who knew you well as a child using the ADI-r or by arranging a second interview with yourself using the RAADS- r or ACIA.

Autism Diagnostic Observation Schedule -Second Edition (ADOS 2)

The ADOS-2 is a semi-structured, standardised assessment of communication, social interaction, play, and restricted and repetitive behaviours. It presents various activities that elicit behaviours directly related to a diagnosis of ASD. By observing and coding these behaviours we can obtain information that informs diagnosis.

Autism Diagnostic Interview-Revised (ADI-R)

The ADI-R is one of the most widely used diagnostic algorithms in determining whether or not someone has autism spectrum disorder (ASD). The ADI-R does not directly involve the child or teenager being assessed; it is an interview conducted with the parents. In certain circumstances the interview can be conducted with someone else who knows the child very well to gather information.

Ritvo Autism Asperger Diagnostic Scale – Revised (RAADS–R)

The RAADS–R is an 80-item clinician-administered questionnaire designed to identify adults with Autism. The questionnaire covers the range of behaviours that are characteristic of autism and is administered in the form of an interview with one of our clinicians.

ACIA

The Autism Clinical Interview for Adults (ACIA) is a semi-structured interview designed for use in both clinical and research settings, as part of a multi-disciplinary diagnostic assessment for adults aged 16 years of above with a possible autism spectrum disorder (ASD). The interview provides a framework for a developmental history and is designed to be conducted with the individual themselves.

When we have gathered the information our multi-disciplinary team will review it and decide whether your meet the DSM 5 criteria for a diagnosis of autism spectrum disorder.

The DSM 5 (Diagnostic and Statistical Manual of Mental Disorders) is the handbook used by health care professionals across much of the world as the authoritative guide to the diagnosis of mental health issues and neurodevelopmental conditions. The DSM contains descriptions, symptoms and other criteria for diagnosing these conditions, ensuring a standardised approach to diagnosis.

The DSM 5 criteria for autism spectrum disorder are:

A. Persistent deficits in social communication and social interaction across multiple contexts, as manifested by all of the following, currently or by history:

1. Deficits in social-emotional reciprocity
2. Deficits in nonverbal communicative behaviours used for social interaction
3. Deficits in developing, maintaining, and understanding relationships

B. Restricted, repetitive patterns of behaviour, interests, or activities, as manifested by at least two of the following, currently or by history:

1. Stereotyped or repetitive motor movements, use of objects, or speech
2. Insistence on sameness, inflexible adherence to routines, or ritualized patterns of verbal or nonverbal behaviour
3. Highly restricted, fixated interests that are abnormal in intensity or focus
4. Hyper- or hypo reactivity to sensory input or unusual interest in sensory aspects of the environment

C. Symptoms must be present in the early developmental period (but may not become fully manifest until social demands exceed limited capacities, or may be masked by learned strategies in later life) (Must be met)

D. Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning (Must be met)

E. These disturbances are not better explained by intellectual disability (intellectual developmental disorder) or global developmental delay (Must be met)

When we have reached our diagnostic conclusion we will arrange a feedback meeting with you. During the feedback meeting one of our clinicians will explain the diagnostic outcome and the reasons for this. The clinician will provide advice on any presenting issues and next steps and answer any questions. A detailed report of our findings which summarises all the information gathered will be provided.
