We Offer The Following Psychological Assessments

The ASEBA is a collection of questionnaires which assesses the individual’s adaptive and maladaptive behavior and overall functioning across a range of settings from the perspectives of different informants. For example, for children, the scales are completed by the child, their parent/carer and their teacher. The assessment can be used for clients aged from 1 year 6 months to 90 years old, and typically takes 15 to 20 minutes to complete.

The ADI-R is used for assessment of, and treatment planning for, Autism Spectrum Disorder, and can also help distinguish symptoms of autism from other developmental disorders. The test is based on an interview of the parents or carers of the client, and can be used for children from as young as 2 years old to adults. The ADI-R typically takes 2 hours to complete.

The ADOS-2 is used for the assessment of Autism Spectrum Disorders. Testing is based on observation of the client undertaking tasks in different settings. There are four available modules (one for each age range) including children as young as 12 months, older children, teenagers, and adults. The ADOS-2 takes approximately 2 hours to complete.

CAARS is composed of two ratings (one self-report and one observer scale) focused on identifying symptoms and aiding the assessment of ADHD in adults aged 18 years old and above. The scale typically takes 30 minutes to 1 hour to complete.

CARS is a behavioural rating scale used to assess the symptoms and aid the diagnosis of Autism Spectrum Disorders. The scale can also help differentiate the symptoms of autism from other developmental disorders and is completed by the parent or carer of the child who is more than 2 years old. The scale typically takes 30 minutes to complete.

The Dyslexia Screening Test is used to indicate whether an individual’s symptoms reflect the likelihood of dyslexia without the use of a full diagnostic assessment. The Junior Edition is for use in children aged 6 years 6 months to 11 years 5 months, and the Second Edition is for children aged 11 years 6 months to 16 years 5 months. The test typically takes 30 to 45 minutes to complete.

The test takes approximately 20 to 60 minutes to complete.
