In carrying out an assessment for an adult I use the DSM_5 and ICD-11 diagnostic criteria. The assessment is combined with a developmental history based on elements from the Autism Diagnostic Interview (ADI-R) and over twenty-five years’ experience. The assessment follows all diagnostic criteria from the International Classification of Diseases (ICD-11) and the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The assessment gathers detailed information in order to fully inform a diagnostic decision with no further assessment being necessary. In doing this assessment, I will look at your developmental history and current situation to understand your thinking and personality style. We will then discuss how these have impacted on your life, and what changes may be relevant for the future. It may be useful to include someone who knows you well in the interview, such as a parent or spouse, although this is not compulsory.

​

If further information were required, I am also trained in using the Autism Diagnostic Interview - Revised (ADI-R) and the 3Di, developmental interviews which also consider a range of differential diagnoses. I may also carry out the Autism Diagnostic Observation Schedule – Revised (ADOS-R), in those cases when more evidence is required, although this is rarely required.

​

The initial assessment takes around 2½ - 3 hours to administer. The assessment is conducted in a clinic in Woking, Surrey or online using Zoom or the platform of your choice. Following assessment, a full report with formulation of any associated psychological difficulties and recommendations is compiled. The cost of this assessment and extensive report is £900.

​

A further feedback and planning session can be arranged at a further cost of £120 per hour.
