In carrying out an assessment for an adult I use DSM-5 autism diagnostic criteria, combined with a Developmental History based on elements from the Autism Diagnostic Interview (ADI-R) and twenty five years’ experience. The assessment also considers follows all diagnostic criteria from the International Classification of Diseases (ICD-10). This assessment generally gathers adequate 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 can be useful to include someone who knows you well in the interview, such as a parent or spouse, if you chose to include a familiar person. However, this is not essential for the process.
