A clinical assessment for ASD typically involves a one-on-one review, interviews with parents, carers, or family members as appropriate, and obtaining collateral information from others who know the individual well or have worked closely with them. This process can involve multiple sessions and usually includes the use of a structured assessment tool, such as the ADI-R or ADOS. Additionally, reports from other specialists, such as a functional assessment, may be included at the clinical discretion of the assessing psychiatrist.
The final session of the assessment process often involves providing feedback, clinical opinions, and recommendations. This session also allows the individual and their family or carers to ask questions. Following the assessment, a letter is sent to the GP or referrer, as applicable.
