Assessment and diagnosis of psychiatric disorder in adults with autism spectrum disorder

Abstract

Purpose

Adults with autism spectrum disorder (ASD) present with a range of psychiatric disorders. However, making an accurate diagnosis is challenging. It is important to follow a robust and informed process in the assessment of psychopathology that is centred on the individual and their neurodevelopmental difficulties. The purpose of this paper is to provide clinicians with an evidence-based approach to the assessment process for adults with ASD presenting with a possible co-occurrent psychiatric disorder.

Design/methodology/approach

A review of the recent literature was undertaken focusing on key papers that describe the assessment of mental health problems in adults with ASD.

Findings

The presentation of psychiatric symptoms is influenced by the underlying developmental disorder and it is often quite different from the one of the general population. Thus, it is essential to undertake a comprehensive psychopathological assessment including a diagnostic assessment of ASD. There is a very small evidence base on the use of diagnostic tools in the assessment of adults with ASD.

Originality/value

This is a practice review paper applying recent evidence from the literature.
