Assessment of ADHD in Adults

Differential Diagnosis, Psychometrics and Screening

Workshop Summary

Assessing ADHD in adults can be complex because symptoms such as difficulties with attention, organisation, impulsivity and emotional regulation are common across many mental health conditions. This makes differential diagnosis and considering the whole person key considerations.

This webinar is designed for clinicians who assess for ADHD: psychologists, GPs, psychiatrists and other clinicians who see ADHD or co-occurring issues in their practice.

Dr Tom Mole and Dr Iona Walker will present a practical and systematic approach to adult ADHD assessment from psychiatrists’ and clinical psychologists’ perspectives. The webinar will focus on how standardised questionnaires and psychometric measures can complement the clinical interview and strengthen diagnostic decision-making.

The session will explore the role of screening measures, developmental history, functional impairment and differential diagnosis, including how clinicians can integrate information from multiple sources rather than relying on any single questionnaire or clinical impression.

The webinar will include a formal presentation followed by a facilitated discussion exploring common clinical dilemmas, practical approaches to assessment, and questions from the audience.

Learning Objectives

By the end of this session, participants should be able to:

  • Use psychometric measures appropriately: Understand how standardised questionnaires can contribute to ADHD assessment and where they sit alongside clinical interview and professional judgement.

  • Distinguish screening from diagnosis: Recognise the strengths and limitations of ADHD screening instruments and avoid over-interpreting questionnaire scores.

  • Consider differential diagnosis: Explore how ADHD symptoms can overlap with autism, anxiety, depression, trauma, sleep difficulties, substance use and other neurodevelopmental and psychiatric presentations.

  • Integrate multiple sources of information: Consider how self-report measures, collateral information, developmental history and clinical observations can be brought together to inform diagnostic conclusions.

  • Navigate diagnostic uncertainty: Develop a framework for interpreting conflicting or ambiguous assessment findings and deciding when further assessment may be required.

Session Format

This 90-minute webinar will include approximately 40 minutes of formal presentation, followed by a facilitated clinical discussion and audience Q&A.

The discussion will provide an opportunity to explore practical questions about adult ADHD assessment, psychometrics and differential diagnosis in greater depth.
