About This Resource
Assessing and Diagnosing OCD: A Clinical Guide
This is a comprehensive clinical reference for identifying and assessing obsessive-compulsive disorder in your practice.
OCD is one of the most frequently misidentified presentations in clinical work. Taboo, harm-related, and scrupulosity presentations in particular are often missed or mislabelled, which means many clients spend years receiving support that does not address what is actually happening for them. Accurate assessment changes that trajectory, and this guide gives you a structured, evidence-based approach to getting it right.
The guide walks you through the clinical features of OCD, the range of presentations described in the literature, structured assessment and validated measures, case formulation using the 5Ps model, and differential diagnosis.
The differential diagnosis content is written from a neurodiversity-affirming framework, recognising that autistic and ADHD clients can and do experience co-occurring OCD, and that the clinical task is understanding what is present for each client rather than simply ruling conditions in or out.
What’s Included
- A clear overview of the clinical features of OCD and the range of presentations described in the literature
- Structured assessment guidance, including validated measures and clinical interviewing approaches
- Case formulation guidance
- A differential diagnosis framework written from a neurodiversity-affirming perspective, including autism and ADHD
Who Is This Resource For?
This resource is designed for psychologists and mental health clinicians who want to assess and diagnose OCD with greater accuracy and confidence.
It is suited to generalist clinicians who encounter OCD across their caseload, as well as those working with neurodivergent clients who want differential diagnosis guidance grounded in neurodiversity-affirming practice.
Whether OCD is a regular part of your work or an area you want to strengthen, this guide gives you a reliable clinical reference to return to across assessment and formulation.

Frequently Asked Questions About the Therapy Tools and Clinical Templates
Are these therapy tools ready to be used in sessions with clients?
Yes. Most of the clinical tools are designed to be used directly in therapy and assessment sessions.
Each therapy manual and guide include structured worksheets, reflection exercises, and homework activities that can be introduced in-session and used between appointments. Printable materials are provided so they can be used collaboratively during sessions or shared with clients for ongoing work.
Where relevant, I have also included guidance for clinicians on how to introduce each tool, explain its purpose, and integrate it meaningfully into therapeutic work. The intention is to support active, collaborative therapeutic processes.
Who are these resources designed for?
These resources are designed primarily for psychologists and allied health professionals working in assessment and therapy settings.
They are used by provisional psychologists, early-career clinicians and more experienced practitioners seeking structured, ethically grounded tools.
Resources within the Understanding Neurodivergence Series are also suitable for neurodivergent community members seeking education and self-reflection.
Can I adapt the templates and tools to suit my own practice style?
Yes. All templates are designed to be flexible.
You are encouraged to adapt language, structure and formatting to suit your theoretical orientation, client population and workplace requirements. They provide a strong foundation while allowing professional judgement to remain central.
Can I share these resources with colleagues or students?
Resources are licensed for individual professional use and are not intended for redistribution or resale. If colleagues or students are interested, please direct them to the website to access their own copies.
Can these clinical tools support autism and ADHD assessment work?
Yes. The diagnostic intake tools and report writing guides are designed to support autism and ADHD assessments across the lifespan.
The intake questionnaires assist with gathering detailed information that standard screening tools often miss. They give clients space to reflect on their experiences before assessment and support the collection of meaningful collateral information where appropriate. This helps streamline your process while maintaining clinical depth.
The report writing templates and guides provide a clear structure for organising findings and communicating diagnostic outcomes respectfully and thoroughly. They are particularly useful for clinicians who want a clear, reliable framework for report writing that can be adapted for each individual client.
All tools are grounded in neurodiversity-affirming practice, supporting strengths-based language and thoughtful formulation. They are designed to support clinical judgement and formal training.
Are these resources suitable for early-career psychologists?
Yes. Many provisional and early-career psychologists use these tools to build confidence in documentation, formulation and intervention planning.
They provide structure without oversimplifying clinical complexity.
Are the NPE practice question modules included in the full NPE course?
Yes. The NPE practice question modules are included in the full version of the NPE preparation course.
They are available separately for those who prefer focused practice questions or who do not intend to purchase the full preparation package.
Do you offer payment plans for your psychology resources?
Flexible payment options are available at checkout through third-party providers such as Afterpay and PayPal, depending on eligibility and provider terms.
Amanda Moses Psychology is not affiliated with these providers. All approvals and payment arrangements are managed directly by the third-party provider.
