PDA – the basics

This self-paced, interactive module offers a clear and accessible introduction to Pathological Demand Avoidance (PDA), a profile on the autism spectrum. Whether you’re a parent, carer, professional, or PDAer yourself, this course provides a compassionate and practical foundation for understanding PDA.

The module explores:

• what PDA means
• the history of PDA
• how to recognise PDA
• why learning about PDA is helpful

This module was developed by the PDA Society with input from PDAers, families, and professionals, combining lived experience with up-to-date knowledge.

Course information

Our self paced learning modules are designed to make learning simple, flexible, and engaging. Unlike a traditional PDF or webinar, these courses are:

• Interactive – with click-through activities, videos, and knowledge checks to keep you involved.

• Self-paced – you can start and stop whenever you like.

• Accessible anywhere – available on desktop, tablet, or mobile* so you can learn in the way that works best for you.

• Visually engaging – designed with clear layouts, easy navigation, and bite-sized sections that are quick to work through.

• Practical and supportive – each module focuses on real-world examples and approaches you can apply straight away.

Our modules feel more like an interactive guide than a lecture — putting you in control of your own learning journey.

*You can access this module on any device — desktop, tablet, or mobile. For the smoothest experience we recommend using a desktop.
