What is PDA?

---

If you've found your way here, it is likely that you have heard the term Pathological Demand Avoidance/Persistent Drive for Autonomy (PDA). Although we are still in the earlier stages of research and recognition, PDA is gaining increasing awareness and legitimacy. What is important to know about PDA is that it is currently understood to be a profile on the autism spectrum, and that there are a cluster of characteristics that people with a PDA profile share. Most notable, is an extreme avoidance of routine, everyday demands. 

We also know that PDA is often missed or misdiagnosed, which increases risk factors associated with PDA, such as issues around access to education, burnout, anxiety, and other mental health concerns. While I am eager for growing research and PDA awareness,  we don't need to wait to start providing meaningful support. We already know that there are adults, children, and families that feel best understood through a PDA lens, and that have felt supported by an approach developed from this understanding.

A PDA profile of autism means that individuals share autistic characteristics …

• persistent difficulties with social communication and social interaction,” and, “restricted and repetitive patterns of behavior, activities or interests,” present since early childhood to the extent that these, “limit and impair everyday functioning,” (according to the Diagnostic and Statistical Manual Fifth Edition, DSM-5)
• often including a different sensory experience in relation to sight, smell, taste, touch, hearing, vestibular, proprioception and interoception.

… and also:

• have a need for control which is anxiety related
• are driven to avoid everyday demands and expectations (including things that they want to do or enjoy) to an extreme extent
• tend to use approaches that are ‘social in nature’ in order to avoid demands
• present with many of the ‘key features’ of PDA rather than just one or two
• tend not to respond to conventional parenting, teaching or support approaches
