what is pda?

Pathological Demand Avoidance (PDA) is a proposed disorder and sub-type of autism spectrum disorder, defined by characteristics such as a greater refusal to follow the requests of others. PDA is most often seen in people with autism, and it is a pattern of behavior in which kids go to extremes to ignore or avoid anything they perceive as a demand. People with PDA tend to have an adverse reaction to being told how to behave or what to do, even when it’s something that’s an ordinary part of their daily life — and even when it would benefit them. It’s called pathological when the avoidance is extreme and interferes with functioning at home or at school. A PDA profile is also a spectrum and presents differently in different people. Some individuals may have a more externalized or active presentation – where demand avoidance may be overt, physical, aggressive, or controlling. Others have more internalized or passive presentations – where demands may be resisted more quietly, anxiety is internalized, and difficulties are masked. The PDA Society provides information, support, and training about PDA for individuals, families, and professionals.
