Pathological demand avoidance (PDA) is defined as when an individual goes to great lengths to evade or ignore “demands.” Although PDA is not a formal mental health diagnosis listed in theDiagnostic and Statistical Manual of Mental Disorders, it can cause functional impairment and interfere with an individual’s quality of life.Learn about the signs of PDA, how it develops, and how to support someone who experiences PDA.When Does Demand Avoidance Become Pathological?While everyone is sometimes faced with tasks we would rather not do, for some people, anything seen as a demand or request can be overwhelming. Elizabeth Newson coined the term pathological demand avoidance in 2003 and noted that individuals with pervasive developmental disorders (PDD) tended to exhibit these traits.Since that time, PDD has been reconceptualized as part of theautism spectrum. Although some researchers have suggested that non-autistic people can experience PDA,it seems to be most common in autistic folks.Although PDA can cause functional difficulties, proponents of theneurodiversity-affirming movement have expressed concern that the term tends to, well,pathologizepeople who experience it.Alternative terms proposed include:Extreme demand avoidanceRational demand avoidancePersistent drive for autonomy.Since PDA manifests as ignoring or avoiding requested tasks, it is often misidentified as defiance or oppositionality.Adam Lodestoneshared his experience growing up with misunderstood PDA traits. He also shared that he was assigned female at birth, which likely impacted how his behavior was interpreted in childhood: “When I was a child, I was misdiagnosed with ODD (oppositional defiant disorder] and that framing made me view demand avoidance as a character flaw or some kind of failure on my part to be a ‘good kid.’” Since he preferred to focus on tasks surrounding his interests, Adam struggled with school avoidance and communicating his needs effectively.Elizabeth shared her experience with PDA as well, including noting that although she has had challenges related to her PDA, she also sees it as an asset.That may sound strange because it’s often seen as a ‘downside,’ but for me, it’s been my anchor to my creativity. It gives me courage to listen to my instincts because sometimes I am right. It allows me to understand why someone else may be pressing back hard on me. Once I figured out it was just part of how I worked, non-judgmentally, I started to love it.—ELIZABETH NEWSON, DEVELOPMENTAL PSYCHOLOGISTSigns of Pathological Demand AvoidanceJust like each autistic person is unique and looks different, PDA can manifest in a variety of ways. Traits associated with PDA include:Behavior that appears obsessiveStrong need for control over their environmentMood swingsImpulsive behaviorDifficulty completing non-preferred tasksAvoidance of life demandsSome providers use questionnaires to identify signs of PDA and differentiate it from “defiance” or an impulse control disorder.However, since PDA is a set of traits and behaviors but not a formal diagnosis, limited information about diagnosing or identifying PDA is available.People who experience PDA often do not respond to reward systems in a typical way, meaning thatreinforcingor rewarding “preferred” behaviors and punishing non-preferred behaviors tend to be ineffective in changing behavior patterns.For Elizabeth, PDA manifested as argumentativeness, including finding ways to push back that did not get her into trouble: “I can’t tell you if I ever had any good arguments, but I can tell you I was and am persistent when I want something and this led to me wearing down adults during conflict. I also learned early [that] keeping a calm demeanor meant I could be much more defiant without punishment.”She additionally attributed some rule-breaking and rebellious behavior to PDA: “In high school, my antics got a little more out of hand. We broke into an abandoned building to play with the equipment left behind. We replaced the school office waiting room magazines with inappropriate materials.

For children, demand avoidance that is misinterpreted as “defiant” behavior can lead to punishment or being labeled as a “problem.” When adults label children’s behavior as “bad” or “naughty,” children might internalize this message, impacting their mental health andself-esteem. For Adam, “I definitely grew up believing that I was ‘bad,’ ‘willful,’ ‘defiant,’ ‘lazy,’ and ‘a brat.’”PDA can also impact learning. According to Elizabeth, “Despite being smart and able to perform very well on tests, I didn’t do any work I didn’t find important, regardless of how important my teacher or professor saw it or how much it mattered to my grade. I also attended school for the bare minimum of required instructional hours and missed a lot of educational time.”In adulthood, Adam said that PDA traits have made employment challenging: “In my 20s, my demand avoidance impacted how I related to my co-workers and managers, and it would eventually cause me to abruptlyquit jobs, often leaving me in a financial crisis.”Living With Pathological Demand AvoidanceSince PDA presents differently for different people, approaches to cope with difficulties related to PDA vary.

Elizabeth shared, “Let me go. Let me fizzle out or amp up or do my own thing. And don’t take it personally; assume the best intentions, and I’ll often prove you right.”In fact, shaming people with PDA and trying to force them to comply can often backfire.
