Pathological Demand Avoidance (PDA) is a term often used to describe a specific profile within the autism spectrum. PDA autism is characterized by an intense need to resist everyday demands and a preference for feeling in control. While not officially recognized in diagnostic manuals, it is gaining attention among parents, caregivers, and professionals.
Understanding PDA can help create supportive environments for individuals who experience this profile. Exploring its traits, challenges, and strategies sheds light on how PDA intersects with autism and reveals ways to provide effective support.
What is Pathological Demand Avoidance (PDA)?
Pathological Demand Avoidance (PDA) is a profile of autism characterized by an overwhelming need to avoid everyday demands and expectations.
Unlike typical avoidance behaviors, individuals with PDA often use social strategies, such as distraction, negotiation, or withdrawal, to manage these demands.
The underlying cause for this avoidance is said to be a high level of anxiety, usually from expectations of demands being placed on them. This often leads to a feeling of not being in control of a situation.
For those with PDA, even routine tasks can feel overwhelming, leading to heightened stress and a strong drive to resist. Understanding this unique profile can pave the way for more effective approaches to support and care.
Developmental psychologist Elizabeth Newson introduced the term pathological demand avoidance in the 1980s. She observed children with autism-like traits who displayed stronger social skills and significant demand avoidance.
Sometimes referred to as Extreme Demand Avoidance, the PDA profile continues to evolve, though no universally accepted definition exists.
What causes Pathological Demand Avoidance?
While the exact causes of PDA are still being researched, here are some key factors:
- Neurological differences: Like other autism profiles, PDA is linked to differences in how the brain processes information and social cues. This can lead to heightened anxiety and difficulty understanding or responding to demands.
- Sensory sensitivities: Many individuals with PDA also experience sensory sensitivities. Everyday sights, sounds, or textures can be overwhelming, making it harder to cope with demands.
- Anxiety and control: PDA is often linked to high levels of anxiety. Avoiding demands can be a way to feel in control and reduce anxiety.
Symptoms of PDA autism
PDA is thought to be relatively uncommon, and according to Professor Newson’s findings, it is not gender-specific (although there are no prevalent studies).
PDA is often characterized by some of the following:
A resistance or avoidance of the typical demands of life
When a waiter asks, “Would you like something to eat?” most people respond with their choice of meal. For people with PDA, however, this could produce anxiety caused by needing to make a quick decision.
Praise can create pressure to meet higher expectations in the future. External factors like time constraints, uncertainty, social events, or playing a game can contribute to this pressure. Even internal needs, such as eating or sleeping, can trigger these feelings.
This can have the same effect as not wanting to do a chore. The need for control in situations often accompanies these feelings.
It is important to note that someone with PDA might react to a demand in an oppositional way, but they are not defiant, as in the case of Oppositional Defiant Disorder.
For example, not wanting to wear a shirt with a tag could be because of a sensory issue, not deliberate defiance.
Use of social strategies to avoid those demands
To avoid the typical demands of life, these individuals will use some type of social distraction. This can range from making excuses, changing the subject, and procrastinating to running away or aggression.
The reaction can quickly escalate if the person is pushed rather than being allowed to avoid the demand.
Appearance of social ability without social understanding
They may appear to have better conversational skills and social awareness or use more eye contact than others with autism. However, their sense of social identity is often lacking. They struggle to understand how communication works or how to process certain social situations.
This could mean not being able to understand someone’s tone of voice or having trouble processing verbal communication quickly to keep up with a conversation.
Heightened emotions or excessive mood swings
Anxiety often manifests as anger, crying, or other intense emotions. When an individual is unable to label or understand these feelings, it can lead to further confusion and frustration.
The inability to process or cope with these overwhelming emotions can increase distress and make it harder to manage everyday situations.
Comfortability using role or pretend play
Children with PDA often have great imaginations, and many enjoy role-playing or participating in ” dress-up ” activities. For some, though, this can extend to extremes, such as adopting different personas for everyday life to avoid demands.
Obsessive behavior that often focuses on people
Often, a person with PDA has an interest in a particular subject, wanting to know everything they can about that topic. Many times, this interest is in another person, focusing on them to try and know and understand all they can about the person.
This can be difficult in a social setting if a child with a PDA is showing more attention to one child over the others. It can also feel “smothering” to the person receiving all the focus.
PDA vs. autism
It’s easy to get confused between PDA vs. autism in general, as PDA is actually considered a profile within the autism spectrum.
Here’s a simple breakdown of the key differences.
Autism:
- Core features: Difficulties with social communication, repetitive behaviors, and restricted interests.
- Cause of demand avoidance: Although some people may show some resistance to demands, it’s usually linked to sensory overload, difficulty understanding expectations, or a desire for routine.
- Social interaction: Can vary greatly, with some autistic individuals enjoying social interaction and others preferring solitude.
PDA:
- Core feature: Extreme and persistent need to avoid everyday demands, even those they enjoy. This is driven by anxiety and a need to maintain control.
- Demand avoidance: Goes to great lengths to avoid demands, using strategies like meltdowns, distractions, or even manipulation.
- Social interaction: Often appears sociable and engaging, but struggles with the demands that come with social situations.
PDA autism diagnosis
The DSM5 and other diagnostic manuals do not currently include PDA as part of the autism spectrum. However, an initial autism evaluation can be done by a pediatrician or any doctor who provides neurodevelopmental assessments.
Once this is determined, a PDA profile can then be identified. According to the National Autistic Society, UK, this is usually done with assessments from:
- a clinical or educational psychologist,
- a psychiatrist,
- speech/language therapists, and
- occupational therapists (OTs).
Having a specific profile that includes the child’s strengths and specific needs helps ensure the proper support for home, school, and/or work. These can be tailored as the individual’s needs change.
Managing PDA parenting
First, education is key. Parents need to learn as much as they can about PDAs while also considering their child’s personality. There is no “one size fits all” approach.
Because the panda bear is sensitive and needs specific accommodations to survive, the PDA Society has chosen the acronym PANDA to explain how to tailor an approach to this disorder.
The letters stand for the following:
P – Pick Battles
A – Anxiety Management
N – Negotiation and Collaboration
D – Disguise and Manage Demands
A – Adaptation
Pick battles
Many parents have heard this term, and it is important in dealing with a child who feels anxiety when they are not in control of their situation. Understanding that your child is not being willful but is responding to their level of anxiety can help immensely.
Try to focus on your child’s positive qualities rather than on the unwanted behavior. Explaining why something is happening gives the child some perspective and, if possible, allows the child to make choices or control the situation.
Anxiety management
While anxiety is the underlying cause of avoidance and resistance, trying to manage it is important. If a child has social or sensory challenges, be aware of the anxiety that presents with these challenges and plan for it.
Preparing for an early departure from a crowded or loud event or giving a child seamless socks to wear with comfortable shoes might lessen the stress.
Reducing uncertainty can help alleviate that “fear of the unknown.” However, even with the best plan, emotional outbursts may still occur. Handle these like a panic attack, staying calm in the moment and supporting the child throughout the episode.
Negotiation and collaboration
Trust is important in any relationship, but it is essential for children with anxiety about the unknown to trust their caregiver.
It is important for a parent to remain calm while working together with their child to overcome challenges, negotiating an agreement in a fair way.
Disguise and manage demands
This might be as simple as making a game out of an everyday event or working alongside your child to complete a task. It can also be helpful to monitor your child’s capacity for certain demands and keep the demands within that level of tolerance.
Adaptation
Adaptation and flexibility in a variety of situations are key. Allow for extra time and have an alternate plan or a “way out,” such as finding a quiet area in a noisy space.
Finally, distraction, role-play, and even humor can help alleviate tension in a situation. Being silly or asking the child, “How do I do this?” can make the demand seem less daunting.
Supporting children with PDA autism
If a child has autism with a PDA profile, it is important to focus on their positive attributes instead of their challenging behavior. Looking for long-term coping skills rather than a “quick fix” can lead to a more positive outcome over time.
Finally, whatever behaviors the child exhibits, try not to “take it personally.” They are responding to their own anxiety, not responding personally to their caregiver. Parents should find resources for themselves, either in the way of a support group or some self-help.
A parent who is equipped with knowledge and tools can better handle a difficult situation, giving them a better perspective on their child.
