PDA and Demand Avoidance in Children and Young People: Looking Beyond the Behaviour
PDA, usually understood to mean Pathological Demand Avoidance, describes a pattern in which everyday demands and expectations are met with a powerful need to resist, avoid or regain control. The term is most often associated with autism, and sometimes with other forms of neurodivergence, although demand avoidance is by no means exclusive to neurodivergent children and young people.
For some families, recognising PDA in children and young people can provide an important way of understanding behaviour that has previously seemed baffling. A child who has been described as difficult, oppositional or controlling can begin to be understood differently. The idea of demand avoidance can also help parents and professionals recognise that behaviour which appears deliberately defiant may arise from a young person's experience of demands, control and autonomy.
PDA is also a contested concept. It is not a standalone diagnosis in the major diagnostic manuals, there is continuing debate about exactly what it describes and its relationship with autism and other forms of neurodivergence, and even its name remains controversial. This uncertainty does not make the idea unhelpful, but it does invite us to think carefully about what we mean when we describe a child or young person as having a "PDA profile".
Where Did the Idea of PDA Come From?
The term Pathological Demand Avoidance was developed by Professor Elizabeth Newson, a developmental psychologist at the University of Nottingham. During the 1980s, Newson became interested in a group of children referred for assessment who shared characteristics with autistic children but did not fit comfortably with how autism was understood at the time.
Newson and her colleagues eventually described the central feature they observed as an "obsessional avoidance of the ordinary demands of everyday life" (Newson, Le Maréchal & David, 2003). Their observations were brought together in a 2003 academic paper proposing PDA as a separate syndrome within what were then known as the pervasive developmental disorders.
Our understanding and classification of autism has changed considerably since Newson began this work. PDA did not become a separate diagnostic category and is not a standalone diagnosis in either the DSM or ICD psychiatric manuals. It is now more commonly described as a profile, particularly in discussions of autism and neurodivergence, although its status and boundaries continue to be debated.
This history matters because something that began as a description of a particular group of children's behaviour can easily acquire the authority of a diagnosis. Saying that a child "has PDA" can bring relief and recognition, but it can also begin to sound as though something fixed has been discovered inside them which explains their behaviour.
What Does a PDA Profile Explain?
Describing PDA as a profile rather than a diagnosis is an important distinction. A profile identifies a pattern, particularly around demands, avoidance and the need for autonomy. It can help us recognise that a child's refusal is not adequately explained by laziness, deliberate disobedience or poor parenting. Yet identifying the pattern does not tell us why it is happening.
This becomes particularly interesting when we consider what we actually call PDA. A young autistic child who screams, lashes out or has a meltdown when faced with everyday demands might have their behaviour understood as part of a PDA profile. A child without an autism diagnosis who refuses to enter school might instead prompt questions about anxiety, relationships, bullying, family life or what has happened at school. As the young person grows older, similar acts of refusal may acquire different names again, including school avoidance, anxiety, disengagement or difficulties with education and employment.
These experiences are not equivalent, and PDA describes a broader pattern than any single act of refusal. There is nevertheless an important question here. Why should identifying a young person as autistic make us less curious about the individual meaning of their behaviour?
Autistic people are no less individual than anyone else. Autism can help us understand important aspects of how somebody experiences and responds to the world, but it cannot tell us what a particular experience means to them. In the same way, identifying a PDA profile can provide a useful framework without explaining why this child needs to refuse this demand, from this person, in this situation.
Looking beyond the behaviour is therefore not an argument against recognising PDA, autism or neurodivergence. It is an argument for refusing to let a profile replace the person it was intended to help us understand.
Pathological Demand Avoidance or Persistent Drive for Autonomy?
The word pathological has itself become controversial. An alternative formulation increasingly encountered is Persistent Drive for Autonomy. The initials remain PDA, but the change in language alters where we place our attention.
Pathological Demand Avoidance begins with what other people encounter: a person who repeatedly avoids demands. Persistent Drive for Autonomy turns our attention towards what the person might be attempting to preserve. Rather than asking how to overcome the avoidance, we can ask why autonomy, agency and the ability to influence what happens have become so important.
This shift is useful beyond PDA. Whether a young person is autistic, otherwise neurodivergent or neurotypical, behaviour takes place within their history, relationships and experience of the world. A refusal has a context and can serve a function, even when neither the young person nor the adults around them yet understand what that function is.
Understanding "No"
At the centre of PDA is refusal. In its clearest form this is the word "no", but refusal does not always arrive in words. It might appear in a meltdown, running away, lashing out, becoming silent or refusing to engage. As children move through adolescence and towards adulthood, refusal can become less immediately visible, appearing through not attending, withdrawing or finding ways to escape situations in which demands have become difficult to tolerate.
None of these behaviours in themselves establish a PDA profile. They do, however, draw our attention to something fundamental about refusal: there must be something to refuse. A "no" only makes sense in relation to something that is being experienced as a demand.
This brings relationship and context into the centre of our understanding. If somebody says no, we also need to become interested in what they are saying no to.
Where Do Demands Come From?
The most obvious demand comes from another person. A parent says that it is time to get dressed, a teacher asks for a piece of work or somebody expects an answer to a question. In each case, something is being asked of the young person by somebody else.
Demands can also be embedded within institutions. A school does not have to speak to make demands. Its timetable, uniform, rules and expectations establish what a child must do and when they must do it. University and employment introduce different structures as the young person grows older, while wider society contains rules, laws and expectations about behaviour and independence.
Even the body makes demands. Hunger, tiredness and the need to use the toilet impose requirements that cannot always be negotiated away. For someone whose experience of demands has become closely bound to autonomy and control, eating, sleeping, washing or toileting can also become areas of difficulty.
Thinking about demands in this broader way moves us beyond asking why a child will not do what they have been told. We can begin to investigate what happens for this particular person when somebody or something imposes a requirement upon them.
PDA, Neurodivergence and Trauma
PDA has its historical roots in attempts to understand a particular group of autistic children and remains most strongly associated with autism. It is nevertheless important not to make autism itself the explanation for an individual's refusal. Autistic and other neurodivergent young people have their own histories, relationships and ways of experiencing other people and the world around them.
Trauma adds another dimension to this without providing a competing explanation for PDA. Trauma can be understood as an experience of unwanted overwhelm in which a person's available means of coping are exceeded. It often involves a profound loss of agency: something happens to the person that they cannot control, escape or adequately respond to.
In this sense, the person can experience themselves as subject to somebody or something else's will. What they want is no longer able to alter what happens next. For someone who has experienced the world in this way, maintaining control can acquire an important protective function. The determination that you will not decide what happens to me can defend against the possibility of once again becoming powerless in the face of what another person or situation demands.
This does not mean that trauma causes PDA, or that demand avoidance indicates a history of trauma. It demonstrates why the meaning of autonomy cannot be assumed from the profile alone. Within the broad context of autism, other forms of neurodivergence and individual developmental experience, the question remains: why has maintaining autonomy become so important to this particular young person?
Beyond Managing PDA
Practical approaches to PDA can be helpful, particularly when they reduce unnecessary demands, allow greater flexibility and move away from escalating struggles over control. Understanding that a child is struggling with the experience of a demand rather than deliberately trying to make life difficult can itself change relationships within families and schools.
The difficulty comes when management becomes the whole response. The young person can become surrounded by increasingly sophisticated strategies for presenting demands in ways that produce cooperation, while little attention is given to why demands are so difficult in the first place. There is a risk that the profile intended to produce greater understanding instead becomes another way of locating the problem within the child.
Looking beyond behaviour does not mean abandoning practical strategies or expecting every refusal to reveal a hidden psychological explanation. It means keeping open the possibility of understanding the person as well as responding to the immediate difficulty. This matters for autistic and neurotypical young people alike. The presence of a neurodevelopmental diagnosis should not determine whether we become curious about an individual's experience.
Persistent Drive for Autonomy offers a useful route into this curiosity. If maintaining autonomy serves an important function, then the task is not confined to finding better ways of getting around the refusal. We can become interested in what the young person is protecting, how they experience the expectations of other people and whether their need for control allows them to feel safer in a world that can otherwise feel intrusive, overwhelming or unpredictable.
This movement from managing behaviour towards understanding the individual is where psychotherapy can offer a different approach.
PDA and Psychoanalytic Psychotherapy
Psychoanalytic psychotherapy does not begin from the assumption that demand avoidance is a behaviour that needs to be removed. Therapist and young person can explore what refusal means, what function it serves and the circumstances in which autonomy becomes particularly important.
The young person's history forms part of this work. Their experiences within their family, friendships, education and wider world matter, alongside their experience of neurodivergence and any history of feeling overwhelmed, misunderstood or controlled. The aim is not to search backwards until an event can be identified as the "cause" of PDA. It is to understand how this particular person has come to experience themselves, other people and what is asked of them.
The therapeutic relationship is particularly important because psychotherapy cannot position itself outside the problem of demands. Therapy has an appointment time, a room or online meeting and another person who is interested in the young person. The therapist may ask a question, while parents or professionals may hope that therapy will produce change. Even an invitation to talk can contain an expectation.
A young person's refusal does not therefore have to be regarded as something preventing therapy from taking place. It can become part of the work itself. What happens when the young person disagrees, refuses to answer or tells the therapist that they have got something wrong? Can another person remain interested without taking control or determining what the young person should think, feel or become?
Through the relationship, therapist and young person can begin to understand what is happening without demanding that it change first.
Finding Ways Forward
The aim of psychotherapy is not to replace a young person's "no" with an obedient "yes". Being able to refuse is an important part of autonomy, and children, teenagers and young adults need to be able to communicate when something is unwanted, intolerable or wrong for them.
The difficulty arises when protecting autonomy becomes so necessary that refusal begins to restrict the person's freedom. Education, friendships, relationships, employment and increasing independence all involve encounters with other people's wishes and with demands that cannot always be avoided. The need to remain in control can itself begin to narrow what becomes possible.
Psychotherapy provides somewhere this can be explored without beginning from a demand for compliance. Understanding the meaning, history and function of refusal can allow therapist and young person to work together towards different ways of responding to demands and relationships, while respecting the importance autonomy has held for them.
PDA can give us a useful name for a recognisable pattern, while Persistent Drive for Autonomy encourages us to ask what might lie behind that pattern. Neither tells us who the individual is or why their "no" has become necessary. Looking beyond the behaviour means retaining our curiosity about the individual, whether they are autistic, otherwise neurodivergent or neurotypical.
That is where understanding begins.
