Pathological Demand Avoidance (Pda) in Children: a Comprehensive Neurodiversity-Affirming Guide
Understanding Pathological Demand Avoidance
What Is Pda?
Pathological demand avoidance (PDA) is a Neurodevelopmental conditions characterized by extreme Anxiety-driven avoidance of everyday demands and expectations. First identified by Professor Elizabeth Newson in the 1980s, PDA is increasingly recognized as a distinct profile within the autism spectrum. Unlike typical oppositional behavior, PDA involves an automatic stress response triggered by perceived loss of control rather than deliberate defiance.
The core mechanism of PDA is Anxiety about control—not opposition to specific activities. Children with PDA cannot comply when they perceive loss of control, even when strongly motivated to do so. A child who desperately wants to go to the park but cannot put on shoes when told to do so will miss the outing entirely, demonstrating that resistance isn’t about the activity but about maintaining autonomy.
The Nature of Demands in Pda
In PDA, a “demand” extends far beyond direct requests and includes:
- Direct instructions and suggestions
- Questions (even “How are you?”)
- Expectations and praise
- Indirect demands like hunger or fatigue cues
- Environmental expectations
- Self-imposed demands and internal expectations
- Social obligations and conversational turns
The resistance is pervasive across all life areas, even affecting preferred activities. This distinguishes PDA from typical Demand avoidance—children with PDA will avoid activities they genuinely want to do if someone else initiates them.
Neurological Basis
PDA operates through the same stress response system that produces trauma symptoms. When children with PDA perceive loss of control, their nervous system automatically enters fight, flight, or freeze mode. This response is not within conscious control—it’s a neurologically driven adaptive reaction to perceived threat.
Research suggests PDA brains may be structurally hypersensitive to environmental threat, making individuals more susceptible to toxic stress and adverse childhood experiences. This Neurological difference justifies trauma-informed approaches as essential rather than merely helpful.
Clinical Features of Pda
Core Characteristics
Resistance and Avoidance of Ordinary Demands Children engage in excessive, persistent resistance using negotiation, distraction, social manipulation, claimed incapacity (“my legs don’t work”), or intense arguing. Resistance depends on Anxiety levels—sometimes children can push through demands, other times they cannot. The effort expended is described as “pathological” because it exceeds typical childhood resistance.
Surface Sociability Without Social Depth PDA presents a paradox where children often appear more socially motivated than classically Autistic peers. However, significant gaps exist in:
- Following multi-person conversations due to processing speed issues
- Understanding reciprocal friendship and social boundaries
- Recognizing social hierarchy (treating all people as equals)
- Reading subtle social cues and Body language
- Considering how actions impact others’ feelings
Excessive Mood Swings and Impulsivity Due to constant hypervigilance and Anxiety, children struggle with Emotional regulation. Mood changes can appear unpredictable or triggered. The impulsivity stems from automatic threat-reduction responses rather than conscious decision-making. This can manifest as compulsive persistence in prohibited behaviors—the more told not to do something, the more compelled to continue.
Comfortable in Role-Play and Pretending Children with PDA display exceptional creativity and imaginative skills, using role-play to:
- Avoid demands and control situations
- Resist direction while participating in Anxiety-provoking activities
- Explore concepts safely within imagination
- Mask discomfort by becoming the “perfect student”
Language Development Patterns Many children show early language delay followed by significant catch-up in toddlerhood and preschool years. This differs from typical autism patterns where language gaps may persist.
Obsessive Behavior Often Directed at People Unlike typical Autism’s object or topic focus, PDA obsessions often center on specific people, creating relationship challenges. When focused on a parent, the child insists that parent handle all care activities, exhausting that parent and potentially alienating the other parent.
Associated Characteristics
- Low self-esteem and self-confidence: By school age, many internalize messages of being “naughty” or “difficult”
- Threats of violence or obscene language: Often “limbic utterances”—stress responses rather than conscious choices
- Executive functioning difficulties: Affecting memory, attention, organization, and task initiation
- Trauma susceptibility: Due to Neurological differences and misunderstanding of behavior
Why Traditional Approaches Fail
The Demand Problem in Traditional Therapy
Traditional Therapy typically involves:
- Clinician-directed activities and topics
- Expectation of reflection and discussion
- Explicit and implicit behavioral expectations
- Reward and consequence systems
While effective for many children, these approaches escalate Anxiety and trigger Demand avoidance in PDA because:
Automatic Expectation of Compliance Many professionals assume children should automatically respect authority. Children with PDA don’t recognize social hierarchy and won’t comply due to adult status. Authoritative responses trigger increased Anxiety and avoidance.
Clinician-Led Sessions When clinicians direct activities and structure, they remove control from the child, triggering Anxiety. Even incorporating special interests can trigger avoidance if adult-suggested.
Sessions Contain Numerous Demands A standard first session contains multiple explicit and implied demands:
- “Come in”
- “Sit down”
- “How are you?”
- “What would you like to do?”
- Waiting room expectations
- Attendance itself
Reward and Consequence System Issues These systems assume conscious control over behavior, which isn’t true for Anxiety-driven Demand avoidance. Rewards can themselves be perceived as demands and create ongoing performance pressure.
Understanding the Compliance Paradox
The fundamental misunderstanding is viewing PDA as behavioral opposition rather than Neurological Anxiety. Traditional approaches that “work” for oppositional behavior often backfire catastrophically with PDA because they increase the very Anxiety driving the avoidance.
Trauma-informed Approach to Pda
Brain Development and Stress Response
Early brain development follows a bottom-up sequence:
- Brainstem (automatic functions, fight/flight/freeze)
- Limbic System (attachment, Emotional regulation, relationships)
- Cerebral Cortex (higher-order thinking, reasoning)
Brain development depends on experience—stable, nurturing relationships create healthy brain circuitry. When children feel safe, the brain shifts from “survival mode” to connection and higher functioning.
Trauma-Informed Principles
Safety
- Physically, emotionally, and relationally safe spaces
- Consider the child’s perception of safety, not just adult perception
- Adapt environment to prevent rule-breaking rather than creating rules
- Understand the window of tolerance—smaller for those with trauma or PDA
Trustworthiness
- Show reliability, consistency, and compassionate responses
- Keep promises and respect negotiated boundaries
- Children with PDA have exceptional memories for unkept promises
- Consistency and calm responses demonstrate stability
Choice
- Options provide perception of control and reduce vulnerability
- Limit choices to 2-3 options with time for decision-making
- Removing demands paradoxically increases engagement
- Genuine autonomy leads to more openness to suggestions
Collaboration
- Work from equality where each person has something to offer
- Involve individuals in decisions affecting them
- Listen to and consider thoughts and feelings before addressing problems
- Use problem-solving rather than confrontation when demands cannot be removed
Empowerment
- Use strengths-based approaches identifying and building on personal resources
- Support children to take the lead and recognize their words have power
- Build confidence for self-help and seeking Support when needed
- Focus on what children can do, not limitations
The “regulate, Relate, Reason” Sequence
Developed by Dr. Bruce Perry, this represents brain development sequencing:
Regulate Support optimal stimulation through:
- Repetitive, rhythmic activities (walking, dancing, drumming, rocking)
- Proprioceptive activities (pressure on joints, lifting, climbing)
- Oral stimulation (straws, bubbles, chewing)
- Make various regulating activities available for child choice
- Match child’s energy level then gradually de-escalate
Relate
- Strong, nurturing relationships are essential for healing and Therapy success
- Prioritize trusting therapeutic relationships early in Therapy
- Connection supports brain integration for optimal learning state
- More important than any specific technique
- Consistent, compassionate adults who show children they are safe and accepted
Reason
- Once feeling safe and connected with better brain integration
- Children can engage higher-order thinking and reasoning
- Reflect on thoughts, feelings, and experiences
- Communicate clearly and learn about themselves and others
- Make conscious decisions about emotional responses and behavior
Beginning Therapy with Pda Children
Intake Information Gathering
Essential Information to Collect:
- Sensory sensitivities (aversive versus calming input)
- Special interests and motivations
- Specific Anxiety triggers and challenging behaviors
- Signs of stress or agitation (subtle indicators)
- What calms or regulates the child
- Child’s strengths and positive attributes
- Parents’ journey to Diagnosis without judgment
First Session Preparation
Provide Advance Information
- Explain session format through parents
- Reduce anticipatory Anxiety by creating inviting picture
- Emphasize choice and control over activities
Adapt to Child’s Needs
- Be prepared for any reaction, including refusal to enter
- Parent may need to remain in sessions initially
- Sessions may need to be shorter than standard 50-60 minutes
- Allow time in hallway or waiting area if needed
Give Permission to Observe
- Resist trained urge to “do” Therapy immediately
- Be comfortable with silence and exploration time
- Note what child is drawn to and discusses
- Don’t force talk or answer demands
Communicate Therapy Role Establish clear Therapy rules focused on safety and trust:
- You can tell me anything
- I will never get angry or upset
- I won’t think problems or concerns are silly
- You can’t get in trouble in my room
- Parents can’t tell you off for things you tell me
- I don’t tell anyone what we talk about unless worried about safety
Set Minimal Boundaries
- Keep overall limits minimal to avoid overwhelming
- Focus on safety: “We both need to feel safe”
- Frame boundaries around safety, not behavior
- Example: Complete freedom with safety limitations
Practical Therapeutic Strategies
Using Indirect Language
Direct instructions trigger Anxiety and refusal. Instead use:
- “I wonder…”
- “I bet you can’t…”
- “I just noticed…”
- “I can’t figure out how to do this—do you know?”
Non-verbal indirect approaches:
- Place activities visibly without drawing attention
- Shift focus away from child to siblings, parents, or characters
- Read to teddy bears while child plays elsewhere
- Use puppets and toys as communication intermediaries
When necessary to set boundaries, deflect responsibility to external authorities (“The law says…”, “My boss requires…”) rather than personal rules.
