Positive Behaviour Support for PDA
​(Pathological Demand Avoidance)

Understanding PDA and Behaviour

Children with PDA often experience high levels of anxiety related to everyday demands. Behaviour such as avoidance, refusal, negotiation or emotional outbursts is often a response to feeling overwhelmed rather than intentional defiance.

​Positive Behaviour Support focuses on understanding:
  • Why behaviours are happening
  • What triggers anxiety and demand avoidance
  • How environments and expectations can be adjusted
  • How to build skills for regulation and participation
What is Positive Behaviour Support (PBS)?

Positive Behaviour Support is an evidence-informed approach that focuses on improving quality of life by understanding behaviour and teaching new skills.

​Rather than focusing on “managing behaviour,” PBS looks at:
  • The purpose of behaviour
  • Environmental and emotional factors
  • Skill development
  • Long-term, meaningful outcomes
​How PBS Supports Children with PDA

​PBS is particularly well suited to PDA because it focuses on reducing pressure, understanding behaviour and building trust.

​Support may include:
  • Identifying triggers and reducing demand-related anxiety
  • Developing low-demand, flexible approaches
  • Supporting emotional regulation and coping strategies
  • Creating consistent strategies across home and school
  • Building tolerance for everyday expectations over time

PDA Strategies for Home and School

Supporting a child with Pathological Demand Avoidance (PDA) often requires a flexible, collaborative approach that focuses on reducing anxiety, building trust and supporting emotional regulation.

Every child is different, and strategies should be tailored to the child's individual strengths, preferences and support needs.

PDA and Anxiety
Many professionals believe that anxiety plays a significant role in PDA.

For some children, everyday expectations can trigger feelings of overwhelm, uncertainty or a loss of control. When anxiety increases, the child may avoid, negotiate, distract, withdraw or become highly distressed when faced with demands.

Rather than viewing these behaviours as intentional defiance, it can be helpful to consider the anxiety and stress that may be sitting underneath the behaviour.

Reducing anxiety often helps improve participation more effectively than increasing pressure, consequences or repeated instructions.

Why Demands Feel Overwhelming
Demands are not limited to instructions from adults.
Children with PDA may experience pressure from:
  • School expectations
  • Social situations
  • Daily routines
  • Time pressures
  • Transitions
  • Sensory environments
  • Self-imposed expectations
Even activities a child normally enjoys can become difficult if they begin to feel like an expectation rather than a choice.
Understanding how demands affect the individual child can help families, schools and support teams develop more effective strategies.

Low-Demand Approaches
Many families find that reducing unnecessary demands can lower anxiety and improve engagement.
Examples may include:
  • Offering choices rather than direct instructions
  • Using indirect language
  • Incorporating humour and playfulness
  • Reducing time pressure
  • Allowing flexibility where appropriate
  • Breaking larger tasks into smaller steps
The goal is not to remove all expectations, but to present them in ways that feel safer and more manageable.

Collaborative Problem-Solving
Children with PDA often respond well when they feel involved in decisions that affect them.
Collaborative problem-solving may involve:
  • Asking for the child's ideas
  • Exploring challenges together
  • Negotiating solutions
  • Identifying barriers
  • Creating shared goals
This approach helps reduce power struggles while building trust, autonomy and engagement.

PDA at School
School environments can be particularly challenging because they often involve frequent demands, transitions, social expectations and structured routines.
Some children may experience:
  • School refusal
  • Difficulty completing work
  • Avoidance of classroom activities
  • Anxiety about attendance
  • Emotional outbursts
  • Challenges with transitions
Supporting a child at school often involves collaboration between families, teachers and allied health professionals to develop practical strategies that reduce anxiety and support participation.

Supporting Emotional Regulation
Emotional regulation is often an important focus for children with PDA.
Helpful strategies may include:
  • Co-regulation with trusted adults
  • Predictable routines
  • Sensory supports
  • Visual supports
  • Calm environments
  • Emotional coaching
  • Movement and regulation breaks
When children feel emotionally safe and regulated, they are often better able to cope with everyday expectations and challenges.
​
Can Children with PDA Thrive?
Children who display PDA traits often have many strengths, including creativity, humour, problem-solving abilities, strong interests and unique ways of thinking.

With supportive environments, understanding adults and appropriate strategies, many children are able to build confidence, participate in learning, develop meaningful relationships and achieve their personal goals.
​
The focus should not be on changing who the child is, but on understanding their needs and helping them navigate everyday life in ways that feel safe, respectful and achievable.
