PDA (Pathological Demand Avoidance) and ODD (Oppositional Defiant Disorder)

 

are both behavioural conditions often associated with children, though they can also persist into adulthood. They have distinct characteristics but can sometimes be confused due to overlapping traits.

​

PDA (Pathological Demand Avoidance)

PDA is a profile of Autism Spectrum Condition (ASC), characterized by an extreme avoidance of everyday demands and expectations due to anxiety and a need for control. Individuals with PDA often feel overwhelmed by even minor requests, leading them to resist or avoid demands in creative and sometimes socially challenging ways.

Key Characteristics of PDA:

• Demand avoidance: A strong, often overwhelming need to avoid demands placed by others, even those the individual places on themselves.

• High levels of anxiety: The avoidance behaviour is driven primarily by anxiety, making the person feel that demands threaten their sense of autonomy.

• Surface sociability: People with PDA may appear more socially capable than those with other forms of autism, but their social interactions can be superficial and used as a way to control or manipulate situations.

• Mood swings and impulsivity: Sudden changes in mood, along with a tendency to be unpredictable and highly sensitive to perceived control from others.

• Creative strategies to avoid demands: Individuals may use a variety of methods, including distraction, negotiation, or even resorting to tantrums and aggression to avoid complying with requests.

Management:

• Flexibility: Approaches that avoid direct confrontation or demands and use collaborative techniques can be helpful.

• Supportive environments: Reducing anxiety and creating environments where the person feels they have more control often improves behaviour.

• Therapeutic interventions: Techniques to manage anxiety and provide coping strategies.

​

ODD (Oppositional Defiant Disorder)

ODD is a behavioural disorder characterized by a persistent pattern of uncooperative, defiant, and hostile behaviour toward authority figures. Children and adolescents with ODD display frequent temper tantrums, argue with adults, and defy requests or rules. Unlike PDA, ODD is not considered part of the autism spectrum.

Key Characteristics of ODD:

• Angry and irritable mood: Frequent temper outbursts, irritability, and easily losing temper.

• Argumentative and defiant behaviour: Often argues with authority figures, actively defies rules or refuses to comply with requests.

• Vindictiveness: May act spitefully or seek revenge against others, often more than once.

• Blaming others: Tendency to blame others for their own mistakes or behaviour, leading to further conflicts with parents, teachers, or peers.

Management:

• Behavioural therapy: Techniques like positive reinforcement and parent training are commonly used.

• Consistent discipline: Structured environments with clear rules and consequences help manage behaviour.

• Counselling and support: Family counselling or individual therapy can address underlying emotional issues.

​

Differences Between PDA and ODD:

• PDA is associated with autism, while ODD is not. PDA behaviours are driven by anxiety and a need to control, whereas ODD is more related to oppositional behaviours toward authority figures.

• Avoidance in PDA stems from anxiety, whereas ODD involves intentional defiance and anger-driven opposition.

Both conditions benefit from specialised support, but the approaches differ depending on the root cause and the individual's needs.
