This poster summarises research on the behavioural features of extreme/pathological demand avoidance (PDA) using a semi-structured interview with parents of children diagnosed with autism who also displayed PDA traits. The study identified key areas of difficulty, including struggles with following demands, controlling behaviours, extreme reactions, engagement in fantasy/role play, avoidance strategies, poor social awareness, and intense emotional instability.

The findings highlight the significant challenges that PDA behaviours create for families and schools. The paper stresses that these behaviours should be properly assessed to develop effective management strategies tailored to each child’s needs. Recognising and addressing these behavioural difficulties early can help improve support for children with PDA, their families, and educators. This research contributes to a better understanding of PDA within the autism spectrum and reinforces the need for individualised approaches in assessment and intervention.
